One thing I was wrong about: I thought that my teeth grinding had stopped but realized that it hasn't stopped (even though I'm no longer taking perphenazine, which made me start grinding in the first place). Do you know of any method to stop teeth grinding? I grind them mainly at night (last night I must have been grinding them because today I have a very painful sore on the side of my tongue). So, do you know any way to stop teeth grinding (and also a way to relieve/heal a sore on the tongue)?
