White fillings, also called “composites” or “bonding,” are a nearly invisible way to repair chipped or broken teeth. It can also be used to fill cavities or close spaces between teeth. It comes in a variety of different shades and colors, so we can match the fillings to the shade of each person’s teeth. Here at Dugas Dental, we use a computerized shade matching machine called a Vita Easy Shade 4.0 to pick the perfect shade.
Unlike metal (amalgam) fillings, which lock in by undercuts, composites adhere to teeth by a special glue called bonding agent. This allows us to place white filling material in conservative, thin layers without having to cut away extra tooth for the undercuts. White fillings do not expand and contract with temperature like metal fillings, so white fillings cause significantly less cracking in teeth.
Although some patients experience a little more post-operative sensitivity with white fillings versus metal fillings, this sensitivity usually resolves in less than a few weeks. At Dugas Dental, we use a specific bonding agent that includes a desensitizing agent to help reduce sensitivity. When done correctly, white fillings are conservative, invisible, and have hardly any post-operative sensitivity.
