Dental fillings prevent further tooth decay by blocking the entry of bacteria. This procedure is a common cavity treatment and also performed on cracked teeth, worn down teeth, and broken teeth. Bunker Hill Dentistry is a mercury free practice and we do not use silver (amalgam) for dental fillings at all. Silver filling can contain up to 50% mercury; the results are not just ugly, they are toxic. What Happens During A Dental Filling? First the affected area is numbed using a topical anesthetic. Dr. Le then cleans the tooth, removing all existing bacteria and decay. Once the preparations are complete, Dr. Le will use a composite material to fill the spaces created. These additions are dried instantly using a handheld tool. When all teeth have been treated, the bite is tested multiple times to ensure overall comfort. How Do I Know If I Need Dental Fillings? Regular dental visits are essential to detect signs of decay before your teeth are damaged beyond repair. It is at these meetings that Dr. Le will recommend fillings if they are necessary. If you feel pain, increased sensitivity, or have another cause for concern don’t hesitate to schedule an appointment at Bunker Hill Dentistry.
