Dr. Tau Explains Everything You Need to Know About Tooth Stains

Dr. Tau Explains Everything You Need to Know About Tooth Stains

Teeth stain for many reasons. Sometimes, you don’t have to do anything to get stains on your teeth-they just kind of appear. As you get older, your teeth can develop stains from years of accumulated food and drink residue, leaving you unhappy with the appearance of your smile. Other factors, such as medication and tobacco products can also lead to discolored teeth. Philadelphia, PA dentist Dr. Len Tau uses KoR Whitening to remove even the toughest stains. Professional tooth whitening can dramatically enhance the appearance of your smile, causing you to feel more confident.

Schedule your tooth whitening appointment with Philadelphia, PA dentist Dr. Tau today to eliminate those hard to remove tooth stains. Call 215-584-4452.

Types of Stains

There are two main types of tooth stains: intrinsic and extrinsic. Intrinsic stains are hard to remove on your own, while store bought products can reduce the appearance of extrinsic stains.

Intrinsic Stains

As the name suggests, these stains occur deep within the structure of your tooth. Intrinsic stains affect the dentin, which is a sensitive tissue found below tooth enamel, on the inside of your tooth. These stains were once thought to be impossible to remove; however with KoR Deep Bleaching, Dr. Tau can easily eliminate these stains. Intrinsic stains are often caused by tetracycline exposure. Tetracycline is found in antibiotics that are often used to treat a variety of bacterial infections. These hard to remove stains can also be the result of physical tooth trauma, such as a sports injury to the mouth, or an impact from a bike accident.

Extrinsic Stains

Extrinsic stains are easier to remove from tooth enamel. These stains are harder to avoid because they can easily appear due to consuming staining foods and drinks. Red wine, coffee, tea, and soda are common causes of extrinsic stains. These beverages are dark in color; therefore they can leave lines and pigment stains on tooth enamel. Consuming red pasta sauces and dark berries can also result in extrinsic staining.

Store bought tooth-whitening products, such as whitening toothpastes and mouthwashes can reduce the negative appearance of extrinsic stains. These products work to gradually lift the topical stains from your tooth enamel, improving the color of your teeth in the process. For more profound, longer lasting results, it’s important to seek out professional tooth whitening from Philadelphia dentist, Dr. Tau.


Aging is a common factor for discolored smiles. As you get older, your dentin darkens and tooth enamel thins. These events cause your teeth to stain more easily. Younger teeth are easier to whiten for this exact reason. Dr. Tau can brighten up your smile with tooth whitening, but if you’re still unhappy with your smile after receiving whitening treatment, he can recommend porcelain veneers, dental crowns, or bonding to further enhance that state of your smile.

Professional Tooth Whitening

Dr. Tau uses KoR Whitening to permanently whiten the appearance of teeth by eliminating unattractive stains. This type of professional tooth whitening is the most effective and reliable form, removing stains that were once thought to be impossible to eliminate. KoR Deep Bleaching seals the whitening ingredients inside the tray, so that gel doesn’t seep into your mouth while wearing them. This prevents the whitener from being diluted by saliva and reduces sensitivity to your teeth and gums. Dr. Tau will recommend that you wear your whitening trays every night for two weeks to receive the most beneficial results.

KoR Whitening differs from other tooth whitening techniques because it reestablishes your teeth’s ability to absorb oxygen. The deep bleaching gel used in KoR Whitening works hard to dissolve the molecular component of stains, completely removing them, and leaving you with a radiant smile. Most patients experience little or no tooth sensitivity with KoR professional whitening.
