Because tooth-colored fillings do not use metals, they can easily be blended and shaded to match the exact color of your teeth. You’ll never have to worry about a gray sheen or off-color look to your smile.
Additionally, dentists don’t need to buff down enamel to make room for an amalgam filling, similar to a dental crown. With composite resin, they only need to fill the damaged tooth, shape it, and harden the material, allowing you to maintain more of your tooth’s natural structure.
For some, metal fillings cause increased teeth sensitivity. Composite resin doesn’t contract and change shape when exposed to stimuli, so it’s far less likely to cause sensitivity.
