A composite filling is a tooth-coloured plastic and glass mixture used to restore teeth. Composites are also used for cosmetic improvements of the smile by changing the colour of the teeth or reshaping disfigured teeth.
Aesthetics are the main advantage of composites, as we can select a shade that best matched your natural tooth structure. Composites bond to the tooth to support the remaining tooth structure, which helps to prevent breakage and insulate the tooth from excessive temperature changes. Composite fillings require minimal intervention to the tooth structure, relying on chemical rather than mechanical bonding to the tooth.
