Until recently, silver amalgam was the material most often used to restore decayed portions of your teeth, especially back teeth. Unfortunately, silver fillings can really darken a smile, and amalgam, by its very nature, can cause damage to your tooth in the long run. Amalgam fillings absorb moisture and expand and contract with heat and cold. So, as the filling ages, it can fracture your tooth; we'll then need to place a crown on your tooth to save it. Also, silver fillings often undergo metal fatigue, corroding and leaking over time. This destroys the protective seal of the filling and allows new decay to develop underneath it. This leakage can give a gray appearance to the entire tooth.
New tooth-colored options
Dental research has resulted in the development of new tooth-colored materials that are not only durable and long lasting, but attractive as well. These materials, porcelain and composite resin, provide an attractive, natural look while at the same time restoring strength and durability to your tooth. Both porcelain and composite resin are bonded directly to the tooth, restoring it to near its original strength and function. Both can be custom-colored to precisely match your teeth, so when porcelain or resin fillings are placed, they're extremely natural looking. This can really make a difference in your appearance, especially if the restoration is visible when you smile.
More advantages of white restorations
When we place an amalgam filling, we have to remove extra healthy tooth structure just so the filling will stay in place. When we restore your tooth with composite resin, we need to remove only the decayed portion because the bond anchors the material tightly in place. This means you retain healthier tooth structure. Also, because white fillings are bonded to your tooth, they add strength to the tooth.
