Description

A kind of electric toothbrush

Technical field:

This utility model relates to the articles for daily use technical field, refers in particular to a kind of electric toothbrush.

Background technology:

Tooth can not only laboratory rodent chow, help pronunciation, and U.S.A of face is had a significant impact.Because the support of tooth and alveolar bone, dental arch form and occluding relation normal just can make people's face and lip buccal seem plentiful.And when people's speech and smile, neat and pure white tooth more can manifest the healthy and beautiful of people.On the contrary, if dental arch grow undesired or can not get the protection of reasonably healthy, the tooth arrangement disorder, uneven, red swelling of gingiva is hemorrhage, it is inharmonious that face will seem.If absence of tooth is too many, the lip buccal loses support and caves in, and people's face is presented a weathered appearance, become thin.Especially dental haemorrhage, and cause and produce abnormal flavour in the oral cavity, be to cause the very big obstacle of linking up between people and the people more.So, people often tooth as weighing one of vigorous and graceful important symbol.
