Composite Fillings

Composite resins, or tooth-colored fillings, provide good durability and resistance to fracture in small- to mid-size fillings that need to withstand moderate pressure from the constant stress of chewing. They can be used on either front or back teeth. The use of composite fillings has become more wide spread because of improved composite resin materials and bonding agents. Tooth-colored fillings are now used more often than amalgam or gold fillings, most likely due to better cosmetics.

How are they placed?

First, all decay has to be removed. Then, the tooth is etched with a weak phosphoric acid solution to create a surface that increases bond strength to the composite resin. Next, the composite resin is placed little by little into the tooth and hardened with a curing light. Last, the composite resin is shaped to fit the bite and polished. It generally takes longer to place a composite filling than it does for a metal filling because composite fillings require the tooth be kept clean and dry while the cavity is being filled.

Ultimately, the best dental filling is no dental filling. Prevention is the best medicine. You can dramatically decrease your risk of cavities and other dental diseases by having a healthy dental routine:

  • brush your teeth twice a day with fluoride toothpaste

  • floss daily

  • have a balanced diet

  • visit the dentist regularly
