Dating back to the earliest days of modern dentistry, cavities were always filled with some blend of metals. These included
silver and even dangerous and hazardous metals like mercury.
It became common practice to to view dark grey areas within someone's mouth when they laughed due to how cavities were filled. Today, however, you can get your cavities filled using much better-looking, aesthetically pleasing methods. Not only are these methods more natural looking, they also provide for better health.
Composite fillings are made from resins that are matched to your tooth's color â€“ so they become invisible when applied. Composite fillings also provide an excellent seal on the affected area, so that tooth decay can be prevented.
Composite fillings tend to be used as an alternative to metal or silver amalgam fillings and are used to treat decay on a portion of a tooth to replace an old silver amalgam filling and to maintain a white smile. Composite fillings are more than just attractive and they have distinct advantages over other types of fillings especially metal ones.
Composite fillings are environmentally non-toxic because they use no mercury. They are stronger because they bond directly to the surface of the tooth. They protect the tooth from fracturing because they don't require the severe â€undercutâ€ (removal of healthy tooth structure) of mercury fillings.
