Firstly, not to use it as an excuse or anything but I have ADHD and sometimes I simply can’t bring myself (or just forget) to brush my teeth, sometimes for days. I recently got a job and that’s given me the “drive” to brush my teeth every day. The thing is, every time I brush my teeth I get ulcers in my mouth and tongue the next day. This also happened when I would brush my teeth after a day/a few days of not doing it and went back to being fine when I didn’t brush. I could only assume it was my toothpaste, so I switched from Colgate to sensodyne but it’s still happening. Does anyone know what this is? Is there a certain toothpaste I should try? It’s almost at the point where I’d rather just not brush my teeth… these ulcers are so annoying and painful
