What is the direct answer?
The risks of a Hismile whitening product depend on its ingredients, concentration, contact time, tray fit, and the condition of teeth and gums.
Products may use different peroxide or nonperoxide formulas. Sensitivity and irritation depend on exposure and problems such as exposed dentin, cracks, decay, recession, or gum inflammation.
