Culprits Behind Discolored Teeth and How to Combat Them

Discolored teeth affect our beautiful smiles and can cause us to feel embarrassed about the appearance of our teeth. There are numerous reasons that cause the teeth to lose their vibrant white color. It is important to identify the underlying causes for discolouration in order to develop an effective treatment plan to restore an exceptional smile.

Food and Beverages

The foods we eat and the beverages we drink could potentially cause staining and discolored teeth. Let’s look at some of the more common ones.


Teas contain two ingredients that can alter the color of your teeth, namely tannins and acids. The tannins are a natural plant-based substance which can increase staining on the teeth. The acids in tea cause the protective enamel to weaken and make it less resilient to staining.


Coffee also contains acids which attack the enamel, as well as chromogens. Chromogens are commonly found in dark coloured beverages and foods due to colorized pigments and stick easily to teeth.

Carbonated Beverages

 Sodas can contain corn syrup, sugars, and citric acids, all which cause tooth decay and weakens the teeths ability to resist staining and cavities.

Dark Coloured Fruits and Vegetables

These types of fruits and vegetables could contain chromogens and tannins, as well as acids, which all can lead to stains.

Dentin Discolouration

Dentin is located inside the tooth and sometimes changes in color and eventually starts to show through the exterior of the tooth. Dentin can change colors from a variety of factors and causes including Aging. As we get older, the dentin starts to turn yellow. Accident Impacts to the teeth while they are developing can cause the dentin to discolor.

Certain Medications

Tetracycline is a common one and has been known to affect the color of the dentin.

Excessive Exposure to Fluoride

Too much fluoride during childhood development can cause the dentin to change color.

Rare Dental Conditions

The most common one is very rare and is called dentinogenesis imperfecta.
