Whitening Frequency: How often you need whitening depends on your maintenance of it afterwards. It is not uncommon to repeat the procedure within 6~12 months. With the aid of touch-up pens, whitening strips, whitening toothpastes, avoidance of food and drinks that stain, and even brushing and rinsing frequently after such consumption could prolong the effects of treatment, keeping your teeth white longer.
