Regulations regarding teeth whitening are different from state to state. Each state continues to change its regulations as the years go by so we must continue to monitor the state boards. In California, at this time, a dental assistant can administer the teeth whitening material as long as there is a dentist supervising in the office. Zoom II and BriteSmile are easily and safely administered by a dental assistant. After working with theses systems. 
 
In my office we change the whitening gel depending on the patient’s needs and sensitivity level. The tray design can be changed to accommodate different levels of gum disease and recession. We also change the instructions and the frequency of whitening depending on the patient. The process needs to be customized for the best results.
