There are several different types of professional teeth whitening: in-office and out-of-office. Both types offer their own benefits in terms of how long they take and how white your teeth will be after.
In-office treatments offer quick results that will have you smiling! During this procedure, a safe bleaching solution will be applied to your teeth and activated with a high intensity light. After about an hour, your teeth will have the glamourous white glow you’ve been seeking, and correct your tooth discolouration.
Out-of-office methods take longer but offer the convenience and comfort of being at home. A custom whitening tray using a mould of your teeth will be created. You will then be given a whitening gel that fills the tray. You will wear the tray 3-4 hours a day for one to two weeks. At the end of this time, you will notice considerable whitening.
Following either treatment, you could experience tooth and gum sensitivity for a few days. If the sensitivity persists, contact your dentist.
