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 constnat stress of chewing. They can be used on either front or back teeth.
Tooth colored composite fillings are chemically bonded to teeth. For this reason, the placement of white fillings does not always require numbing of the area being restored. Numbing (anesthetizing) the area is often required if the tooth decay has progressed beneath the enamel layer and into the underlying dentin layer which surrounds the nerve of the tooth. Once decay is removed, the tooth is cleaned and a primer (weak acid) is applied to the area being restored. The primer opens the pores in the enamel and dentin. A bonding agent is then flowed into the open pores and cured. Curing prepares the bonding agent to adhere to the tooth colored filling material. The filling material is then placed inside the tooth. After shaping the tooth colored filling material to resemble the natural anatomy of the tooth it is hardened by curing with a strong curing light Once the white filling hardens, the bite will be checked to make sure the teeth fit together properly. If the tooth filling extends into the space between the teeth, Dr. Aaron or Dr. Matt will also make sure that floss can go between those teeth properly. Adjustments will be made if necessary followed by smoothing and polishing the new filling.
