We remove tooth decay, fill cavities, and repair fractured teeth. We also diagnose and treat problems with patients' teeth, gums, and related parts of the mouth. We provide advice and instruction on taking care of the teeth and gums and on diet choices that affect oral health. We also do cosmetic dentistry. Oral hygiene is the practice of keeping one's mouth clean and free of disease and other problems by regular brushing of the teeth and cleaning between the teeth.
