Tooth decay damages the tooth surface. Early mineral loss may respond to preventive care, while a cavity is a hole that usually needs a restoration. A tooth can have decay without hurting.
An examination and X-rays when needed help determine how much tooth structure is affected. Deep decay may need additional care, including discussion of root canal treatment or referral.
