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. 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.

Composites cost more than amalgam and occasionally are not covered by some insurance plans. Also, no dental filling lasts forever. Some studies show that composite fillings can be less durable and need to be replaced more often than amalgam fillings.

It generally takes longer to place a composite filling than it does for a metal filling. That’s because composite fillings require the tooth be kept clean and dry while the cavity is being filled. 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.

Composite resins, or tooth colored fillings is the primary restorative material used today to restore small to medium sized cavities, defective fillings, or other tooth defects.  Composite filling hold up well against moderate wear and tear and, if placed properly, can last a long time.

Composite filling, because they take longer to place than alloy/silver fillings, cost more.  The placement of composite fillings is more technique than the placement of silver fillings. The tooth must be kept dry and there are multiple etching, priming, and bonding steps during the placement of resins that do not exist with alloys fillings.

Composite resins can be used in both back teeth and front teeth. Because they are tooth colored they blend in excellently with existing tooth structure, and when done well are near invisible to the naked eye.  For this reason, resin fillings are popular with patients conscious of esthetics and a healthy looking smile.
