Dr. Dominik Nischwitz: The Hidden Dangers in Your Oral Hygiene Routine | TUH #085

Go in every aisle in the supermarket. When it comes to conventional oral care, you have the usual suspects of fluoride containing toothpaste. And then you have Listerine. Look at the history of it. It is designed to clean a floor or maybe your toilet.

What are some of the signs and symptoms that your oral cavity needs attention?

Ask yourself these three questions. Metals in my mouth, root canals, wisdom teeth, pool. If any answer is a yes, you might have something called oral interference. Stuff that is imbalanced in your microbiome, your immune system, and your nervous system on a daily basis. You do everything to optimize your health, but you still don't feel superhuman. Then it's at least time to find a good biological dentist to sort out that oral interference.

Aside from getting their root canals cavitation fixed. Talk about daily oral hygiene.

The conventional dental hygiene is actually outdated. Therefore the two space that I would recommend is always.

Ultimately wins. Hey guys, welcome back to the ultimate human podcast. I'm your host, human biologist Gary Brecke, where we go down the road of everything anti aging, biohacking, longevity, and everything in between. And today's guest is in a very, very, very special guest. You're going to really enjoy this podcast. He is the world's leading biological dentist and he trains other dentists, including the dentist that did the work on my mouth in the practice of biological dentistry. Not familiar with biological dentistry. This is a must watch episode because you are about to learn the importance of what goes on in your mouth and how it is connected to all of the organs in the rest of our body. Our mental health, our gut health, and our overall wellbeing performance and our longevity. So welcome to the podcast, Dr. Nischwitz. Or we call you Dr. Dom, right? Dr. Dom Nishwitz. Can I go with Dr. Dom?

Perfect.

Okay.

Thank you for having me, Gary.

You know, I'm really excited to have you on because, you know, my audience knows that, um, I've really been on a mission to give biological dentistry a voice ever since. I had a very personal journey and my wife and my daughter, both of my daughters actually had a very personal journey with, with a biologic dentist, Dr. Jagar Gandhi, that you trained. Yes, as a matter of fact. And he speaks very, very highly of you. So to. To have the sensei on, you know, I actually had him inspect my, my, my dental work before, before the podcast, I was opening my mouth and showing him the implant. You know, and just for those of you that are not familiar with my story, just very quickly, I. I had two root canals and One of my teeth on the side. One of the sides I had a root canal on cracked. And so Dr. Gandhi is, you know, Dennis, he's a friend of mine. He obviously did not do the root canals. And I called him, and I said, hey, I cracked this tooth. I really got to come up and see you. And at the time, I wasn't coming to see him to have the tooth extracted and to have all of these procedures done, but, you know, he said, take a picture of it and send it to me. And I did. I said, so I took a picture of the tooth, you know, in my mouth, and I sent it up to him. And it was the 19th tooth meridian. And so he asked me a series of questions that really freaked me out. He said, let me ask you something. Do you ever get left anterior shoulder pain? And I go, that's really funny that you asked me that. I go, yeah, I thought it was a bicep tendon catch right in the front of my shoulder. And it wasn't enough to stop me from training, but I was very conscious of it. And then he said, do you ever get left lower lobe lung pain? And I go, dude, you are freaking me out right now. I go, whenever I do hits cardio on my treadmill, I get a catch right here. I get this left lower lobe lung pain, and I have this numbness right, right here. And I thought it was like a runner's cramp. And then he says, does your left toe ever go numb or does your left toe bother you? And I go, now I'm completely freaked out because my wife was always kind of making fun of me because sometimes I would take my shoe off and I would actually itch my left toe or I would tap it on the ground because it felt like it was going numb. I never put these together. So he goes, that's your 19th tooth meridian. When we. When we take that out and clean it up, all that's going to go away. Yeah. So the biohacker in me kicks in, and I go, first of all, why wouldn't I know about this? Second of all, there's no way that all of that is going to go away from cleaning this tooth out. And long story short, I went up to see him. He did the PRF red light green light, ran ozone into my jaw, cleaned, cleaned it all out, and then put the ceramic implant in, which. Which you taught him how to do. And what was the Most astounding was 48 hours after this happened, none of those symptoms have returned. They permanently went away, and they haven't straight away. Straight away, my wife, five days after having her root canals done by Dr. Gandhi, her back pain went from a constant 6 to 8 to a constant 0 to 2. Like. And very quickly, my, my daughter had headaches that she no longer has. So. And I could just go on and on and on. But what really astounded me was when we pulled the tooth out and I saw this little sac, the cavitation. And I asked Dr. Gandhi what it was, and he told me that it was full of bacteria and pus and parasites. And I said, there's no way I would have had pain. I would have had swelling, I would have had inflammation, I would have had symptoms. And when we burst it and we put it on a dark field microscope, I could see the macrophages going after the, you know, the bacteria. And I was sold. And I said, I am on a mission to tell people about this and to bring the practice of what you do to light. So I'm, I am really, really excited to, to have you on the podcast. So for those of people that don't know what biologic dentistry is. Yeah, right. I mean, everybody knows what a dentist is. What is the difference? What is the mission of a biologic dentist? How are they different from the regular practice of dentistry?

