No autoimmune disease. Since there's no cuts to my tongue or cheek the dentists says there's no issue. I can see on my tongue where the teeth irritate it because there's sometimes small red dots or little canker sore type looking bumps but not canker sores. I the crown they put on the top which is the second one and 3000 out of pocket the cusps feel rough to tongue and make it so sore I can't stand it much longer. Wax doesn't stay on the tooth. The bottom tooth that irritates tongue wax helps some which tge dentist thought was odd and not sure why it would help. But it helps because it covers whatever feels sharp to my tongue. I just want my life back to normal. Where I can get through the day with no mouth pain and enjoy life again. I have tried prescription mouthwashes, nerve pills, etc. Putting retainer in or wax helps a little but feels like not enough room for my tongue and the retainer doesn't fit well irritates after awhile and doing that all day is no life. I've had all kinds of bloodwork, mri, endoscopy, colonoscopy, everything. I really think is just a few of these teeth are worn and lack of room they rub my tongue but no one listens or sees it so nothing gets done. My family is tired of listening to me all day talk about the pain and wanting it fixed as it's been over 2 years. I thought maybe it would go away on its own but that isn't going to happen.
