Got a cavity?
A filling is the usual solution.
Fillings are used to replace missing tooth structure after a cavity is removed. Sometimes a cavity forms around an old filling and the original filling and surrounding decay are removed and replaced with a new filling. This is called recurrent decay. Fillings are tooth colored and blend very nicely with your existing tooth. Occasionally an amalgam (silver) filling may be recommended but you and your doctor can determine the best solution for your tooth together. It makes sense to treat cavities as soon as they are detected to prevent the need for a very large filling, a crown, or possibly needing a root canal. Also, many times small cavities can be treated without needing to get numb!
