If you have denture ulcerations, there are a few things you can do to treat them.
Rinse your mouth with warm salt water several times a day. You can also try using 3% hydrogen peroxide.
If the ulceration is painful, you can take over-the-counter pain medication such as ibuprofen.
If the ulceration does not improve within a few days, or if it gets worse, you should see your dentist. They can prescribe a stronger medication to help heal the ulceration. In some cases, they may also need to adjust your dentures.
Ulcerations can be painful and annoying, but with proper care, they will usually heal within a week or two. If you have any questions or concerns about your ulceration, be sure to talk to your dentist.
