Tooth Stain Colors Explained: What Yellow, Gray, and Purple Teeth Really Mean
Did you know the color of your teeth can reveal more than just your brushing habits? It can reflect what you eat and drink, the substances you use—and sometimes even hint at an underlying health condition.
But before diving into what each tooth stain color means, let’s first understand the difference between the two main types of tooth discoloration: intrinsic and extrinsic stains.
Intrinsic v.s. Extrinsic Stains
Intrinsic stains occur when the inner layer of the teeth—called dentin—changes color. These stains are harder to remove and are commonly caused by aging, overexposure to fluoride, certain medications, or dental trauma.
Extrinsic stains, on the other hand, affect the outer layer of your teeth—called enamel. They are typically more temporary than intrinsic ones. Extrinsic stains are usually caused by consuming tooth-staining foods and drinks, as well as using tobacco products.

What Do Tooth Colors Reveal?
- Yellow - Often caused by dark-colored foods and drinks, or plaque buildup due to poor oral hygiene.
- Brown - Typically from smoking or chewing tobacco; may also indicate tooth decay if accompanied by pits or roughness.
- Purple - Common among frequent wine drinkers due to deeply pigmented tannins.
- Gray - May signal a dead nerve, often the result of dental trauma.
- White flecks - Suggest dental fluorosis, usually from excessive fluoride intake during childhood.
-
Black Spots - Often a sign of advanced tooth decay or underlying cavities.

Can You Reverse or Remove Tooth Discoloration?
Yes—and no. It depends on whether the stain is extrinsic (surface-level) or intrinsic (deep within the tooth).
Surface stains are usually reversible with proper oral care and whitening treatments—even with at-home teeth whitening kits! In contrast, deep-seated tooth discoloration may require the best teeth whitening kit, plus a few visits to the dentist to fully clear it up for severe discoloration caused by dental trauma or medications.
How to Get Rid of Tooth Discoloration
Intrinsic and extrinsic stains can be treated with either at-home whitening treatments or professional in-office procedures, depending on severity.
At-home Whitening
Maintain oral hygiene by brushing, flossing, and using fluoride toothpaste. You can also use professional-grade whitening treatments, such as:
-
Option #1: ClearClub’s Whitening Kit
Designed to treat stains with three strength levels—10%, 20%, and 30%. It also comes with a personalized mouthguard for better whitening gel contact.
-
Option #2: ClearClub’s Cleaning + Whitening Foam
A milder variant with a 3% whitening strength (compared to our standard 10% gel). This fresh mint-flavored whitening foam is perfect for whitening sensitive teeth.
Reduce staining by limiting certain foods and drinks, rinsing after consumption, and staying hydrated. Avoid smoking and visit your dentist regularly for cleanings and checkups.

In-office Whitening
For deep, stubborn stains—especially intrinsic discoloration caused by trauma or medication—professional whitening may be the best route. However, this option is often more expensive and should be reserved for cases that don't respond to OTC or at-home treatments.
