Intrinsic tooth stains are stains that are inside the tooth. Some antibiotics such as tetracycline can stain the teeth as they are developing. Most pediatricians avoid these antibiotics in young children. Trauma to a tooth can cause bleeding inside the tooth. This can also lead to intrinsic stains. Your dentist can best advise you as the cause of your stain and recommend treatment. Some intrinsic stains can be removed with whitening while others may require crowns and veneers. Teeth that have stained from internal bleeding may require root canals followed by a whitening procedure.
