There are numerous types of tooth discoloration, including black stains. If you recently noticed dark blemishes in your smile, a dentist can identify the reason for their appearance and treat them as needed. Below, learn more about these black stains to get an idea of what could be causing them.

Causes

Plaque is the sticky biofilm in the mouth that feeds on sugary food particles. It produces acids that lead to decay or cavities, which often cause black stains. These blemishes typically appear as holes or pits, indicating that bacteria has broken down numerous tooth layers. 

Without daily brushing and flossing, plaque builds up along the gumline, as well as between and on your teeth. The biofilm darkens following exposure to certain foods and drinks, including coffee, red wine, and starchy foods.

Black stains can indicate cosmetic issues, such as discoloration from frequent tobacco and nicotine use. Certain medications also affect teeth. For instance, tetracycline antibiotics can lead to brown or black spots. Additional causes include enamel wear that exposes the dentin and old, metal-based dental work, as the material can discolor teeth over time.

Treatment 

Treatment for black stains depends on the cause. If the issue is cosmetic, teeth whitening services combined with healthy habits, such as quitting tobacco, usually suffice. Other discoloration problems necessitate replacing old dental work, filling cavities, or deep-cleaning teeth. Removing plaque and tartar restores the natural tooth color.

Severe discoloration can require dental veneers, which are thin porcelain shells that fit over existing teeth to disguise stains. They also help address other cosmetic issues, such as chipped or worn teeth. Dentists remove small amounts of natural tooth material to ensure the veneers fit comfortably.
