Teeth whitening involve whitening teeth to make them lighter. Teeth whitening cannot make your teeth bright white, but you can lighten the existing color with various shades. Bleaching is one of the most popular cosmetic dental procedures because it can greatly improve the appearance of your teeth. Most dentists perform teeth whitening.
If you have teeth whitening you will need to make several visits to dental surgery for a couple of months. Bleaching is not a one-time procedure. It will have to be repeated from time to time if you want to keep the color brighter. There are two main types of whitening procedures. Vital whitening is done on teeth that have live nerves. Non-vital whitening is done on a tooth that has had root canal treatment and no longer has a live nerve.
Another type of teeth whitening system is called laser whitening, which is also known as power whitening. This is where a whitening product is painted on the teeth and then a light or laser is turned on to activate the whitening. Laser whitening takes about an hour.
