What would be the cause of bleeding under your top dentures?
even though i am only 16 i know all about dentures. i have both upper and lower. the bleeding is most likely caused from an irritation from the dentures rubbing or pressing against your gums. their might be a shape edge too. you should bring them to the dentist and they can fix them easily. it doesn't take long either.
Reply:your gums are irritated and you need to rest them without the dentures. also, i hope you are using a good seal for them.
