If you’ve had fillings in the past, you’ve probably had dark, metal fillings— called amalgams—used to fill cavities. Amalgams are effective, but can release harmful mercury into your system. They expand and contract with heat and cold over time and can deteriorate. At Long Grove Dental Studio, Dr. DeMars uses tooth-colored fillings made of a composite resin that chemically bonds to your teeth for strong, durable restorations! Wouldn’t it be great to laugh and show nothing but beautiful white teeth?
