The Color Matters
Dentin, one of the inner materials of teeth, is naturally yellow, and as the enamel on the surface of teeth wears away, it’s normal for teeth to start showing this hue.
On the other hand, teeth may also become gray or brown because of the materials used in previous dental procedures, the consumption of staining items like tea or tobacco, or even experiencing disease within the mouth.
Fortunately, most patients will respond well to tooth whitening. Those with yellow teeth are more likely to see benefits, while those with gray or brown teeth may not see as much improvement from standard whitening procedures.
