I have been told that I grind my teeth in my sleep since I was in middle school. In the past 4 years I have had problems popping my jaw in and out while sleeping and throughout the day. I have done research, and I think that I have TMJ. I have set up a dentist appointment to get a custom night guard.
I have noticed that my teeth have become very sensitive to sweets like chocolate. I also have been getting small headaches that make it hard for me to do simple things such as read and talk to people without having to squint.
I highly recommend Rolfing or Craniosacral Therapy to help treat your TMJ syndrome. In regards to your tooth sensitivity, stay on course and see your dentist. I am an Advanced Certified Rolfer and have helped people with TMJ syndrome. Good luck.
