Extrinsic stains are those on the surface of the teeth which are caused by what the patient consumes over a long time—dark colas and red wine, smoke, and coffee, for example. These are easy to remove with bleach. But intrinsic stains are caused by something affecting the dental pulp. This could be overexposure to fluoride or tetracycline antibiotics during the tooth’s formation, but if the stain shows up after the tooth’s development, it is probably due to inflamed tissue.
Dental pulp becomes inflamed due to trauma or infection, and it will not heal on its own. While bonding could conceal an intrinsic stain, an infection threatens the patient’s well-being, and possibly their life, so the pulp must be removed through a root canal. Once the tooth has been filled and sealed, our doctors can determine whether it needs to be bonded or given a new crown.
