Most patients will start to see results after 3 to 4 weeks.
Professional teeth whitening appointments generally take between 30 and 60 minutes.
At your initial consultation, your dentist will likely start with an exam that may include x-rays to help decide which treatment is best for your case. They may also take before and after photos to measure the success of your treatment.
Most appointments at your dentist's office will begin with a short teeth cleaning to clear away plaque, tartar, and other debris and “prep” your teeth for treatment. Your dentist may then use a cheek retractor, which pulls the cheeks away from the teeth. From there, they will use rubber dams or resin to protect the gums. They will then apply a gel to the teeth, leaving it on for 15 to 30 minutes before cleaning off and reapplying. Your dentist may reapply multiple times during the treatment.
