If you're looking for a bright smile, you'll want to consider teeth whitening. Your dentist can do all the heavy lifting, so to speak, but you may wonder what exactly goes into this popular procedure. Here, we'll outline the process and shed light on modern teeth whitening.In order to get rid of stains, dentists use a carbamide or hydrogen peroxide treatment. Depending on your specific situation, your dentist may do the entire process in the office or may elect to have you do some of the process at home.
The first step of an appointment will be to thoroughly clean and inspect the mouth. If any cavities are discovered, they'll be filled immediately. If the gums show any signs of being unhealthy your dentist will discuss those issues with you prior to starting the teeth whitening process.
Most dentists then use a special pumice to further clean each individual tooth. Following that, a protective barrier will be placed on the gums. A customized paste, containing between 15 to 35 percent hydrogen peroxide, will be applied to the teeth and will stay there for several minutes. After rinsing it off, the same paste will be applied again. The dentist may complete this cycle several times during one 30- to 45-minute treatment. Some dentists choose to pulse high-powered light on the mouth area as well. In this small amount of time, your teeth could become four to six shades whiter.
In the cases in which the dentist recommends at-home treatment, he or she will first take molds of the patient's mouth. Custom mouth trays are made, and a gel containing approximately 10 to 20 percent carbamide peroxide gel is prescribed. The patient applies the gel at home and wears the trays for a few hours or overnight to keep it in place. This process can take as long as six weeks.
