Why Are My Teeth Yellow When I Brush Them Everyday?

Just like the myth that chewing gum stays in your stomach for 5-7 years, there’s a common belief that daily brushing and flossing will automatically make your teeth whiter.

But even with good oral hygiene, yellow spots and stains can still appear. So, why are your teeth yellow despite brushing them every day? Well, guess what? It’s not your fault–there are factors beyond your control that determine the color of your teeth. What are those factors? Read this blog to find out.

What is the Actual Color of Healthy Teeth?

The shade of your teeth is influenced by two outer layers: the enamel and the dentin. Enamel, the hard outer layer, is white, leading many to believe their smile should be purely white. However, the inner layer, dentin, is naturally yellow.

If your enamel is thin, the yellow dentin shows through, making your teeth appear yellow. So, we can say that your teeth’s natural color depends on the darkness of your dentin and the thickness of your enamel.

What Causes Yellow Teeth?

There are various reasons why your teeth appear yellow. They are:

  • Poor Oral Hygiene

    Poor oral hygiene, such as infrequent brushing, flossing, and mouthwash use, can lead to yellow teeth.

  • Consuming Certain Foods & Drinks

    Foods and drinks high in tannins, like red wine, citrus, and coffee, can stain teeth by seeping into the enamel and causing discoloration.

  • Smoking or Using Tobacco Products

    Tobacco use stains teeth due to tar and nicotine, leading to yellow or even brown teeth over time.

  • Accidents

    Physical trauma can crack enamel, exposing dentin and making teeth appear yellow.

  • Genetics

    Tooth color can be heavily influenced by genetics, with some people naturally having more yellow or grey shades.

  • Grinding

    Tooth grinding weakens enamel and can result in a yellow appearance.

  • Fluorosis

    Excess fluoride can cause yellow or brown spots on teeth, a condition known as fluorosis, often from overuse of fluoride products.

  • Foods

    Certain foods, like red pasta sauces and dark berries, can stain teeth if not promptly cleaned after eating.

  • Medication

    Some medications and treatments can discolor teeth, especially antibiotics in children, certain mouth rinses and antihistamines in adults.

How to Stop My Teeth from Turning Yellow?

Here’s what you can do to stop your teeth from turning yellow:

  • Over-the-Counter Whitening Products: Temporarily treat yellow teeth with whitening trays, gels and fluoride to lighten their color.
  • Maintain Good Oral Hygiene: Brush at least twice a day, floss daily, and use whitening toothpaste to remove surface stains.
  • Stop Consuming Stain-Causing Foods and Beverages: Avoid staining foods and drinks. If you do consume them, rinse your mouth thoroughly with water.
  • Quit Smoking: Stopping tobacco use helps prevent further yellowing of your teeth.
  • In-Office Teeth Whitening: There are some professional teeth whitening treatments which can give you noticeable results within an hour.
  • Restorative Treatments: Dental veneers and porcelain crowns can address intrinsic stains and transform your smile.
  • Limit the Consumption of Tea and Coffee: Reduce your tea and coffee consumption, or use a straw to minimize staining. Consider switching to herbal teas.
  • Regular Dental Visits: Frequent professional cleanings can help keep both intrinsic and extrinsic stains at bay.
