In just one appointment, your dentist can remove stains that have taken years to develop. You’ll be in the office for less than one hour. To perform the procedure, your dentist will apply a whitening gel, which is activated with a UV lamp. Once your appointment is complete, your teeth will be several shades lighter than they were before you entered the dentist’s chair. In the teeth whitening industry, many practices use the latest technology to give you the best results. New technology can also decrease the amount of tooth sensitivity that you experience during the procedure. Less sensitivity translates to greater patient comfort.
