What It’s Good For

Thorough Cleaning:
Typically, the electric toothbrush head is smaller than manual toothbrush, making it can reach hard-to-clean areas and with high-frequency vibration make it can remove plaque although there is no space to move the brush.

Enamel & Gums:
Brushing too hard may lead gum recession and enamel thinner, one of the causes of sensitive teeth. Most electric toothbrushes featured with pressure sensor and timer which will beep or stop working when detected excessive pressure and brushing too long.

Brushing wrong way besides the plaque was not removed cleanly, it may also damage the enamel. That are common problems in children and seniors who do not have skills to brush their teeth or cannot grip manual toothbrush with flair. Using the electric toothbrush can be used to solve this problem because it’s easy to use and clean effectively.
