Laser whitening can be an "all of sudden my teeth are white" kind of move. If you want a more gradual change, and a dramatically less expensive one, in-office whitening could be the right solution for you. Check with a dentist in %cityOrState% that will perform in-office whitening for you! This treatment usually begins in the dentist chair and is completed in your own home. Dentists tend to use a nightguard system in which they will custom fit a tray for your mouth and fill the tray with a peroxide mixture. Usually the nightguard is worn overnight but can be worn over a period of a few hours. Your dentist will let you know what is best and more importantly, whether this in-office treatment is right for you. The cost? Anywhere from $250 to $600.
