Not many years ago, metal fillings were the most popular option for treating cavities. The fillings were strong and durable, and in most cases, held up admirably under the pressures of biting and chewing. Now, however, more patients and dentists are choosing tooth-colored fillings made from biocompatible composite resin over the more traditional metal option. The benefits of tooth-colored fillings are many, and you don’t have to look far to find reasons why they’re better than their metal counterparts.
Composite Resin Looks Better
Composite resin is a mixture of finely ground acrylic and quartz-like particles that is applied to the tooth as a liquid. The most noticeable benefit to composite resin is its appearance; unlike metal, the resin can be custom-tinted to match your tooth’s exact color and shade. If you need to treat a cavity, then a tooth-colored filling will help you retain your smile’s natural beauty while simultaneously saving your tooth from decay.
Tooth-Colored Fillings Work Better
One of the more long-term benefits of tooth-colored fillings is the resin’s ability to adhere to your healthy tooth structure. After a cavity, or hole in your tooth, is cleaned of bacteria and decay, your dentist can apply the liquid resin so that it conforms to the cavity’s shape. The material can also be bonded to the tooth’s structure to create a tight seal against infectious oral bacteria. Because metal cannot bond to your tooth as strongly, a tooth-colored filling offers a better chance at preventing oral bacteria from re-entering the cavity and once again infecting the tooth.