Yeah, I always say it's just the next level is the dental evolution. Because obviously dentistry is a high tech craftsmanship. And the way I define the Biodentistry 3.0 concept is it's the overlap of that high tech dentistry with functional medicine and health optimization or biohacking. And the goal is obviously not to, not to just fix bites and smiles, but to repair the overall body and help patients to really heal, like you just said. And this is like, every dentist loves that tiny work, which is they need to do this right. But the fulfilling part is if you tell me, oh, all the symptoms are gone, because this gives me goosebumps. Up until this day, even though I do this already for 15 years, it's like, wow.

Yeah.

And this is how impactful it is. If you understand that the mouth is the gateway to overall health. It's actually the entrance to your gut system, entrance to the body. And the teeth are not just teeny, tiny heart biting things. They're literally tiny organs directly connected to the brain. Nerve number five, trigeminis.

Wow.

And therefore everything you do on these teeth or you repair teeth will affect the whole body.

Yes. You know, it's funny because when I. Not, well, not funny, sad, I guess when, when Dr. Gandhi and I did Our podcast and I aired our podc. Um, it actually got censored. Still is on Instagram. If you go to my Instagram, it says false information. Oh, man. I don't know who the fact checker was, but they fact checked it and, and literally says that teeth are not connected to other areas of the body. So in other words, what happens in your teeth where your gums or your jaw is not going to affect the rest of the body? And how do you, how do you address that?

Yeah, this is the main issue in conventional dentistry is that we're basically not connecting the, the mouse to the body. It's kind of like it's an outside realm where you can just. But if you just look at an anatomy, anatomy chart and you see the, the trigeminal nerve, you can see that this goes up until the, the tooth, every single tooth has a connection to that nerve. So telling that it's not connected makes no sense. Just like telling. Like we said before.

Yeah. Cranial nerve. Right.

You have 12 cranial nerves.

Yeah.

And the trigeminal one basically has three branches. One here, one here, and like upper jaw. And the other one is the complete logo. So as you know, when you go to the dentist and they give you a nerve block, everything is numb. That's because it starts here.

Right.

