You cannot be taught to play tennis or golf by reading about them. You must be instructed, and you must practice. Similarly, you should learn the right way of brushing under the strict supervision of your dentist. 
 
The tooth has five surfaces - front, back, the two sides and the chewing surface. Brush the top and bottom teeth separately. Most dentists agree that the bristle tips should be applied at 45 degrees to the gum area just above where the teeth emerge and should concentrate on the gum margins (where most people miss). The bristles are moved back and forth with a gentle circular scrubbing motion and short strokes. Do not forget the teeth right at the back of the mouth and also the inside surface of  the teeth. Finally brush all the biting surfaces. It often takes three or four visits to teach someone to brush effectively!

Tips on Brushing

• Do not put too much toothpaste on the brush, it will foam up and make you want to spit and rinse too soon. Studies show that once people get to the spit and rinse stage they stop brushing even though some teeth have not been brushed.

• Do not wet your brush before applying the paste or before starting to brush. It alters the action of the bristles and prevents them removing plaque effectively.
