Black Teeth: Causes, Warning Signs & Treatment Options
San Juan Capistrano, CA
Noticing black teeth or dark spots on your teeth can be alarming. Many people search for “black teeth” because they’re worried about decay, infection, or whether the problem is cosmetic or serious.
Here’s what black teeth can mean, what causes them, and how dentists treat them—before they turn into bigger problems.
What Causes Black Teeth?
Black discoloration on teeth can develop for several reasons. Some are surface-level, while others indicate deeper damage.
Common causes include:
Tooth decay (cavities)
Tartar buildup under the gumline
Dead or dying tooth pulp
Dental trauma
Certain medications or metal fillings
Poor oral hygiene over time
Understanding the cause is key to choosing the right treatment.
Are Black Teeth Always a Sign of Decay?
Not always—but they often are.
Black spots may start as surface staining, but dark brown or black areas are frequently associated with advanced decay or infection, especially if accompanied by pain or sensitivity.
