Zoom dental whitening gel for in-office treatment may have a concentration of bleaching gel that's as high as 35%. This is the key to getting instant white teeth in just one office visit. The bleaching process is further activated by a ultraviolet light. Our trained professional staff members will ensure you wear eye protection and isolate all of the gum tissue and lips. Once your teeth are white, there is very little maintenance after. Please ask us about our Zoom whitening special!!
