Description

Between visual tooth, brush

Technical field

This utility model relates to a kind of oral cavity cleaning instrument, between the tooth especially for cleaning teeth gap, brushes.

Background technology

Due to the reason such as age growth, pathologic, be easy to cause gingival atrophy, interval of tooth to expand, very easily cause the residual of food, if can not clean in time, can produce halitosis on the one hand, easily cause on the other hand the generation of various odontopathy, oral disease, particularly periodontitis.

For this situation, develop in the market between various teeth and brushed, or claimed interdental brush, select for user.Although have now the product of various structures, different size on market, existing product ubiquity is difficult for observing the shortcoming of teeth space.Especially in the time of the teeth space cleaning between the teeth space between third molar and second molar or teeth space or first molar and the second premolars between second molar and first molar, because required cleaning teeth space position is in depths, oral cavity, therefore clean position light is very dark, in the time there is no exterior lighting, user can only operate with feeling.The working portion of brushing between the tooth of prior art adopts wire cable to adhere to the hair brush structure of macromolecular material fiber conventionally, and therefore, when feeling to operate, tinsel is very easy to stab gingiva tissue.

For preventing that tinsel is to the stabbing of gingiva, between the tooth of prior art, brush also has between the tooth that adopts soft macromolecular material to manufacture and brushes.Although it is soft that the head of brushing between tooth becomes, reduce the stabbing of gingiva, low because brushing intensity between this tooth, easily occur bending and deformation, deviation slightly while therefore aiming at teeth space, is just difficult to push teeth space, is difficult to successfully teeth space be cleaned.Therefore, use while brush between this tooth, require larger to the visuality of use procedure.

When teeth space for brush between the tooth of prior art between clean grinding one's teeth in sleep, exist light dark, be difficult for observing, the shortcoming that between tooth, brush is difficult to enter teeth space, easily stabs gingiva, the purpose of this utility model is to provide between a kind of tooth that can observe in real time and brushes, and is difficult for the shortcoming of observing to improve brush between existing tooth.
