A cavity leaves a small hole in the tooth that needs to be cleaned out and filled. The dentist first removes the decayed part of the tooth. That leaves a clean, healthy space ready to be filled. A tooth-colored composite resin is placed into the space in thin layers. A curing light hardens each layer of the resin. The filling is then shaped and smoothed to match the natural bite. The result is a sealed tooth restored to its normal shape. This video is for general education only. It is not medical or dental advice. Ask your dentist what's right for you.
