I have just very recently started biting (severely) the inside of my lower lip..... Sue: Some weeks ago I asked members about these and similar "biting" symptoms. My first dentist was not very helpful and I cracked two caps.So the situation is not only painful, it is extremely expensive! My new dentist made me a light retainer to wear at night, but I find myself grinding away on that as well.Another option would go to a heavier material--not too comfy if wearable at all. Another dds told me that jaw tightness may contribute; tension gets to a point where there is sudden slippage of a disc, and the teeth snap shut, involuntarily and forcefully. This usually occurs at night or when falling asleep. My neurologist had no suggestions, and did not think it related to PD. Stress and pain may be other factors. I hope we can find a solution...soon!
