Hi Lola2 I have a small mouth & night guards come in different sizes. Most drug stores carry them. They help keep your bite in place & with bruxism. It's worth a try. There are several explanations stated above. Some have directions to boil water so they conform to your bite. You could probably ask the pharmacist and explain your situation & they may be able to offer suggestions on which would be best for your situation. I hope this helps. 🤞🤞🤞. I hope this will resolve your issues. God bless & may you find relief 🙏 & a great night's sleep.❤

I have the dryness in the mouth all the time. Thought it was my Tylenol causing it, BTW everybody, hope you don't mind me being on this thread. My spondylitis is not "NR". It's very visible on x-rays and CTs.

Hi patty Lyn, I haven't tried that but what is a "night guard"? Thank you for your response. It really hurts enough to wake me up. Then I feel it during the day as if I have a sore on the back of my tongue, it's sensitive.

I have had this happen. The first few times it woke me and I was afraid to go back to sleep. Does it feel like you jaw snap shut very suddenly? That is how it happens with me. I’ll be asleep and it’s like my jaw slams shut. It’s very disturbing.
I agree with the night or mouth guards. I believe that may help you.

There are over the counter mouth guards at Walmart. About $20. I started having TMJ-better issues recently. I didn't like the mouth guard, it didn't fit right. But I have found if I sleep in the recliner I don't wake up with my jaw popping.
