I wear dentures and recently i have these white painful blisters on the top and bottom of my gums. what is it and what do i do?

See your dentist: Don't sleep with your dentures. Clean them with a stiff tooth brush and then commercial cleaner. See your dentist to determine if the problem is being caused by the denture or something else. Dentures should be checked and your mouth checked for cancer, infections, denture sores ect. At least once a year.

Depends: Could possibly be from pressure of ill fitting dentures or possibly even a reaction to the denture, adhesive or even a yeast infection in the denture plastic. See your dentist to have it checks out.

Ulcerations ?: Depending on how well-fitting your dentures are, these could simply be ulcerations caused by the dentures moving. It the dentures are loose, they may need relined, or may need to be remade altogether. Other causes could be due to medications or changes in diet. Make an appointment with your dentist to take a close look. Keep smiling !

Fungal infection: These might be a fungal infection. Please have them checked out by a dentist. Also, make sure that you clean your dentures everyday and try not to sleep with them.

See your dentist : What you describe sounds like a common fungal infection that many denture wearers get. If your dentist confirms this diagnosis he will prescribe anoral anti fungal rinse which will help the problem. He would also have to rule out viral infections. Your dentist could then go over proper oral hygiene and denture cleaning so as to avoid the problem in the future.

See a dentist: I would see a dentist and also place the dentures in some antibacterial cleansers like efferdent plus and let them soak. The first option, though, is get to the dentist to exam.

See your dentist: This could be a fungal infection, or something else. It is probably not sore spots from the dentures, but could be. You need to see your dentist.
