Cavity, or tooth decay: Perhaps the most common cause for a black spot on your molar teeth is tooth decay, or a cavity. A cavity forms when the build-up of plaque, which contains acids, is allowed to erode the surface enamel of a tooth. A hole in the tooth’s protective layer sometimes shows as a black dot.
Why is the root of my tooth dark?
When the blood vessels and nerves die, the root turns dark brown in colour. Particles of this dead root permeate the dentin, and since the dentin is very porous, this causes the dentin to darken in colour as well. Since the enamel is translucent, the colour of the dentin shows through.
Can a dark spot on a tooth not be a cavity?
Dark spots on our teeth need not always be cavities. Naturally occurring dark spots caused by staining of the teeth are a common condition that very often goes undetected. Tooth discoloration is usually present in the very small pits and ridges on the surface of human teeth.
Are brown spots on molars cavities?
Cavities. As previously noted, a brown spot may certainly signal cavities or decay. Foods and beverages that are high in sugar create a plaque that sticks to the surface of the teeth. With time, this plaque and the bacteria it houses can destroy the enamel, causing brown spots.

Do root canals discolor teeth?

How can you tell if its a cavity or stain?
The brown, black, or grey spot on the teeth is a sign of a cavity, while the discoloration of teeth is a stain. A stain is a result of drinks and food and is not sticky. However, the cavity damages the teeth. It provides an ideal environment for bacteria and plaque to grow in the teeth, destroying them.
Does Brown spot mean cavity?
