Does anyone use a mouthguard?

Bruxism is a disease that makes people bite and grind their teeth when they sleep. It's very damaging to the teeth.

To protect the teeth, some people use mouthguards made of plastic. One potential problem is that plastic is absorbed in the mouth, directly to the bloodstream. Some people also use mouthguards when playing violent sports.

Would the amount absorbed by sucking plastic every night for 8 hours be enough to create problems?

You can use magnesium supplementation instead.

Just before bed. It helps with the grinding plus other muscles that might get contracted during night. It's good for the body. You'll sleep better no matter with or without mouthguard. AND you won't absorb any plastic. Plus you won't scare your partner at bed. Plus the effect is cumulative as you replenish your magnesium stores.

Ray Peat has some comments about magnesium:

Before knowing Ray's opinion on magnesium, I also found that carbonate and chloride were very good forms, whereas citrate and oxide are BAD. (personal opinion)

Two teaspoons of Mg Carb. in water before bed with a bit of something acid to avoid gas.

And remember to never use mag carb with food, as the carbonate counteracts tomach acid.

Good luck!

Btw, at a psychological level, I think bruxism has to do with repressed anger.

Would you mind elaborating on why Magnesium Citrate is bad? Thanks!

I can't elaborate on it more than personal experience. I found that it gave me nausea and I became very intrigued. Looked for some info on the internet and found a couple of dudes having the same problem.

Of course many people don't have issues but since Ray Peat advises caution with it (don't forget to read the link I posted) I discard it's use.

Thanks very much!

The beneficial effects of the guard probably outweigh the negatives. Teeth grinding is very stressful and can do permanent damage to gums and teeth.

Better to use the guard while trying to fix the root problem of the grinding. I've seen a pattern that the peat style diet causes grinding in people - I believe this diet is stressful and that this stress creates a situation where someone starts grinding at night.

Get your grinding under control before your teeth move too much.

Try eating more non peat foods to see if the grinding will stop. It did for me when I ate more fibers (starches, vegetables, more fruit types, and added in all meats aside from pork).

"The beneficial effects of the guard probably outweigh the negatives".

Of course. I'm asking what the effects of the plastic would be. Could they have a harmful hormonal effect that provokes grinding, and thus create a vicious cycle (mouth guard => more plastic => more grinding => more need for mouth guard)?

I had the grinding years before Peating, and many other problems were fixed by eating Peat foods, so I think they're helpful. I wonder though if the plastic I'm consuming puts a barrier on my improvement.

There's nothing stressful about a diet following Peat's principles. You might implement it in a stressful manner, but that's your mistake, not Peat's.

Bruxism is from psychological stress. I speak from personal experience. If you're doing something stressful that will net you a $1mm payday within a few years, by all means wear a mouth guard and suck it up. Otherwise, take stock of your life and take necessary measures.

Last night I put a piece of carrot in my mouth instead of the mouthguard. It seemed to work, at least one day. Hopefully it doesn't create harmful maladaptations.

It can be dangerous to keep food in your mouth while you are sleeping.

It's been 7 days. I haven't die. I make a whole in the carrot with my lower teeth so they sort of stay in place. I woke up with them in the same place every day except once when I woke up in the middle of the night with the carrot in my hand.

Having a food in my mouth though might mess up my glucose regulation throughout the night, but I think that's better than sucking plastic all night.

ok, I do not want to scary you but recenly a student died because he had in his mouth gum while sleeping.
