What Makes Teeth Turn Yellow and Dull?

Foods and Beverages

The number one culprit of teeth discoloration is the foods and beverages you have. Highly pigmented foods and beverages such as tea, soda, pomegranates, and blackberries can easily stain your teeth. Additionally, if you’re fond of drinking red wine or coffee, make sure you take the necessary steps to clean your teeth as soon as possible to avoid brown spots.


Enamel is the outer, protective layer of your teeth. Although it is considered one of the hardest parts of the body, it will eventually wear down. Once germs and bacteria penetrate the enamel and wear it away, the underlying dentin will be exposed. The exposure of dentin will soon result in an intrinsic stain which can no longer be removed by a mere surface whitening technique.

Dental Materials

Although it may seem implausible, there is a possibility that dental treatments can lead to discolored teeth. For example, a conventional metal filling can make your teeth appear dull and gray. However, most cosmetic dentists now use composite resin so the rest of your teeth will not be affected.


Antibiotics like tetracycline and doxycycline can cause intrinsic discoloration. Similarly, other medications such as antipsychotics, antihistamines, and blood pressure medications can also lead to teeth discoloration.


Smoking cigarettes or tobacco causes several dental concerns, including teeth discoloration. If you have this habit, you may want to consider putting a stop to smoking if you’re planning to get your teeth whitened. Your money will surely go to waste if you continue smoking after your treatment.
