Whitening is a mild bleaching process that restores stained or discolored teeth to a healthy, natural color, and is very safe under the supervision of a dental professional.
The results from Whitening can last for as long as a year.
Some patients may experience heightened tooth sensitivity or mild tooth or gum sensitivity during treatment, but these symptoms are only temporary and disappear within a few days after the treatment is finished.
With protective glass and mouth opener for the patient, blow to dry the tooth surface then apply gum protective agent (Vitamin E) onto the border of gum and tooth；
Gently apply Whitening Gel onto the surfaces of 20 teeth at upper and lower portions respectively, then initiate the cold light to activate the gel ；
After 15~20 min, remove the used gel；
At last rinse the tooth surface carefully and allow the patient to thoroughly wash mouth.
