The structure of the tooth can be damaged by decay or a fracture. This damage is repaired by use of filling in the damaged area with a specific material. Spring Mountain Dental offers both white and silver fillings, depending upon the patient’s choice. Silver fillings are more durable and less expensive than white fillings. These are normally used in the back teeth where more force is needed to chew. White fillings are more commonly used in front teeth as they blend in with the natural tooth color.
