A composite (tooth-colored) filling is used to repair a tooth that is affected by decay, cracks, fractures, etc. The decayed or affected portion of the tooth will be removed and then filled with a composite filling. Composite fillings are widely used today. Because composite fillings are tooth colored, they can be closely matched to the color of existing teeth and are more aesthetically suited for use in front teeth or the more visible areas of your teeth. They are very durable, and will last many years, giving you a long-lasting beautiful smile.
