Teeth Whitening is a common procedure for those patients wishing to lighten their teeth without the need to prepare (reshape) teeth for dental restorations. There are many factors that affect the color of your teeth. Coffee, tea, tobacco, red wine and age can all darken teeth. Using customized molds, the whitening solution fills in the areas around and between each tooth and allows one to lighten teeth at home in a one to two week period of time. For those patients desiring more immediate lightening, in-office procedures can be performed to provide a same day tooth whitening.
