When I wore braces a few years ago, I started to have a cracking jaw. When my came off, the cracking of my did not go away. The other day, I decided to seek treatment for this. The dentist told me to use a dental guard. Is this what I really needed? I have read somewhere that a dental guard is for those who have teeth grinding habit. I do not grind my teeth so I am not sure if this is what I need. Any ideas? For those who have problem with cracking jaw, how did you treat it? Please give me some tips! I would be grateful for any information.
