Causes of Brown Spots on Teeth

Posted on 7/24/2023 by OM
Causes of Brown Spots on TeethBrown spots, otherwise called staining, are a discoloration of the tooth's enamel and rarely are a cause of medical concern. The brown spots can be prevented by avoiding some lifestyle habits and can also be corrected using various home remedies or seeking professional assistance.


Nicotine is usually found in tobacco products. Regular smoking or use of tobacco products leads to staining of your tooth's enamel, which can be hard to correct. This is because nicotine combines with your saliva, making staining that coats the teeth. These spots usually range from yellow to brown.

Plaque and tartar

Plaque is formed when bacteria in your mouth combine with saliva to form a sticky substance that adheres to the tooth's enamel. When plaque is not regularly cleaned, it hardens to become tartar, a permanent substance that can only be cleaned off professionally.

Enamel Hypoplasia

Enamel Hypoplasia is a condition in which the enamel does not completely develop and remains thin and weak. Enamel hypoplasia normally happens due to insufficient nutrients responsible for strengthening teeth, malnutrition during the mother's pregnancy, and viral and bacterial infections.


Fluorosis caused by too much fluoride causes teeth discoloration. Fluorosis only affects the tooth enamel and is generally harmless. It affects children below the age of eight.

Tooth Decay

When bacteria in the mouth eat ingested sugar, they form acids that eat away at the enamel, gradually weakening it and digging a hole into the enamel. When bacteria get into these holes, they cause tooth decay. Tooth decay can be fairly painful as it exposes nerve endings which become sensitive when exposed to hot or cold foods and drinks.

Dark-colored Foods and Drinks

Regular intake of dark-colored foodstuffs like coffee and wine leads to discoloration of the tooth enamel. When proper care is neglected, these stains become permanent.
