To date, the most recognized in-office teeth whitening system is Phillips Zoom. This treatment works by activating a peroxide-based whitening gel with LED light. The gel remains under light activation for about 15 minutes before it is removed. After observing the level of white that has been achieved, the dentist may repeat the process again. This can be done up to three times to lift the shade of teeth up to eight shades. The benefit of this single treatment is that it achieves dramatic results very quickly.
Opalescence Boost is also performed in the office in a single visit. Similar to other in-office teeth whitening treatments, it involves an application of a powerful whitening agent to the teeth. In this case, the whitening gel remains for about 20 minutes, after which it is suctioned and cleaned away. Depending on the level of whitening that has occurred within that twenty minutes, the process may be repeated. You can have three 20-minute sessions in one visit. This can achieve up to eight shades of brightening. The difference is that the whitening gel in Opalescence Boost is not activated by light.
There are a few advantages of Opalescence Boost not using light to activate the whitening gel. Although this system can achieve similar results to Zoom, it can do so without the risk of dehydrating tooth enamel. According to many patient reports, Opalescence Boost also seems to achieve outstanding results without causing the degree of post-treatment sensitivity that Zoom does.
