Common Causes of Teeth Discoloration

Tooth discoloration can stem from many root causes, including preventable and non-preventable sources. You can review the below causes to find out what might be causing your tooth discoloration, how to prevent it, and ways to fix it.


One common reason for tooth discoloration is as simple as the food you eat and the beverages you drink. Coffee, tea and wine are well-known for causing tooth yellowing or discoloration. Many people choose to use a straw to avoid beverage contact with the tooth surface. Some fruits and vegetables, including apples and potatoes, have also been found to cause discoloration. Smokers also often have tooth discoloration from the use of tobacco, which stains the surface of your teeth.


Dental hygiene is critical, and if your brushing, flossing and rinsing regimen is not sufficient, poor dental hygiene may ensue. Make sure to brush twice daily and floss daily, as well as use an antiseptic mouthwash to ensure proper dental hygiene and avoid unnecessary tooth discoloration.


There are medical reasons why some people may find their teeth become discolored. There are diseases that affect the teeth (either the enamel surface or the dentin material that underlies the enamel). Radiation, chemotherapy, and some infections have also been found to lead to tooth discoloration. Some medications also lead to yellowed teeth, including antibiotics that may cause discoloration in young children as their teeth develop. Some antihistamines, antipsychotic drugs, and high blood pressure medications also create tooth discoloration.


Genetics and aging also play a role in tooth discoloration. Enamel plays a big role in tooth appearance, so people who are genetically predisposed to having brighter or stronger enamel may be less likely to see tooth discoloration. As people age, natural wear and tear causes some erosion of the enamel, which leads to a yellowed or discolored appearance. Some environmental factors also play a role, like the use of excessive fluoride in water or in dental products like toothpaste or mouthwash.


If you have concerns about your tooth discoloration, talk to your dentist about the causes for your dental appearance and potential ways to prevent further discoloration. There are plenty of options available for treatment, so book an appointment with your dentist to discover what treatment options you may be able to pursue.
