My dentist said I had a suspicious looking area on the chewing surface of my tooth that may be a cavity. What is the chance of this spot turning into a cavity?

A recent study on this question shows that the chance of this spot turning into a cavity is rare. However, this assumes that the patient has reasonably good oral hygiene habits and is not overloading his or her diet with sugared food or drink. My recommendation is to always monitor suspicious looking areas and concentrate efforts on preventing this spot from turning into a cavity by stressing the importance of good home care and reducing a person's exposure to sugar.
