And most likely the jaw would get broken if hit hard enought to cause a concussion..

and broken or chipped teeth!

I am sorry, I did. not answer back then.

You were right, it was nothing. Just an anxiety response. I think I had at least one real concussion some years ago, but I have been struggling with anxiety and stress over the years.

More recently, as it’s getting more cold, my jaw muscle sometimes involuntary contracts and again my front teeth collide. Like my teeth are starting to chatter when my mouth is open. I try to avoid it, but it has caught me by surprise a couple of times.

Most of the times the contact is light, but at times the spasm feels more violent. I am afraid it might have a cumulative effect on the brain apart from the teeth, if I can’t avoid it consistently. I am afraid it might be up to subconcussive. Although it happens rarely at the moment.

I have felt “feverish in the head” for some days, but I think this is caused by bad sleep and stress. I try to take vitamin B and omega 3 supplements and reduce stress in any case.

Also I tried to calculate the accelerations, but it’s senseless without knowing how far tooth ligaments do contract under forces. I don’t even get a good estimation of the order of magnitude. And also I would know what it would change, if I had a result.

You might try physical therapy, acupuncture or such for the spasming jaw muscles..

andyMunich,

NO. It is not even close to a sub-concussive impact. They require 20 Gs or more.

You need help with your anxiety. Your jaw action can be caused by anxiety, stress, medications, or a movement disorder.

L-Theanine can help you relax better. 5-HTP is also helpful.

Amazon has a 5-HTP supplement with L-Theanine, GABA, and L-Tryptophan by Amazon.com

Thank you very much for your replies.

I will try the supplement you suggested. I will also consider therapy.

I am also actively trying to reduce stress in my life. Stress is almost never worth the thing it’s about.
