White composite fillings and resurfacing of old restorations
A composite filling is a tooth-coloured plastic and glass mixture used to restore decayed teeth. Composite restorations are also used to improve your smile by changing the colour of your teeth or reshaping disfigured teeth.
Composites improve the look of your teeth, as dentists can blend shades to create a colour nearly identical to that of your own actual tooth. The composite bonds to it to support the remaining tooth structure, which helps prevent breakage and insulate the tooth from excessive temperature changes.
After receiving a composite restoration, your tooth may be sensitive for a while. The shade can change slightly over time if you drink tea, coffee or eat staining foods. Although composites tend to wear out sooner than silver fillings in larger cavities, they hold up just as well in small cavities.
