Dental fillings help to restore a tooth that has been damaged by bacteria or decay. Fillings are used to seal the affected area, and this helps to keep bacteria out. The filling is used to prevent further decay or deterioration. Tooth colored fillings are made of a material that blends in with your natural tooth color. This type of filling is effective, and does not stand out like other filling materials. Many patients choose this type of filling because they would like their filling to blend in with their natural teeth. Tooth colored fillings are durable and long lasting.
