The product has been developed specifically to provide precise application to teeth, so you can avoid applying to the gums. The formula is also specially designed to minimize the risk of sensitivity, with a low peroxide concentration and slow-release technology. To minimize irritation, avoid contact with gums and soft tissue.
Some people may experience tooth sensitivity or gum discomfort when using whitening products. This discomfort is temporary and not harmful. If significant tooth sensitivity or gum discomfort develops and persists after use, consult your dentist or physician before continuing use.
