Many patients who use our at-home teeth whitening kits enjoy brighter smiles for as long as 4 – 6 months before further treatments are needed. However, your results will depend on a number of factors, including your oral hygiene habits and how often you consume dark drinks, such as coffee or red wine. To maintain your outcomes for as long as possible, our practice recommends brushing your teeth twice daily, flossing once each day, and avoiding foods and drinks that can stain your enamel.
