I'm on Accutane for the third time in my life. Never had any pain or issues with my teeth. Your lips will be dry and may crack some though. I use a combination of Vaseline and Burts Bees lip balm to keep my lips from getting too dry. It works well for me. Good luck!

Nope teeth will not be affected just dry lips.

I had (lingual) braces while on Accutane. No issues here.
