Does teeth whitening affect your enamel?

Types of Teeth Whitening:

  1. At Home – The dentist will take an impression of your teeth to make tailor made trays for you like a mouth-guard, and ask you to come back in a weeks time. During your second visit Dr Dhody will tell you how to use it with a bleaching gel. Then, using your trays at home, you regularly apply the gel for a specified period of time over 2 to 4 weeks depending on how white you want your teeth to be. Some whitening gels can be left on for up to 8 hours at a time.
  2. In Surgery– Zoom or laser whitening, also known as power whitening, is another type of teeth whitening system that a dentist can provide. A bleaching product is painted onto your teeth by the dentist and then a light or laser is shone on them to activate the whitening. Laser whitening takes about an hour and more.
