Bryan Johnson reduced his oral biological age by 20 years through daily water picking, tea-tree oil, and eliminating foods that damage teeth. His dentist couldn't make his gums bleed even with aggressive attempts. He credits the shift to stopping 20 years of teeth grinding and cutting out poor-quality foods.
There's been a lot of connection to oral care with the rest of the body. I'll do a water pick for gum cleanliness, then tea tree oil. My dentist is, I think, in her late 20s and my plaque index was lower than hers. She tried very hard to get my gums to bleed and she couldn't do it. I've reversed my oral health age by over 20 years. A lot of that had to do. I think one, with diet, eating bad foods is just bad for oral health. Number two is I had bruxism for over 20 years.
