White fillings are known as composite Resin or glass Ionomer Restorations. They are a simple, quick, and non-invasive procedure used to correct minor cosmetic flaws, such as small cracks, chips, worn teeth or unsightly gaps. A malleable tooth coloured resin is applied to the treated area, which is then hardened using a special dental lamp. Once polished the resin is virtually indistinguishable from the surrounding teeth.
