Clenched jaw

When you are as "lucky" as I am, and have two major chronic diseases, it is difficult sometimes working out what symptoms and pains are associated to which disease. Many occasions in the past I have experienced pain in my lower jaw bone which is considered a "long bone" and therefore this unexplained pain that comes and goes is put down to Gaucher disease. Unwittingly, I have recently been clenching my jaw tightly shut, and after some days I realise my jaw is painful and my teeth feel like they are going to erupt. I have since heard from fellow sufferers that I am not alone with this additional symptom. One person had a night guard made to wear during the night to protect the teeth and cushion somewhat the jaw clenching shut and grinding teeth. The pain can radiate up towards the ears and I presume this puts pressure on the teeth too. Having had  a crown fitted recently, I have suddenly found that it feels like it's slipped out of place. I guess I will making yet another visit to our friendly dentist. Just when you think you know all the symptoms that Parkinson's has to offer, something new appears on the scene. I have always meticulously cleaned my teeth twice a day, floss, use mouth wash, and go to the dentist as soon as something appears to be wrong, and yet I am beset with dental problems. I know other people who don't seem to take much care of their teeth and yet require little or no treatment at all. I suppose good teeth is down to one's DNA. How common is this problem?
