Yellow Teeth from Aging
One of the most common changes to teeth as a result of aging is that they become yellow or stained.
Over time, the outermost layer of tooth enamel can become thinner. This exposes the inner layer, which is called dentin. The dentin is not as white as the outer enamel, and that yellow color can began to show through, giving teeth a yellowish hue. In addition to exposing the dentin, the thinning of the enamel makes it easier for the teeth to become stained from food or drink.
Yellowing of the teeth as you age can also be due in part to genetics, as the amount of enamel on your teeth is determined by heredity. The less enamel you have, the more you will experience the thinning that causes teeth to appear yellow.
For many people, having yellow teeth can affect their level of self confidence and make them feel less attractive. Fortunately, there are many treatments available to treat teeth which have become yellow due to aging.
Over the counter teeth whitening include trays, whitening strips, and pens designed to whiten the teeth. Most of these work by using some amount of peroxide to bleach the teeth. The effects of these treatments vary, as do the prices. Whitening trays are usually the most effective at home treatment, but are also the most expensive.
There are several cosmetic procedures that your dentist can offer as well. Some of these include chair-side bleaching, laser teeth whitening, and dentist supervised gel. Like the at home treatments, you should expect that it may take more than one visit to your dentist to achieve the results you are looking for. The costs vary widely, depending upon the method chosen and the area in which you live. Check with several dentists in your area and compare prices before deciding upon which method of treatment you want to choose.
