The supragingival air/powder jet is powerful. It can cause injury to the gums or an emphysema
caused by the introduction of air into the soft tissue spaces. It is strongly recommended that the operator
never direct the nozzle directly at the gum tissue or into the gingival sulcus.
During treatment, make small circular motions.
Finally after the treatment polish all dental surfaces by setting the water flow rate to the maximum.
