Chattering teeth will also grind while u sleep. It can affect the nerves in your mouth making your teeth sensitive to hot and cold A dentist can make a special mouth piece that u wear on your bottom teeth while u sleep.
@A MyParkinsonsTeam Member (awesome name!) my dentist says people with PD can have several mouth/tooth problems. Grinding of the teeth is definitely one of them, but also increased bone loss and difficulty getting them clean because of tremor. Mine gave me a prescription toothpaste to help with the tooth sensitivity and getting them clean. An electric toothbrush also helps a lot in getting them clean. It is a royal pain though, there's no doubt, but like you pointed out, a mouth guard can open your mouth easier.
Thanks for the idea.
My jaw and tongue dance so much little kids ask me why my tongue and jaw "jiggle" or "wiggle". I tell them that's just the way God made me. (Not all parents appreciate that answer, but oh well.) My medicine has helped a lot; it doesn't get rid of it, but it's not quite so obvious as it was for many years.
I was told by the dentist that people with PD tend to have problems with cavities and other mouth problems because of dry mouth from medications and also grinding their teeth at night, and even during the day. For the dryness I sip on a lot of water. It helps; in the 40 years I've had PD only 2 cavities have shown up. But I work hard to keep the teeth healthy. Good DNA helps.
