A filling is most often the final step to bringing a decayed or fractured tooth back to working order. When teeth are decayed, infected or broken, your dentist will use a tooth-coloured composite resin restoration, silver amalgam, or glass ionomer filling to restore the shape and function of the tooth, after removing a decayed or affected area of a tooth.
Why use composite fillings?
Composite fillings bond to the tooth surface securely, and do not expand and contract with temperature changes as metal fillings do. As a result, a composite filling makes for a strong addition to the structure of a tooth. The best part about composite fillings is that they can be matched to the natural colour of your teeth, making them indistinguishable once installed. These fillings are durable and last a long time, but no filling is permanent.
