    Why Are My Teeth Yellow When I Brush Them Everyday?

    Maintaining a bright, white smile is a common goal for many people but brushing teeth everyday didn’t mean that your teeth will turn white. This is a common concern and can be attributed to several factors.

    It’s important to understand that while brushing is crucial for oral health, it’s not the only factor that affects the color of your teeth.

    #1.Natural Tooth Color

    Genetics and Dentin:

    The natural color of your teeth is influenced by genetics and the composition of your teeth. The outer layer of your teeth, called enamel 1, is typically white, but the layer beneath it, known as dentin, is naturally yellowish or brown. If your enamel is thin or your dentin is darker, your teeth may appear yellow despite regular brushing.

    #2. External Staining Agents

    Food and Beverages:

    Certain foods and drinks are notorious for staining teeth. Beverages like coffee, tea, red wine, and colas contain chromogens, which are deeply pigmented molecules that adhere to the enamel, causing discoloration over time.

    Tobacco Use:

    Smoking or using tobacco products is a significant cause of yellow teeth. Nicotine and tar from tobacco seep into the enamel through tiny pores, leading to persistent stains that are difficult to remove with regular brushing.

    Poor Oral Hygiene:

    While brushing is essential, it is not the only aspect of oral hygiene. Failing to floss and use mouthwash can lead to plaque and tartar build-up, which can contribute to yellowing teeth.

    #3. Internal Factors

    Medications and Health Conditions

    Certain medications, such as tetracycline and doxycycline, can cause tooth discoloration, especially if taken during childhood when teeth are still developing. Health conditions like enamel hypoplasia and dental fluorosis can also lead to yellow or brownish stains on teeth. 2


    As we age, the enamel on our teeth naturally wears down, revealing the yellow dentin beneath. This process is exacerbated by years of wear and tear, making teeth appear more yellow over time

    Trauma and Bruxism:

    Trauma to the teeth, such as a severe impact or injury, can cause discoloration. Additionally, teeth grinding (bruxism) can wear down the enamel, exposing the yellow dentin and leading to yellow teeth.

    Types of Stains on Teeth:

    Extrinsic vs Intrinsic Stains

    Tooth stains can be classified as extrinsic or intrinsic. Extrinsic stains affect the surface of the teeth and can often be removed with proper brushing or professional cleaning. Intrinsic stains, on the other hand, affect the internal structure of the teeth and are much harder to eliminate. 3

    Solutions & Preventive For Yellow Teeth

    Professional Whitening Treatments:

    For those struggling with yellow teeth despite regular brushing, professional in-office teeth whitening is one of the most effective solutions. These treatments use high-concentration bleaching agents to remove deep stains and can provide dramatic results.

    At-Home Whitening Kits and Over-the-Counter Products:

    At-home whitening kits and over-the-counter products, such as whitening toothpaste and strips, can also help reduce surface stains. However, they are generally less effective than professional treatments.

    Lifestyle Changes:

    Making lifestyle changes, such as reducing the consumption of staining foods and beverages, quitting smoking, and maintaining good oral hygiene, can help prevent further staining and maintain whiter teeth.

    Cosmetic Dentistry:

    For severe discoloration, cosmetic dentistry options like dental veneers and bonding can cover stained teeth with a thin layer of tooth-colored material, providing a long-lasting solution.


    While brushing your teeth every day is crucial for maintaining oral hygiene, it may not be enough to prevent yellowing. Factors such as genetics, diet, tobacco use, aging and certain medications can all contribute to tooth discoloration. Understanding these factors and seeking appropriate treatments can help you achieve and maintain a bright, white smile. If you’re concerned about the color of your teeth, consult with a dental professional to determine the best course of action for your specific situation.
