The American Dental Association generally advises diabetics not to wear dentures all the time. Thrush, a fungal infection, is a common complication in diabetics wearing dentures.. It appears as red or white patches throughout the mouth and causes a burning feeling and may make it difficult to swallow. It is more likely to happen if you:experience dry mouth, decreased saliva flow, have problems controlling your blood glucose levels, smoke, are taking antibiotics.
Thrush can be diagnosed by either a physician or dentist, and will resolve by taking a prescribed antifungal medication.
