I had a small amount of my tongue excised for mild to moderate dysplasia, and am now concerned as I sometimes wake up from biting my tongue on either side. I wonder if that caused all my grief and I certainly don't want to go through that again if I can help it. I am trying to contact my dentist to see if I need a mouthgard or something, but I asked him a few years ago when I first noticed this sore and he said it didn't look like I had grinding or sharp teeth. I hope I didn't cause all this from lying on my left side while I was pregnant and chewing on my tongue....although I did find one article that claimed trauma had no correlation to dysplasia...
