Brushing, flossing, and general regular cleanings are what you think is necessary for a perfect set of healthy teeth, which is true. But one more thing is the fact you can’t deny is that even after performing every step religiously, there is still room for error. You may develop issues like discolorations, cavities, etc. In this blog, we have discussed why a black spot on a tooth occurs even after good hygiene.

Firstly, you need to know what the black dot present on your tooth is so that a treatment plan can be set according to it. Although you might think it is possible, but it is better to get that dark spot on the tooth checked by a professional.

Black Spot On Tooth Is It Cavity vs. Stain?

You might have confusion regarding the appearance of the black spots on the tooth, whether the little black spot you see on the teeth is a cavity or stain. But what do cavities look like? How do we distinguish between them?

Discoloration or stain on teeth is a layer of pigment on the outer side of the enamel. The most effective entity in this is the food we eat. Some of the common staining contents are present in tea, wine, coffee etc.

The most important thing to realize here is that staining covers the whole tooth or most part of it and is on the surface.

On the other hand, if we talk about cavities, they hit the inner deeper layers of the teeth. They start off as a little black spot on the tooth, and then it seeps inside. Sensitivity is the marker that indicates the presence of a cavity on the tooth. If a sharp zap goes through your mouth upon eating anything hot or cold, the black spot you see on the tooth or near your gum is a cavity.

Reasons for Appearance of Black Spots on Teeth

  • Calcified plaque is a hard substance that makes the teeth look brown or yellow and then goes dark. If black tarter begins appearing near the gum line, you must resort to a dentist for its immediate removal.
  • Cavities are further complications of a plaque that was not removed, turning it brown or black spot-like. The decay area of the tooth under the surface will darken as it starts dying, resulting in discoloration.
  • Apart from the issues mostly due to negligence, aging is a natural phenomenon and another culprit for discolored teeth. The enamel starts deteriorating as we grow old, exposing the lower laying layers of dentin showing yellow or brown spots.
  • One of the diseases that affect the mouth is celiac disease which prevents enamel from developing resulting in either translucent enamel or white, yellow or brown spots.
  • Fluorosis is the excess fluoride intake that causes brown or black pits on the surface of the teeth.


Be it cavity vs. stain, black, or any kind of spots on teeth, there is always a method to fix it. Methods such as filling, root canal, or crown placement are involved if you have cavities.
