Composite fillings are a dental treatment used to repair teeth affected by decay, cracks, or minor damage. They are often referred to as “bonding”. They are made from a tooth-colored blend of plastic and glass that restores both the function and appearance of the tooth. In addition to treating cavities, composite fillings can also be used for cosmetic purposes, such as improving discoloration or reshaping teeth that are chipped or uneven.
Dental bonding or Filling is a procedure that uses a tooth-colored composite resin material to repair areas of a tooth affected by decay. Years ago, cavities were most commonly treated with amalgam, often called “silver fillings.” While those restorations are still safe and effective, modern dentistry has largely shifted toward composite materials for treating cavities.
Composite fillings are considered more conservative because they require removing less natural tooth structure. Preserving more of the tooth helps maintain its strength and overall health. Another major advantage of composites is their appearance—they are designed to closely match the natural color of your teeth, making them a more aesthetic option compared to silver fillings.
In addition to treating cavities, bonding can also be used to repair minor chips, cracks, or imperfections, especially on front teeth, improving both function and appearance.
Patients often ask whether their silver fillings should be replaced. If an existing amalgam filling is intact, free of decay, and not causing any issues, there is no medical need to remove it. However, if you are dissatisfied with how it looks, it can be replaced with a composite filling for cosmetic reasons alone.
