I was amazed by what dr karen can do. (she is a dentist with an engineering background). since i grind my teeth, my old dentist made me a bite guard...but it made my jaws hurt and my joints started popping. i knew i was getting worse instead of better. when i went to dr karen, she was able to work with my jaw's natural bite and transform the bite guard into a perfect bite-pain is gone, popping is almost gone. now i can rest without hurting myself!
