Stained teeth are a popular problem in dentistry, to the point where even toothpaste companies are trying to find the perfect whitening formula. But not all dental stains are exactly alike, and depending on the reason for your tarnished coloration, you might need more than at-home oral hygiene to brighten your smile. Keep reading to learn all about tooth stains and how your dentist can personalize your treatment plan!

Extrinsic Dental Staining

“Extrinsic” typically refers to something that is “outside” or “external,” so it makes sense that this type of stain affects the outermost layer of your pearly whites (a.k.a. enamel). In this case, pigments from darkly colored foods and drinks, like coffee, tea, and tomato sauce, are trapped just on the surface of your enamel. This makes them easier to remove, and extrinsic yellowing usually responds well to professional teeth whitening treatments.

Intrinsic Dental Staining

“Intrinsic” is the opposite of “extrinsic.” This type of dental discoloration involves pigments that have slipped past the pours in your enamel and are settled deeper inside your tooth. Much like how you might have to use a special cleaner to remove stains from a porous countertop, intrinsic yellowing can’t always be eliminated with your dentist’s whitening agents. When the stains are severe, it’s often better to conceal the blemishing with dental bonding or porcelain veneers.

Natural Tarnishing

Both extrinsic and intrinsic staining can occur naturally over time. The inner layers of your teeth simply turn more yellow as you age, and daily wear and tear from chewing thins out the enamel, making it easier for pigments to become trapped in your smile. Depending on your situation, your dentist may be able to use a combination of cosmetic treatments to enhance your pearly whites.

Ways Your Dentist Can Brighten Your Smile

As you can already see, your dentist has many different ways of brightening up a smile. After identifying the type of staining that’s tarnishing your teeth during a consultation and exam, they’ll be able to personalize your treatment plan to address your unique grin. Whether it means removing stains directly with teeth whitening, concealing deep discoloration with bonding or veneers, or combining treatments into a smile makeover, your dentist will help you reach your cosmetic goals!
