Good diabetic control, no smoking, and removing and cleaning dentures daily can help prevent thrush. Dry Mouth Dry mouth is often a symptom of undetected diabetes and can cause more than just an uncomfortable feeling in your mouth. Dry mouth can cause soreness, ulcers, infections, and tooth decay. The dryness means that you don't have enough saliva, the mouth's natural protective fluid. Saliva helps control the growth of germs that cause tooth decay and other oral infections.
Saliva washes away sticky foods that help form plaque and strengthens teeth with minerals.
One of the major causes of dry mouth is medication. If you are taking medications, tell your doctor or dentist if your mouth feels dry. Good blood glucose control can help prevent or relieve dry mouth caused by diabetes. Keep Your Teeth Serious periodontal disease not only can cause tooth loss, but can also cause changes in the shape of bone and gum tissue. The gum becomes uneven, and dentures may not fit well.