And. But it's completely not logical. Not logical that they say is not connected, but obviously they're referring to that meridian system that we're always showing, because meridians are still in the woo woo realm versus, if you go to traditional Chinese medicine, it's just how they treat. It's basically just an autonomic nervous system. If you understand how the nervous system works, the sympathetic and the stress axis, then you understand whatever chronic inflammation or toxicity you put into your body will affect the whole system. It's kind of like if you take a hormone, you know that it will affect all your cells in the body. So why do you think it doesn't do it in the mouth? It is because in dental school you not, I wouldn't say brainwashed, but it's really about repairing teeth with whatever material. So in the last century and still up to this date, we use a lot of different materials, especially metals. Yes, because they work for biting, but they never connected that they might interact with the whole nervous system, the whole immune system, the detoxification system, this. And for example, in university you have to study sciences. In medical school, in dental school, it's the same as medical school. So you study biochemistry, you study chemistry, physics, microbiology, everything but you basically learn in university that you should not put different metals right next to each other in physics in the morning because you know that there's a battery effect and that these ion will travel. But then in the afternoon, you go in dental school and repair patient and put a gold crown right next to an amalgam filling. So it's kind of schizophrenic. You learn all these sciences, but it's like you're just the dentist.

Yeah.

And this is the problem. And this is why dentists always have this connotation of, I hate to see the dentist. No one wants to go there.

Right.

It's a repair business. Drill, fill and bill. And this is what I'm going to do. That's what I want to change. Because patients that come see us, they're in for the complete treatment and they tell you, I lost my problems with my gut. I have no more frozen shoulder, my mental health issues are gone. I have no more eczema. And by the way, he also put in beautiful teeth. So, yes, that is the focus. Like, it's a complete holistic approach to optimizing one's health.

I think it's absolutely got to be a part of somebody's optimal health journey. I mean, if you, if you're listening to this and you've had root canals or you have dental work that you haven't been addressing, now is absolutely the time. Time. And I'd be happy to provide you with a list of, of dentists that, that, that he's trained. Because my personal experience is one that really has driven me to be passionate about this subject. And then when my wife and my, my oldest daughter and youngest daughter all had the very similar experiences, I said, this, this can't not be the case.

And this is, this is. This is still the fulfilling thing. And if you do it like myself, I do that for half my life. You, I have that moral obligation to tell. Because it is so insane. Yeah. That if you realize, oh, wow, even myself, I had the wisdom teeth pulled like almost all of the people out there.

Right.

And I didn't connect it to my various health issues. But then we found cavitations at one point, and in surgery for myself, I realized, oh, wow, my chronic back pain goes away. And had to laugh and told my surgeon back then, is this even possible? Then I had skin issues a lot. And then my diet was already on lock, like, perfectly right. And all the things you do, but it wasn't good. And two weeks after surgery, I had beautiful skin again. After five years And I had like a little bit of a nervousness in the morning. Really thought, I thought early 30s, I thought I'm going to get Parkinson's or whatever.

Right.

Also gone straight after surgery, never came back. I understand why, why that is. Because if you have chronic inflammation and there's toxins in there, there's parasites, virus, it's, etc, they affect the immune system, make you more autoimmune prone and shift your TH1 to TH2 system. But also just it. Chronic inflammation produces stress. It's a stress.

And when you have that chronic inflammation related to the jaw, you're talking about these, you refer to them as cavitations. These are, these are pools of inflammation, bacteria, parasites.

That's one chronic inflammation to jawbone. The other one is the root canals. They're usually chronically infected. If you really being precise when it comes to diagnostics and use a three dimensional cone beam, you literally in at least 80% of all cases you see some sort of chronic ongoing inflammation on, on the tip of the root.

Yes.

But the problem is a usual dentist will only ask you do you have pain?

Yes.

No. Okay, then we just monitor it. But which, which chronic health issue is pain? Is it painful to have depression? No. Is it painful to have eczema? Not really. So it's, it's the wrong, the wrong tool because a chronic inflammation is basically the body got used to it and reduces the, the, the volume, the receptors basically. So you don't feel it anymore.

Right.

So therefore you have to.

Well in the case of canal you've actually killed the nerve. Right? So, so you killed it. So now you could have pain, you just don't feel it. Right.

You killed it. And also because it's an ongoing chronic inflammation, your body just reduces the pain because it's kind of like a, let's say a laziness of the body because it has no solution for it. So it just reduces it makes it a little bit numb. If the stuff is numb, it's really bad because you, then you don't connect it anymore. So you maybe like you have that root canal and you have a frozen shoulder, but you would never connect it because first of all normal medical school doesn't teach this.

