A composite filling or white filling is a tooth-colored plastic and glass mixture used to restore decayed teeth. Composites are also used for cosmetic improvements of the smile by changing the color of the teeth or reshaping disfigured teeth.
Bonding can help restore teeth that have spaces, or repair teeth that are chipped. In this procedure, the tooth's enamel is lightly etched, then covered with an adhesive that is cured with an ultraviolet light. Then, to the surface of the tooth, we place a soft composite resin and mold the resin into a shape that is desired. The resin is hardened and bonded to the tooth with an ultraviolet light source. The new material is then shaped and polished and most times blends with the existing color of the tooth. Bonding is painless and typically anesthesia-free, plus you get immediate results with just one office visit. But bonding only lasts for a limited time, and easily chips or stains.
WHAT ARE THE ADVANTAGES OF COMPOSITES?
Aesthetics are the main advantage of composites, since dentists can blend shades to create a color nearly identical to that of the actual tooth. Composites bond to the tooth to support the remaining tooth structure, which helps to prevent breakage and insulate the tooth from excessive temperature changes.
WHAT ARE THE DISADVANTAGES?
After receiving a composite, a patient may experience postoperative sensitivity. Also, the shade of the composite can change slightly if the patient drinks tea, coffee or other staining foods.
