1.Rinse tray before using, then use tooth wipe to dry teeth.
2.Look in mirror on the back of the power bank, comparing your teeth with the shade guide paper, record which stage you are in.
3.Twist teeth whitening pen, until the gel flows to the brush. Apply teeth whitening gel evenly on your teeth (thickness approximately 1mm). Avoid applying teeth whitening gel directly on your gum or inside of your lips.
4.Connect the SHIRO teeth whitening device with either provided power bank, your iPhone or Android device. Insert mouthpiece into your mouth and bite tightly when the light is on. Take deep breaths before treatment to decrease saliva production (excessive saliva will dilute the gel’s concentration.)
5.Remove mouthpiece after 16 minutes. Rinse your teeth with warm water and compare your teeth with provided shade guide again to see how many shades you have improved.
6.The SHIRO teeth whitening device can be put directly in warm water or washed under running water. After cleaning, put the mouthpiece on a cool and dry place the next use.
