You’ll see results right away, usually within three days of starting the whitening process. The complete process normally takes between one and two weeks, but treatment times will vary depending on the source, type, and depth of the discoloration.
Your dentist will first check your teeth and gums to be sure that you begin the treatment in good dental health. Then your dentist will take an impression of your teeth in order to provide you with a custom-fit plastic tray designed to hold the bleaching gel next to your teeth. Following the bleaching program your dentist suggests, you’ll notice the results quickly, as the gentle oxygenating action of the gel begins to whiten your teeth. Your dentist may choose to begin with a short in-office bleaching session.
There is little, if any. Some patients might feel an increased sensitivity to cold, heat, or pressure during the whitening process, but this sensitivity ends a day or two after the treatment is completed. Any note of persistent discomfort should be reported to your dentist.
