Stacy Wiegman, PharmD, Pharmacy, answeredExtrinsic stains refer to those stains on the outer layer of teeth, or on the enamel. They generally give a yellowish tint to your teeth. Extrinsic staining is easier to remove than intrinsic staining. Over-the-counter tooth whiteners are usually enough to treat extrinsic staining on your teeth.
American Dental Association answeredExtrinsic stains on the teeth are those that occur on the surface of the teeth. If you are concerned about stains on your teeth, talk to your dentist first. He or she can help determine if what you're eating or drinking is causing the extrinsic staining and can help remove them either by brushing with whitening toothpaste or by professional cleaning or whitening.
Extrinsic stains yellow the surface of your teeth, and can be caused by eating certain foods as well as smoking cigarettes or drinking coffee. These stains can be removed or made less noticeable, either by brushing the stains well with a good toothbrush or trying an over-the-counter tooth whitening product.

Extrinsic stains are stains on the outer surface of the teeth. They can be removed by a dentist or dental hygienist. Drinking a lot of tea, coffee, and colas can stain the teeth. Smoking also stains the teeth. Intrinsic stains are stains on the inside of the tooth. Tooth whitening may help lighten these stains. Whitening does not remove extrinsic stains. Your dentist can best advise as to the type of treatment to remove stains from your teeth.
Jonathan B. Levine, DMD, Dentistry, answeredExtrinsic teeth staining happens when highly pigmented foods linger on the tooth for a lengthy period of time and ultimately find their way into the superficial layers of the enamel. These stains are much easier to manage than the intrinsic ones, and simply becoming aware of when you're eating or drinking staining foods is a great first step.
