An Overview of Teeth Whitening
Your smile is the first thing people notice about you, and you want it to be as sparkling and brilliant as you are. Over time, though, consumption of substances like coffee, tea, and wine, as well as smoking cigarettes, can stain your teeth, making them appear dingy. How do you combat these unpleasant effects of your everyday choices? There are a number of effective options when it comes to teeth whitening.
How It Works
Brushing can clean away some of the staining caused by everyday living. But over time, some of these substances build up within your tooth enamel, causing intrinsic staining. This is the type of discoloration which becomes embedded beneath the surface, and can be difficult to remove.
Teeth whitening treatments utilize either hydrogen peroxide or carbamide peroxide to essentially bleach the enamel, restoring it to a shade closer to the original. These substances bubble into the enamel, breaking up the discolored particles and cleaning them away.
These are the over-the-counter tooth whitening option commonly seen on drugstore shelves. They are effective to a point, but not as effective as professional methods used in cosmetic dentistry.
At-Home Teeth Whitening
Some dentists provide patients with custom-made trays that fit the teeth perfectly. You take these home with a special, concentrated gel, and do your treatments yourself. These are a good tooth whitening option if you have a few weeks to achieve your desired results – say, before a wedding.
These are the methods which offer the fastest results. In-office teeth whitening provides the highest concentration of bleaching ingredient, and the appointments take about an hour. Laser whitening is also sometimes offered in your Lake Oswego dentist office.