Right.

And most dentists don't understand. So this is where I come in and teach. Hey, it might be your chronic knee pain comes from that root canal over there.

Yeah.

If you understand fascial trains and all.

How how an infection in the mouth of the jaw that you that doesn't have pain. Because I didn't have pain.

Yes.

And I didn't have symptoms. Well, I mean, I guess these could be my symptoms. But by symptoms, I mean I didn't have something that would have driven me to urgent care center. Yeah, right. I wasn't sniffly, I wasn't achy. You know, I didn't have any kind of fever or, you know, rashes or any of the typical symptoms. And. But the symptoms that I didn't know were connected. Absolutely went away after the treatment. But talk to me a little bit about what these cavitations, how are they related to.

Yes.

The other parts of the body. What's the mechanism by which they're connected?

So basically a cavitation is the layman's term for something called FDOJ in medical terms. Fatty, degenerative, osteonecrotic jawbone. That's basically what it is. Mushy, fatty bone. This is usually from extraction of teeth. Which teeth are mostly extracted in the Western world, at least because of spacing issues. It's your wisdom teeth. Therefore I always ask three questions on every keynote is like any metals in your mouth, any root canals, any wisdom teeth, please stand up. And at the end, 95% of the audience will stand up.

Wow.

Especially on the health optimization summit and biohackers, they should know it, but it's not connected as a foundational principle. Huberman just lately put it into his at least.

Right.

The problem is it's oral health for now. Like the WHO talks about it. It's mainly like the WHO says 70% of all chronic disease start in mouse, but they only look for the gum disease, the tooth decay and the periodontitis. But then the repair is not in the thing. And, and these cavitations Resulting from previous dental extractions could be every, every single tooth, to be honest, is just the, the problem is that the dentist basically just informs you about the local procedures. You will maybe have a swelling, you need to apply cold, take the antibiotics, take the painkillers. But there's no systemic preparation of patients leading up to your surgery. Especially when you're like in your childhood or teenager years and growing up with these wisdom teeth. So what happens is your body is in, I always say it's in hibernation mode, not in an anabolic state, more like catabolic or uses a lot of nutrients to just grow but not heal. Therefore people oftentimes develop dry sockets, which means it just doesn't heal. Then they have to go back to the dentist and they will put in like a local antibiotic and leave it open for healing. So therefore it basically is a secondary healing and doesn't really heal. And over time it's kind of like a construction site that never stops. And because it gets ischemic so there's no more, no more oxygen in there. It's the perfect cave for bacteria, anaerobic bacteria that are anyways living in your mouth. It's a huge microbiome, they like to live in there. And in the US especially mold is a big thing. Mold spores tend to live in these cavitations. They also found mercury, heavy metals, glyphosates, parasites, parasites, fungi, everything in there. And it's a chronic thing. That means again, body dials down the volume, you don't hear it anymore, there's no local pain usually.

Right.

But systemically, like you had it, but you would never connect it, there's a problem. And if you see just the wisdom tooth area on that tooth meridian chart is directly connected to your central nervous system, to your heart meridian and small intestine. Small intestine again, sibo skin eczema, thyroid.

Issues like recurrent sibo, like and for.

Example, yeah, if you don't, if you seem to, like this is what I always say, if you seem to do everything perfectly, like you said, lifestyle is on, on point. You do your training, you track your sleep, you do everything to optimize your health, but you still don't feel superhuman, right? Then it's at least time to find a good biological dentist to sort out that oral interference stuff that holds you back.

And start with this cone beam, which is the machine that I put my head in and it took like a 360 degree cone beam view. And when he showed it to me, the cavitation and told that it was full of bacteria and pus and, and, and parasites and what have you. I was actually a little skeptical until we actually burst it and put it on a slide and I looked at it under darkfield in the back of Dr. Gandhi's office and I could literally see my macrophages going after bacteria and other things in that cavitation. So I was like, there's absolutely no, you know, chance that that's not, not true.

