Tooth whitening is an effective way of lightening the natural color your teeth have without damaging the tooth’s surface. This process is unable to make a complete color change, but it can lighten the existing shade of your teeth.
Why you need tooth whitening
There are many reasons why you need to get your teeth whitened. Everybody has a different shade color of their teeth the same as everybody has a different skin or hair color. Only a few people have extremely white teeth. Also, as you get older your teeth will lose their color and start to become yellow, gray or brown. Your teeth can get stained from want you drink (tea, coffee, red wine) and eat (strawberries, grapes, cranberries). If you smoke or chew tobacco, your teeth will also lose their color. Tartar also affects the color of your teeth.
What the whitening process involves
The whitening process is the most used method for tooth whitening. Ask your dentist if you are suited for the treatment and supervise you if you are in need of tooth bleaching. First the dentist will put a gel or rubber shield on your gums to protect them. Then they will apply the whitening product to your teeth with a specially made tray that looks like a mouthguard. As active ingredients the products usually have carbamide peroxide or hydrogen peroxide. The active ingredient is broken down, and oxygen gets into the enamel to make the tooth’s color lighter.
This treatment could last for up the three-four weeks. In the first few visits, the dentist will make a mouthguard that will fit your teeth. Then, once the treatment has started, you can continue to do the treatment at home by yourself (30-60 minutes at a time for three-four weeks).
Now you can also choose to do laser or power whitening. These are two new procedures that have the same effects as the tooth bleaching process. Laser whitening can make your teeth 5-6 shades whiter.
Are there any side effects?
There are some people that will have a slight tooth sensitivity to cold during and after the treatment. Others develop a small discomfort in the gums, white patches on the gum line and a sore throat. But these symptoms are usual and are only temporary. They disappear within a couple of days after the treatment has ended. If any of the symptoms continue after a week since you finished the treatment, you need to visit a dentist.
