How you hold a pen with fingers? Hold the electric brush in the same way using finger grip. Use of fist grip is wrong, as it leads to forceful brushing and brushing accuracy is not maintained. Different models have different shapes of handle. So you should study the model's manual to know more about the required grip.
The head of the tooth brush should be placed on the line where teeth and gums meet. Then the tooth brush should be moved gently forward and backward around this line. Thus bacterial plaque and food debris will be cleaned automatically.
While cleaning around this boundary line, also clean every tooth's surface. Gaps between the teeth and the back of the teeth are also to be cleaned simultaneously. It will be better if you clean each tooth turn wise. In this way no tooth will remain unclean, and you will develop a good habit. Sonycare 'Quadpacer' technology has the benefit of dividing up mouth in four parts; it helps to clean all areas of mouth in a better way.