Yes, but the problem is this is something you don't learn in dental school. Therefore, if you have a cone bean done by usual conventional dentist, they won't diagnose this area because they, they don't even know about it. So if you have a combine, you have to have a dentist that is skilled to find these cavitations or at least know about it. It's a bit of a thing because they're not connected. And you know, these cavitations, besides being, let's say, a dumping area for toxins and all these things, they also contain a specific chemo kind. It's called rantes R A N T E S or CCL5 in medical world. And if you type in or Google Scholar, Rantis plus, let's say multiple sclerosis, we'll probably find 3,000 papers straight away. So yes, medical world is looking for the Rantis, but they don't know about cavitations and dentists don't know about cavitations and maybe have tested runties but don't know how it's connected. Because Rentis is basically not a bad thing. But if it's chronically activated, it's like an ongoing construction site. It's never, never stopping. And then at one point it flips.

And what is rantis?

That's a chemokine.

It's a chemokine.

It's actually chemokine lignin 5, CCL 5. So both of them are corrective to search for them and they are highly represented in these cavitations. But cavitations, again, they're not accepted in university or not trained yet. Therefore 99% of all dentists will tell you that's quackery or that's woo woo, that's not existing. Even though they see it. Maybe it's like, right, it's normal that there's fatty tissue in your jawbone. No, it's not normal that there's fatty tissue. It's a sponge's bone. Why should there be a chronic inflammation? Right, Yellow bone is not good.

Yeah, and, and, and I think, you know, Dentistry has got to be the only practice of medicine, in my understanding that thinks that it's okay to leave dead tissue in the body. You know, I mean, it's. It's dead tissue.

I always say it's never been a good idea to leave a dead body part in the body. No medical profession would do.

Yeah. I mean, if you have an appendicitis, you gotta take it out. I mean, if you have necrosis in your bowel, they. They resect it, right?

Yeah. Or if you have like a diabetic foot, they take it off. If you have a diabetic finger, like gangrenous stuff. That's gangrenous stuff in your mouth. It's kind of like the splinter in your hand that never goes away. Or an ingrown hair. But it's not like an ingrown hair, let's say a splinter on your arm, you will know, oh, there's an inflammation, it needs to come out. Right. Because you see it, but here you don't see it. But actually, it's even the worse because this is central system, this is your brain. It's an extension of your brain. So for your body, this is way more complex than just having to lose the arm. It's like really inside of the nervous system, chronic inflammation and. Yeah, chronic inflammation is killer, number one.

Yeah. It's the root of all evil. And I was reading recently about the similarity, the identical similarity between bacteria in the. In the jaw and bacteria and cardiovascular disease and the specific strain of bacteria that they are finding in high amounts in cardiovascular disease. Advanced stage cardiovascular disease.

Yeah. There is actually a theory going on, and I had it with Stephen Gundry yesterday. He is a heart surgeon. He, in his opinion is that the plaque in your coronary arteries and stuff is kind of like a. It's just a biofilm. And the main station for all the oral pathogens is usually the heart is next. We know that in dentistry.

So say that again.

So to. It's like biofilm is basically how bacteria and colonize. Like biofilm in the mouth, for example, is if you drink a Coke, within a minute, you have like a fur on your teeth.

Right, right.

You know, where is this? And this is just bacteria going in there. And this happens everywhere in the body. Like, biofilms are on your fascia, in your gut, but also in the heart. So if you get that plaque in your heart, this is connected to pathogens. And these pathogens usually stem from the oral cavity, because the second station, when it is swallowing of the bacteria, which you do about 140 billion a day.

Right.

