Why are my teeth yellow?

   Teeth come in many different shapes, sizes and colors. Teeth get there color from the enamel and dentin in each tooth. Enamel and dentin surround the pulp chamber protecting the nerves and blood vessels. Enamel is much lighter in color more of an off white and dentin darker more of a yellow color. Enamel is seen sticking out of the gums and only covers the top portion of the tooth. The root is the bottom part of the tooth and should be covered by the gums. Thus, the roots of teeth do not have any enamel covering them so this part will never be "white" only the top part where the enamel is. Furthermore, enamel is hard and porous like stone. Teeth stains are classified 2 ways intrinsic and extrinsic. First, intrinsic stains are trapped inside the enamel. In early development of the tooth, medication may have been given or a serious illness may have forever changed the color of the teeth. Next, diet choices such as coffee, tea, red wine, dark condiments effect the color of teeth, as well as, iron deposits in home water supplies, inconsistent oral care both at home and professionally. Smoking stains teeth both intrinsically and extrinsically. Furthermore, extrinsic stains though unsightly are easier to treat. These stains lay on the outer surface of the enamel. A few examples are cola's, tea, coffee, smoking, and some mouthwash. Extrinsic stains can become intrinsic if not properly cleaned with a professional cleaning. In Addition, the lack of enamel can make teeth look yellow. The thinning of enamel makes the underlying dentin show through, since this dentin layer is much darker in color the result is yellower teeth. Acid erosion is the greatest cause of thinning enamel. Acids in our diet include pop, energy drinks, coffee, tea, candy, fruit, and vinegar dressings to name a few. Stomach acids from Gerd, reflux, or an eating disorder could also cause thinning enamel. Finally, older adults teeth usually are much more yellow in color. Consequently, many years of acids thinning the enamel, consuming dark colored foods and beverages, and a bad habit or two along the way it isn't any surprise.
