Electric toothbrushes offer several advantages over manual brushes. Because they're driven by a motor, many more brush strokes can be achieved in a session, allowing more bacterial plaque to be removed compared to a regular brush, which may help reduce the incidence of tooth decay and gingivitis.
Some models produce sound waves that kill bacteria by bursting their cell walls, improving the effectiveness of the brush - even where the bristles may miss.
Some electric brushes tell you when it's time to switch areas of the mouth by beeping, or momentarily interrupting the brush's motion.
Electric brushes are great for people with arthritis, whose limited dexterity may prevent effective brushing with a manual toothbrush.
And finally, electric brushes often come with a timing feature that tells you when the brushing session is over.
Be sure to talk to your dental professional about whether an electric toothbrush could improve your oral hygiene. And keep in mind that no matter how effective your brushing is, you will still need to floss daily to prevent periodontal disease and the type of decay that arises between the teeth.
