As an expert in cosmetic dentistry, Dr. Suzanne Haeri offers safe, effective, and fast teeth whitening. But although bleaching is a valuable tool for combatting stains on the outside of teeth, there are some stains that may be too deep for it to reach. These are intrinsic stains, and they require a different approach.
Intrinsic stains have two causes: absorption of dark molecules during the tooth’s formation, and inflammation. The molecules are usually from tetracycline antibiotics or too much fluoride. Neither of these is harmful and the affected teeth can be covered with veneers. But when a tooth suffers trauma or infection, the patient is at risk. Dental infections will not get better on their own, and they cause severe tooth aches and can progress to the point of endangering the patient’s life. A root canal is necessary to remove the infected matter and the tooth can be reshaped or concealed afterward. Depending on how much material is removed, a new, natural-colored crown may be needed.
