Common Causes of Yellow Teeth
Poor oral hygiene is one of the causes of yellow teeth, but even the most diligent brushers and flossers can develop the discolored teeth that occur simply with age. Excessive fluoride exposure is also among the causes of yellow teeth, especially in children.4
What Are Other Causes of Yellow Teeth?
Other causes of yellow teeth include:
- Diet: Certain foods that are high in tannins, such as red wine, are potential causes of yellow teeth.
- Smoking: Smoking is one of the top causes of yellow teeth, and stains from smoking can be stubborn. But smokers can improve their yellow teeth by quitting smoking, following a complete oral care routine of twice-daily toothbrushing and daily flossing, and using the right teeth whitening products.1,2,3
- Illness: Certain medical conditions or medications are also causes of yellow teeth. Patients who are undergoing chemotherapy for head or neck cancers may develop yellow or stained teeth. Also, certain types of prescription medications including medications for asthma and high blood pressure are causes of yellow teeth.3
