5 Best Electric Toothbrushes in 2017, 2018
An electric toothbrush is a toothbrush that creates rapid, automatic bristle motions, either to-and-fro oscillation (about 45 degrees) or rotation-oscillation (in which the brush head alternates clockwise and anticlockwise rotation), in order to clean teeth.
Electric Toothbrushes are now more equipped to remove plaque and gingivitis. It also helps to minimize the risk of tooth decay and gum problems by maintaining tooth hygiene.

Types of Electric Toothbrushes
1. Based on the type of action that they produce (vibration or rotation-oscillation)
- Vibrating toothbrush : A brushing technique similar to that used with a manual toothbrush.
- Rotating-oscillating toothbrush : Simply move the brush slowly from tooth to tooth.
2. Based on the speed of their movements
- Standard power toothbrushes
- Sonic toothbrushes : If the motion of the toothbrush is enough rapid to produce a buzz in the range of audible frequency of human (20-20,000 Hz). Motions at sonic speeds or below are produced by a motor.
- Ultrasonic toothbrushes : If the motion of the toothbrush is faster than to produce a buzz in the range of audible frequency of human (20 Hz to 20,000 Hz). Ultrasonic motions are produced by a piezoelectric crystal.
Now a days, modern electric toothbrushes are common which are usually powered by a rechargeable battery charged through inductive charging when the brush sits in the charging base between uses.
