Tooth Colored Fillings
Composite resins, or tooth-colored fillings, provide good durability and resistance to fracture in small- to mid-size fillings that need to withstand moderate pressure from the constant stress of chewing. Unlike amalgam or silver fillings, composite fillings are mercury-free. They can be used on either front or back teeth. They are a good choice for people who prefer that their fillings look more natural. Tooth-colored fillings are now used more often than amalgam or gold fillings, probably due to cosmetics. In a society focused on a white, bright smile, people tend to want fillings that blend with the natural color of their teeth.
Ultimately, the best dental filling is no dental filling. Prevention is the best medicine. You can dramatically decrease your risk of cavities and other dental diseases simply by:
brushing your teeth twice a day with fluoride toothpaste
eating a balanced diet
visiting the dentist regularly.
