There are few people today who don’t want a dazzling smile. And that means one thing: whiter, brighter teeth.
Teeth whitening has become a big business, with more people than ever before spending lots of money to fulfill their desire for a great smile. With the host of treatment options available today, that smile may only be one teeth whitening procedure away.
There are not many of us who maintain white, bright teeth as we age. For most of us, discoloration is an inevitable consequence of getting older. But it doesn’t have to stay that way, especially since there are all kinds of effective teeth whitening options available today.
The surface of our teeth typically become stained because of what we eat and drink over the years. Things like coffee, red wine, soda, and tea are all major contributors to the discoloration that we see. Smoking, of course, is another major factor.
Discoloration is not confined to just the surface of your teeth. When the enamel on the surface of a tooth develops cracks, the dentin below the surface can become yellow. Also, if certain antibiotics are taken during the years that your teeth are forming, discoloration can occur as well.
One popular method of teeth whitening today is tray bleaching. We will look at this method and how it works in the rest of this article.
In tray bleaching, a tray is custom fitted to your mouth’s unique shape and then a whitening compound is put in the tray. The tray is then placed inside your mouth over your teeth, which applies the whitening chemical to your teeth.
Typically, peroxides such as carbamide peroxide or hydrogen peroxide are used as bleaching agents. As they decompose inside the patient’s mouth, oxygen is released which then penetrates the teeth’s surface, providing whitening to the dentin below as well as to the surface.
About four weeks is needed to complete the tray bleaching procedure. The first thing your dentist will do is make an impression of the inside of your mouth and create a tray that is custom fitted to it. Once the tray is ready and treatment begins, you will use it at home for 3-4 weeks, applying the whitening agent for about half an hour each day.
Teeth bleaching is one popular teeth whitening option. Your dentist will be able to help you decide if it is the right choice for you.
