Are Brown Spots on Your Teeth the Sign of a Cavity?

Posted on 2/15/2019 by College Hill Dental
Are Brown Spots on Your Teeth the Sign of a Cavity?If you notice brown spots on your teeth, your first thought may be that you have a cavity. This is true – sometimes. Brown spots can signal a few different issues, so it is important that you see us so that we can identify the problem.


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. Fillings or root canal therapy may be recommended in order to treat the problem.

Teeth Stains

In other cases, brown spots are simply caused by stains from the foods and drinks that you consume. Dark-colored drinks like red wine are high in tannic acid, which can stain the enamel. With time, these stains may become permanent, especially if you find it difficult to keep up with a good oral hygiene routine.

Nicotine and tobacco products can also cause brown stains. These substances contain particles that can stick to the tooth enamel, and they can build up. With time, stains can become darker and difficult to remove.

Unfortunately, as we get older, our teeth also go through the aging process. The white enamel will degrade slowly, exposing yellow dentin underneath. This natural process may lead to brown spots and patches of discoloration.

Celiac Disease

People with Celiac disease often have poorly developed enamel. This may lead to brown or yellow spots on the teeth. Unfortunately, the effects are permanent, so dental restorations may be needed in order to cover up the problem.

If you notice brown spots on your teeth, please call our office right away. We'll help to find the source of the problem and will create a successful treatment plan.
