Why Do My Teeth Look Yellow Even Though I Brush Every Day?

When you brush your teeth twice a day and diligently floss every night before bed, and your teeth are still yellow, it can make you wonder whether it’s worth the time and effort. The truth is that yellow teeth can make you cover your mouth when you smile and avoid being in photos.

So, what causes yellow teeth, even in people with good dental hygiene habits?

Why Are My Teeth Yellow?

Daily brushing can’t change the color of your teeth; it can only clean the surface.

Here are some common causes for yellow teeth:

  • Thin enamel — Your tooth enamel is the hard, protective layer on the outside of your teeth. So, if your enamel gets thin from brushing too hard or other reasons, the yellow dentin layer underneath begins to show through.
  • Genetics — Some people are born with thinner enamel than others, so your genetics can make it possible for the yellow dentin layer to show.
  • Aging — As you get older, your tooth enamel naturally begins to wear down. Wear and tear and acidic food and drinks can add to this.
  • Food and drink — If you drink coffee, tea, red wine, soda, or consume dark sauces, it can stain your teeth, and brushing can’t always remove these stains.
  • Tartar buildup — When plaque is on your teeth for an extended period, it hardens and turns to tartar, a yellowish substance that only a professional cleaning can remove.
