Whiteness depends on the degree of discoloration as well as many other factors as well how your teeth respond to whitening. In general, your teeth can be whitened up to eight shades, but it takes a change of just two to three shades to make a noticeable difference.
Your own long-term results will be influenced on your eating and drinking habits (dark berries, coffee, tea, red wine, etc.). If you find it hard to completely eliminate these and other stain-causing choices from your diet, touch-up treatments at regular intervals will definitely be necessary. We’ll help you decide which treatment is the best one for your smile, and Opalescence also offers a whitening toothpaste to help keep your teeth their whitest and brightest longer.
