Description

The cambered surface Folding toothbrush

Technical field

The utility model relates to a kind of toothbrush, exactly is a kind of cambered surface Folding toothbrush.

Background technology

Existing toothbrush bristle of a great variety is different, toothbrush can be divided into plane, inner concave type and undaform or sawtooth pattern according to the brush finish shape of bristle, and still, the bristle shape of existing toothbrush is not suitable for the method for brushing teeth of science.The method for brushing teeth of science is that bristle is brushed up and down along the direction of dental growth, and the right and left of existing its brush finish of bristle is along the middle part that all is greater than or equal to brush finish, when toothbrush when brush is moving up and down in the oral cavity, if the brush finish middle part contacts with tooth, the right and left of brush finish is along touching gum surely, be prone to brush and hinder the situation of gum, cause bleeding gums, influence oral health.Therefore, current toothbrushes can not satisfy people's instructions for use.

Summary of the invention
