Dermatologist Shereene Idriss warns that mouth taping at night risks low oxygen for people with sleep apnea, allergies, asthma, or a deviated septum, causing morning brain fog. She suggests trying it briefly during the day first, and recommends NuFace or Zip devices, better posture, or seeing a dermatologist for jawline concerns instead.

Have sleep apnea, if you have allergies, if you are somebody who has asthma, if you have a deviated nasal septum, the risk of taping your mouth shut at night is going to decrease the oxygen flow to your brain and you might feel a little bit delusional in the morning because you didn't have enough oxygen overnight, but it's not going to help you look better. And quite frankly, this is where vanity will kill you in the long run. So if you're only interested in mouth taping for a better jawline, there are other options and I would suggest you start with trying it out first during the day to make sure that you can tolerate it and that you can breathe adequately. Maybe do only 10 minutes if you are really so inclined, but there are really other options at home. Devices like the NuFace or the Zip device which really help with electrical microcurrents can help to tighten your jawline. Additionally, trying not to look at your phone while looking down is going to help to decrease the incidence of technic. And last, you can always see your board certified dermatologist or local provider.
