A Cosmetic Dentist In Downtown La Can Restore Your Smile With Composite Bonded Fillings

A beautiful smile is important to your self- esteem and can have a great effect on your personal

, social, and professional life. Everyone wants the most attractive smile possible. Your smile is the first thing people notice about you and the last thing they forget. Unfortunately, if you have silver amalgam fillings, your smile isn't as appealing as it could be. Don't despair; those ugly grey spots in your teeth don't have to be there. With modern technology, a beautiful alternative is available. Many people have replaced their silver amalgam fillings with tooth-colored, natural looking, composite bonded fillings.

Composite fillings are not only aesthetically superior, they consist of a resin-based matrix and glass or quartz particles so there are no mercury or other metals in them. The safety of the mercury in amalgam fillings is a hotly debated issue. By weight, amalgam is 50 percent mercury and the remainder is silver, copper, and tin. To date, research has not found any risk associated with the mercury in amalgam fillings. However, leftover amalgam was declared a hazardous substance by the EPA in 1989. In addition, the labels on containers of dental amalgam carry the warning "contains metallic mercury poison" above a skull and crossbones symbol. Many people feel that if the EPA says amalgam is too toxic to be buried in the earth or disposed of in the landfill, they don't want it in their mouth.

Composite bonded fillings have other benefits in addition to superior aesthetics and being mercury free. Amalgam fillings require the removal of more of the natural tooth to form the undercut that holds the filling in place. The amalgam is wedged into the hollow, providing no more than a plug for the hole in your tooth. The extensive preparation weakens the tooth structure and can cause the tooth to crack or break under pressure. Composite fillings actually bond to the prepared tooth, therefore strengthening the tooth structure. White fillings contain no metal, so they are a perfect solution for people with metal allergies. The resin sets up quickly and is hard before the patient leaves the dentists office. They are able to eat whenever they choose to.

Placing a composite filling may take a little longer than amalgam because the tooth has to be kept perfectly dry, but the procedure is very similar. A local anesthetic is administered so you will be comfortably numb. The tooth is cleaned of plaque, tartar, and debris so the resin can bond tightly. Any decay or compromised tooth structure is removed and the shade of the resin is matched to the color of the tooth. An adhesive is applied and then several layers of the composite are added. Once in place the filling is hardened by a special light for about 60 seconds. Your new fillings require no special care, just good oral hygiene, and regular visits to your downtown LA dentist.
