White, or composite dental fillings, are closely matched to the colour of your teeth, and can be prepared and placed in one visit. Composite dental fillings can replace decayed teeth, a dental cavity, or repair a damaged tooth.
White dental fillings are most commonly used for:
After removing the decayed portion of the tooth, A very mild acid solution is used to etch the tooth surface. Afterwards, a bonding agent is brushed onto the prepared tooth, followed by several thin layers of the white, tooth-colored composite. Once placed, the material is chemically hardened, or cured with a special hardening light, and then polished.
White dental fillings are highly preferred to mercury amalgam, as they are stronger, look natural, and are safer for your overall health. Many people have mercury amalgam fillings in their mouth from previous dental work, which contain mercury. Aside from potential health risks, they do not look natural, and can lead to weakened or cracked teeth.
