What Causes Tooth Discoloration?

Posted on 4/24/2023 by Southern Family Dental Care
What Causes Tooth Discoloration?Tooth discoloration can occur in adults and teens. The color of the discolored teeth can vary from yellowish to brown. If left untreated, discolored teeth can result in tooth decay. It can also affect your smile, making you avoid social occasions. Luckily, there are teeth whitening options that can brighten your smile. However, before the dentist determines a suitable treatment for you, it is vital to know the cause of discoloration. Here are 4 causes of tooth discoloration.

Poor Oral Hygiene

Poor oral hygiene can allow bacteria and food particles to build up in your mouth and around the teeth. Over time, the buildup will turn into plaque and tartar. The bacteria will then consume any sugar in the mouth to produce acid, weakening the enamel. As the enamel wears away, it exposes the yellowish layer of the tooth.

Certain Foods and Beverages

Certain foods and drinks can also affect the color of your teeth. While they are delicious, they can do more harm to your teeth. Items such as red wine and coffee have a high acidity level. For instance, red wine contains tannic acid, which has a staining effect. After some time, the stain may become permanent, especially if you do not implement good dental hygiene.


Tooth discoloration can occur as you age. The aging process contributes to the erosion of the tooth enamel. This exposes the layers of the dentin, which are yellowish in color.

Smoking Tobacco

Tobacco contains nicotine and tar. When these chemicals seep into the tooth enamel, they leave a brown or yellow color on the tooth. In this case, you need to change your lifestyle habits to prevent tooth discoloration. You can also whiten the teeth through dental procedures such as whitening toothpaste, gels, or in-office teeth whitening approaches. Don't live with a smile you're not proud of.
