[|Human|] I went to the dentist a few months ago to get a retainer (the clear plastic one) and it creates big ulcers so bad that i cant put it back in. So after a few month i went back and hes letting me try again, but the ulcer has come back in the exact same spot. Is this because of the retainer?
[|AI|]  Hello, Welcome Thanks for consulting Chat Doctor I have gone through your query, as you are wearing retainer and ulcer develops on same point again, yes ulcer can be due to retainer may be due to sharp edges or any sharp point on retainer causing ulcer.  Don't worry you go to dentist and get trimming of that sharp point or edge are there.  You can apply ointment McCoppin or Pans oral on ulcer twice daily for healing.  Take one capsule vitamin B complex once daily for 7 days. Hope this will help you. Wishing you good health.
