Tooth whitening is the process by which the yellowish layer of teeth is removed to give pearly white teeth. The process lightens the natural color of the yellowish teeth without removing any of the tooth surfaces, thus giving a brighter tooth color. Of late, there are many varieties of products and procedures available that help improve the smile by whitening the teeth. Obviously, better looking teeth and a better smile improve the overall look.

Of the many types of tooth-whitening procedures available, the at-home bleaching kit is the most popular choice. Mouth trays, which are aids that are used in tooth whitening, are usually made in just one office visit. Some of these trays are worn for an hour, and others have to be through the night. Dentists charge anywhere between $100 and $600 for tooth-whitening services, and the prices of tooth-whitening kits vary from company to company.

Bonding of teeth is done by using a composite resin that is molded onto the teeth in order to change their color and to reshape them. Also, porcelain veneers, which are shell-like facings, can be bonded onto stained teeth. These are used to reshape and lengthen teeth, as well as to whiten them. Toothpastes that offer to whiten teeth are also effective in keeping the teeth cleaner and, therefore, looking whiter. The latest high-tech option in tooth whitening is laser tooth whitening. Needless to say, the tooth-whitening toothpaste is the cheapest option when compared to all these other treatments.

It is advisable to first confirm with the dentist the best method. People with joint problems and high sensitivity to hot and cold foods or drinks as well as those with crack lines in their teeth are better advised against tooth whitening. Gum infections should be treated before the procedure is carried out. Pregnant or breastfeeding women should be excluded from bleaching procedures since there is no adequate knowledge regarding the possible ill effects on pregnancy.
