Description

Tooth cleaner

Technical Field

The invention relates to the technical field of teeth, in particular to a tooth cleaner.

Background

The health of the mouth, i.e. the teeth, is one of the criteria for human health. The healthy teeth are beneficial to chewing, stimulate salivation and are beneficial to digestion and absorption of food. In the childhood stage, teeth assist lip and tongue development, and teeth are also associated with swallowing and facial expression. Effective and correct brushing is the primary measure for maintaining dental health and accompanies a person's lifetime. Especially, in the stage from children to children, when the children are 6-13 years old, the deciduous teeth are fallen off, and the permanent teeth are alternately erupted, the teeth can not be cleaned correctly and effectively. Uncleaned teeth and residual food are beneficial to the growth and proliferation of bacteria, oral odor, dental caries, gingivitis, pulpal neuritis and the like.

The existing tooth cleaning method is to clean food residues around and among teeth by using a hand-held toothbrush to brush teeth, but the tooth brushing method is difficult to effectively clean the teeth, and the teeth are easily damaged if the toothbrush is used by mistake (horizontal brushing).

Disclosure of Invention

The invention provides a tooth cleaner with good tooth cleaning effect, aiming at overcoming the defect of poor tooth cleaning effect in the prior art.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a tooth cleaner, includes facing base plate, elastic layer and the facing body, the equal symmetric distribution of elastic layer and the facing body is in the upper and lower both sides of facing base plate, the elastic layer is fixed between the facing base plate and the facing body, be equipped with the tooth bed groove on the facing body, the tooth bed groove is arranged in on the side that the facing body carried on the back mutually with the elastic layer, the inside evenly distributed in tooth bed groove has a plurality of tooth's socket, equal sliding connection has the clean piece of flank of tooth on the lateral wall of the relative both sides of tooth's socket, be fixed with the connecting rod on the clean piece of flank of tooth, the connecting rod link up the bottom surface in tooth bed groove in proper order and the elastic layer just articulate mutually with the facing base plate.
