People who wear dentures can sometimes experience an infection of the mouth called cheilitis, which can cause painful inflammation and cracks at the corners of the mouth. This is often due to an overgrowth of yeast from dentures that fit improperly. Yeast is always present in our mouths, but certain issues can cause it to accumulate and cause infections like cheilitis. It’s important to visit your denturist regularly (at least once a year) so they can make any necessary adjustments to refit your dentures. Be sure to clean your dentures daily and chew on both sides to maintain proper fit.
