A composite restoration is a synthetic resin used to restore damaged teeth. Initially unpopular, advances in technology over the past few decades have led to composite restorations being one of the most reliable and aesthetically pleasing restorative procedures. Further, composite restorations are incredibly versatile: they can be used to fill gaps, improve the shape of a tooth, hide stains, repair broken teeth, or cover areas of extreme hot or cold sensitivity. One aspect of composite restorations which has led to an increase in their popularity is their appearance—because they can be made from resins that mimic many different tooth colors, they look exceptionally natural within your mouth. They are even sometimes used to cover up previous amalgam restorations.
One disadvantage of composite restorations is they wear more easily than silver fillings. However, proper dental care both at home and through regular checkups can greatly increase the lifespan of your restoration.
