Electric toothbrushes or power brush:
A power brush has an oscillating rotating or vibrating head, which provides a large amount of cleaning action with very little movement needed from the user, still need to position the brush correctly.
Tests have shown that they are more effective at removing plaque. Those with heads that rotate in both directions are the most effective. They are particularly useful for people with limited movement of the arm or hand, such as disabled or elderly people, who often find that using a normal toothbrush does not allow them to clean thoroughly. Power brushes can also be better for children as they may be more likely to brush regularly because of the novelty of using a power brush.
