Tooth decay can detract from the appearance of your smile. But beyond that, a cavity can be painful and can leave your tooth vulnerable to infection. If a cavity is not treated, you could even risk losing your tooth. At Oaks Family Dental Associates, our dentist can use composite, or tooth-colored, fillings to repair the damage done by decay. For your appointment with Dr. Elizabeth Brennan for a composite dental filling in Oaks, Pennsylvania, call our office at 610-666-5118.
