If left unaddressed, even a small area of tooth decay can create big problems for your smile. A cavity can become painful, and an infection could lead to swelling and problems that can affect more than just your oral health. At the first indication of a cavity, contact Montgomery Street Dental at 415-398-6344 to schedule an appointment with our dentist. Dr. Alireza Khoshvaghti and our team offer composite dental fillings in San Francisco, California, which can restore not just the health and function but also the appearance of your tooth.
