You should brush your teeth daily with a soft-bristled brush. You might also floss daily to clean between the teeth, although it could be too irritating to your gums.
Your mouth should also be kept moist, both for oral health and for comfort. If a dry mouth is a problem, your doctor can prescribe an artificial saliva or a saliva stimulant. Rinsing your mouth frequently with water, chewing sugarless gum or sucking on ice chips or sugarless candies can also help keep the mouth moist.
