A number of people recently have talked about dental problems possibly related to their Parkinson's Disease. I have not had dental problems but I did have dry mouth problems while sleeping. I would sleep with my mouth open and would wake up four or five times a night with a completely dry mouth. Then I would drink some water and try to go back to sleep once again -- not always immediately successful. I looked for some way to avoid the problem and after quite a while came up with a solution. There is a mouthpiece on the market which forces one to breath through the nose rather than through the mouth. The mouthpiece is made to eliminate snoring. I don't know if it is successful but it does allow me to eliminate dry mouth on most nights. If dry mouth contributes to dental problems then the mouthpiece may reduce that problem too. The name of the company is Snoring Relief Lab Inc., 11470 Sunrise Gold Circle #7, Rancho Cordova, CA 95472. Telephone number is 800-753-3716. The name of the product is Snor-Ban. I hope this helps with the dental problems and sleepless nights for others too.
