You may be looking in the mirror wondering; why are my teeth so yellow? Even if you’re taking care of your oral health, there are many reasons your teeth may not be as white as you would like. Here are some common causes of yellow teeth. 

Poor Oral Hygiene

The leading cause of yellow teeth is poor oral hygiene. Though you may be brushing every day, you may only be brushing for a short time. People with poor oral hygiene brush use mouthwash and floss rarely. This may not be the case for you; just because you are brushing your teeth doesn’t mean you are brushing correctly. 

Foods And Drinks

Some foods have high tannins; one example is red wine; these tannins could stain your teeth, causing permanent discoloration. Some other teeth-staining foods include citrus, coffee, soft drinks, teas, tomato-based sauces, balsamic, curry, soy sauce, balsamic vinegar, fruits, and juices. The ingredients in these foods can cause discoloration because it seeps into your enamel. 

Smoking And Tobacco Products

The tar in cigarettes and cigars can stain your teeth within a short period of time. People who have smoked for many years have visibly brown teeth. Millions of people smoke, causing their teeth to become discolored. Tobacco use could be why your teeth are yellow, even if you are brushing regularly.

However, tobacco can cause other issues that are more major than yellow teeth. 90% of people with cancer in the lips, mouth, tongue, or throat are tobacco smokers. Taking care of your oral and physical health is essential. Using tobacco can cause serious long-term issues, including death. 


Suppose you are undergoing treatment for a significant illness or have just started taking a new medication. In that case, the medication you are taking could be the reason your teeth are discolored. A side effect of some medications and treatments is the discoloration of your teeth; this includes prescriptions for asthma and high blood pressure. 

Children’s teeth are especially susceptible to discoloration from certain drugs. Tetracycline and doxycycline can affect the formation of enamel in children under the age of 8. Mouth rinses can also cause discoloration if they contain chlorhexidine or cetylpyridinium chloride. Other drugs that can cause your teeth to become discolored include antihistamines, antipsychotic drugs, and antihypertensive medications. 

Research the medication you are taking if you can’t seem to get your teeth white, no matter how much you are brushing.
