Hi all I'm new and been reading on the forum for awhile just never posted. But I am a 25 year old female, I have 3 white patches on the side of the tongue. I had them checked by my Ent and he said it's from my teeth last April and it's now January and they're still there. I saw a nurse practitioner as my doctor wasn't available until May and she said its mostly from clenching of the jaw. I'm just freaking out it might be Cancer or something. I do clench all the time and have annoying extra tooth in the back that could be causing problems. I usually dont get worked up about anything but this is freaking me out! Anyone have any similar situations?