And they go straight into your heart. And we notice in dentistry because if someone had an endocarditis before, we have to give them antibiotics before even doing an oral hygiene appointment because we know that we stir up bacteria that go in there. But now we have a root canal which leaves you with a dysbiotic area, meaning more bad bugs in there, usually activating your innate immune system, producing cytokines like TNF, alpha illness 4 etc and these pathogens then also obviously can travel. And the infection goes from the tooth, through the lymph, through the blood with it. It is in your, in your body, within a minute in the blood. And there is studies showing like one of the bad bugs in the mouse is always streptococcus mutants as well as porphyronus gingival is. And there's a neuro study showing that even neural neuro inflammation caused by activation of glial cells comes from oral pathogens just as porphyronis gingivalis, which is, it was able to jump into the system. Why? Because you don't have leaky gut, but you have leaky gum already, which is bleeding gum.

Wow.

So bacteria just jump in. And this is how they find it in the brain. They find it in the joints, they find it in the hip joints and knee joints.

And they're coming into the oral cavity.

Extremely connected to rheumatoid arthritis.

Could they possibly originate from one of these cavitations and then leak from the cavitation into the bloodstream?

Yeah, exactly. They could leak from the root canal, it could leak from the cavitation because it's directly connected. So the nerve, even the trous, transports oral bacteria, toxins, chemokines into the brain stem. It's called retrograde axonal transport. And this is proven since the 1920s when they put in toxic croton oil into teeth of dead, of, of, of dogs. And they could find all the toxins within 24 hours in the hypothalamus, the pituitary, all the brain ganglia.

Wow.

Understand this. If you understand how complex the systems and how simple it actually is, if you understand the complete human body, then you then it's just like, ah, makes sense, right?

Right.

Something here can leech out. And there's also studies showing for example, that rantis is connected to even breast cancer like this chronic activation. And you can find all of it, but it's not, it's not really, it's not connected yet.

We've long since been told that, you know, the metals in the mouth are not a good thing, Right. Because they're conductive and they're interrupting not only meridians but neuronal pathways. But talk a little bit about how that occurs and because there are a lot of people listening right now that have mercury fillings or have silver fillings or have fillings that are other types of metals. Golds. Yes. And then I also want to talk about braces because, you know, two of my family members had braces growing up. And you know, when I think back, like, well, that's a lot of metal in the mouth for a long period of time.

Yes.

So what are your thoughts on that? And talk a little bit about dangers of metals in the mouth.

So basically, metals come with three challenges. So let's say they're just you. So in dentistry, you use all sorts of metals to repair teeth. The one filling you're just referring to was the silver black filling, which is called an amalgam filling. And this contains 50% of mercury. And we know that mercury is the most toxic non radioactive element known to men. And as soon as we take it out from the mouth of a patient, we have to remove it as highly toxic waste. But in the mouse, for some reason, it's super healthy and completely bound. It makes no sense. Hold on.

So as soon as you take it out, you have to treat it as highly toxic?

Yes, we have to. It's really. There's someone coming in, like a special delivery system or picking up system to take it away. Yeah, we also, we know all this, but obviously this material is super for filling and super simple and it lasts forever and insurance has subsidized it. So finally, I think finally in 2025 they banned it in Europe finally, versus like in Russia it's banned for 30 years. In Scandinavian countries it's banned for almost 20 years because they have a general mercury free environment strategy. So you cannot put it in the mouth. And for me back then it was just an ugly material. I could never place a black filling if I can do a white one.

How long ago in America could you still put mercury in the mouth or can you still do it today?

In America you can still do it today. Ever since 2018 there was a convention, the Myanmar Convention. You're not allowed to call it silver fillings anymore. So marketing was silver fillings. There's a little bit of silver in it, but it's 50. It's mercury filling. So they now have to tell you it's mercury filling. Yeah, at least. And I think it's only a matter of time. Usually the Germany hangs on the to the U.S. so us comes first, but in this case Europe comes first or Germany and I think then at one point the US should also stop using these. Yeah, really toxic fillings. So it's in metals the challenges are always toxicity, which would be the mercury is very toxic.
