Why does someone even have yellow teeth? Without much thinking, I can think of several reasons why white teeth are not in the cards for everyone. Let us start with food; stains from blueberries, blackberries, beets, gelatin, food coloring, and so forth that cause tooth stain. Then we have beverages like coffee, tea, carbonated beverages, juices and more that prevent our teeth from being their whitest. Next let us consider medicines, it is a well knows fact that tetracycline can cause yellow teeth, but not everyone does not know that the topical applications of fluoride can cause tooth stain. When topical fluoride is applied unevenly this can result in white patches on the tooth surface, this can trap foods and cause a stain. White patches on the tooth surface can also be caused by ingesting too much fluoride. Damaging the enamel surface can be the culprit for yellow teeth. Sometimes a person brushes so often with such harsh teeth whiteners, that we can actually damage the protective surface of the tooth. The list for causes of less than white teeth and yellow teeth is indeed a long list. Some people are just plain born with yellow teeth.
