I have broken incisors from night grinding and had absolutely no idea that it was happening. A $1 night guard has solved my problem… except I now need $10K of veneers work to correct grinding problem.

I really enjoyed reading this article. It was to the point and helpful. In 1990, at 16, I was in a horrible car accident where my jaw was fractured. 2 plates were put on, then taken off as I was allergic to them. Since then, I have had pain everyday. The muscles on the right side of my face throb throughout the day. The heat makes the pain last even longer which is why I left Florida to move back home to Ma. My face loves the cold weather. Thinking about trying botox, not sure. ? The only thing that helps my pain is ibuprofen, hydrocortizone and cold weather.

This is one of those things I know I need to do but I don’t want to. I grind my teeth. I got fitted for a night guard a decade ago, found it unbearable and haven’t tried it since. I do have a dentist appointment coming up in March so I will revisit it again. (Grumbles) Just kidding! Thank you for the informative article!

Dana, I tell you from experience. If you need one get one (and use it no matter what). I have slept with a night guard for probably a decade now. I tried several OTC ones but they didn’t w
ork. I am on my second dentist made guard because I bit the other one in two (over time). I see that the newer model has a metal piece in the spot where I split mine. I looked into getting one maybe 15 years ago and was annoyed that my insurer would pay $0 toward it. I wound up splitting a pre-molar that cost a lot more!

You’re crazy allowing this to go on. At 36 my doctor told me I had the arthritis of a 90 y/o in the TMJ. My jaw has locked more than once. This is serious and getting used to the guard is easy. Don’t wait until it’s too late and you live to regret waiting.
