Electric Brushing
There are many manufacturers of these brushes, so it is really a matter of personal choice and subjective assessment which seems best. The importance is that they may reach places that hand brushing does not, providing that sufficient time is spent cleaning each separate area of the mouth. Some electric toothbrushes have timers as an aid to assist in this.
Again, the importance is to watch what patients do, and correct any errors, remembering to suggest changing hands as described above.
