How Teeth Change Color

Teeth discoloration is a common concern that occurs due to a variety of factors, both intrinsic and extrinsic. Intrinsic discoloration originates from within the tooth and is often caused by changes in the dentin or enamel. Factors such as aging, trauma, or exposure to certain medications like tetracycline during tooth development can lead to a yellowish or grayish hue. Genetic factors also play a role, influencing the natural shade of a person’s teeth.

Extrinsic discoloration, on the other hand, occurs on the surface of the tooth enamel. This is typically caused by external factors such as consuming staining substances like coffee, tea, red wine, or tobacco products. Poor oral hygiene can exacerbate these effects, as plaque and tartar buildup make stains harder to remove.

Lifestyle habits and environmental factors also contribute to teeth color changes. For example, excessive fluoride exposure during childhood can result in fluorosis, characterized by white or brown spots on the enamel. Additionally, acidic foods and beverages can erode enamel over time, exposing the darker dentin beneath.

Maintaining good oral hygiene, limiting consumption of staining foods, and seeking professional dental cleanings are key to preventing and addressing discoloration. For more severe cases, cosmetic treatments such as whitening procedures or veneers may be recommended.
