The number of treatments necessary will vary based on your need and color preference. On-going whitening treatments may be repeated on a scheduled basis to maintain and rejuvenate your smile. Though most people will notice a big difference after only one treatment, additional treatments could be necessary to achieve the sparkling white teeth you desire.
Whitening durations vary from person to person. Certain food and drinks as well as other factors (i.e. tobacco, medications, age) can all affect the longevity of your results, especially if between visits you continue to use the whitening pen. This easy to use pen can be used anywhere and takes only a couple of minutes to help you keep your teeth looking their whitest.
