I have the mouth piece i wear at night. I clench my teeth very tight but have dine this for for mote years than i have .been on my PD med since 2012

@albatross I have that problem.I've also bitten my tongue and cheek. There is a fairly expensive solution. It involves having. a plastic insert made to protect you from grinding. My dentist suggests it.btw I sometimes suddenly snap my teeth together.

I do that, i even seem to be clenching during the day.

I don't have Parkinson's personally my 81 year old mom Ann has it an she realized to her jaw was hurting an realized she was clentching it shut

I have done it since diagnosed with PD, I have 3 cracked teeth from it. It’s a real pain and annoying to the max. God Richly Bless you.
