I Brush My Teeth, Why Are They Still Yellow?

I brush my teeth at least twice a day, but my teeth are still yellow, why? Good question. As we age, the enamel on teeth wears, and the yellowish dentin underneath starts to show through. Most causes of tooth discoloration fall into two main categories: extrinsic and intrinsic stains. Yellowing can also be caused by a wide array of health factors, from medication use to inadequate brushing.



Extrinsic stains affect the surface of the enamel, which is the hard, outermost layer of teeth. The number one cause of teeth yellowing is lifestyle; coffee, smoking, drinking, teas, etc. Although tooth enamel can be easily stained, these stains can typically be removed or corrected. Intrinsic stains occur within the inner structure of the tooth, called the dentin, making these stains more difficult to remove. Besides stains, some other causes of discolored teeth include genetics, age, illness and injuries. Typically over-the-counter whitening strips will not have a lasting effect on your teeth. As with any condition, it's best to consult a board certified specialist on the best method to remove the yellowing of teeth.
