The frequency of your teeth whitening treatments at our office will depend on a number of things, including your desired brightness and your consumption of food and drinks that stain your enamel. To enjoy your results for as long as possible, we recommend avoiding items like coffee, red wine, and tea. Even following those guidelines, your teeth will eventually start to dull over time. Generally, we recommend follow-up treatments every six months to two years, according to each patient's needs and habits.
