The Boost tooth whitening system is a powerfully formulated bleaching gel that is applied directly to the teeth. Once the gel is in place, you relax and watch Netflix for 20 minutes. This procedure is repeated as needed. The whole process takes about an hour. After the final whitening treatment, the teeth are rinsed thoroughly. And that’s it. In less than an hour, an average of 8 shades of whitening will have been achieved. The teeth whitening treatment is simple, non-invasive and comfortable. No need for anesthesia and side effects are minimal.
