With the proper care, at-home teeth whitening often takes 2 – 3 weeks to achieve the desired shade. To ensure a smooth treatment, our team will provide instructions to follow regarding how often to use your whitening trays and for how long. We recommend that our patients schedule a follow-up exam at our Elk Grove, CA office after about two weeks of whitening treatments so our team can check your progress. Once you have reached your desired appearance, regular touch-ups can help maintain your dazzling new smile.
