Powerbrushes: Electric and Sonic

There are two main types of power brushes:

• Electric brushes: with 3000 to 7500 rotating brushes a minute electric toothbrushes are powered to replicate the motion of your hand doing the muscle work for you. The bristes on the electric toothbrush rotate or move back and forth, this is to help accomplish the removal of plaque and reduce gingivitis.
• Sonic toothbrushes: Offering 30, 000 to 40, 000 stroke per minute sonic toothbrushes  rotate in a back and forth vibrating motion.
