You simply apply the bristles to the gumline, press lightly until the motor slows slightly, and slowly move from tooth to tooth around your mouth. The sparkling clean feeling which results rivals the just cleaned feeling of coming from your dentist. In fact, the action is so thorough that with a little training you can clean your teeth with this brush significantly better than the majority of dentists can clean their own teeth with a normal hand held brush. I require that severe, advanced periodontal patients use this brush if they still have plaque remaining after they hand brush. If you have not mastered brushing by hand in 50 or so years, I have no any idea how to teach this difficult task.
Automation is the solution.
All electric brushes are not equal. The Interplak for example is one of the best in my opinion for cleaning teeth but has the worst repair record. Fortunately it has a two year warranty. Every brush my patients have returned so far has been promptly replaced at no charge. Some of the breakage is due to lack of proper care.
