Brush head and toothbrush with the brush head

Abstract

A brush head and a toothbrush with the brush head are provided. The brush head includes a body having a front end, a back end opposing the front end, and two opposite sides; and a brush member mounted on a surface of the body and being formed with a plurality of bristles, wherein the plurality of bristles define a brush surface that slopes in relation to the surface of the body. The brush surface of the bristles can closely abut against the teeth and the gingival sulcus, and the cleaning effect of tooth brushing is efficiently enhanced using the toothbrush with the brush head, thereby overcoming the drawbacks of the prior art.

Description

FIELD OF THE INVENTION [0001] The present invention relates to cleaning technologies, and more particularly, to a brush head and a toothbrush with the brush head for cleaning teeth. BACKGROUND OF THE INVENTION [0002] Healthy teeth not only allow people to eat normally but also enable people to fully enjoy delicacies during chewing. Various bacteria abound in the oral cavity where food is mixed with saliva, which, coupled with bacterial reactions, accounts for the formation of dental plaque in the gingival sulcus. Given time, the aforesaid reactions cause periodontal disease and dental caries. [0003] More particularly, pathogenesis of periodontal disease is as follows: dental plaque and bacteria in the gingival sulcus cannot be thoroughly cleaned; however, accumulation and calcification of dental plaque in the gingival sulcus lead to the formation of dental calculus, a dental term. Once dental calculus is formed, cleaning the gingival sulcus becomes more difficult, which is an initia...

AI Technical Summary

Benefits of technology

"The present invention provides a brush head and toothbrush with the brush head that can enhance the cleaning efficiency of tooth brushing, clean the gingival sulcus and teeth efficiently, make tooth brushing simple and easy, and meet the dual requirements for solving the inaccessibility problem and cleaning the occlusive surface. The brush head has a front end with a fixing portion and a back end with a second bonding portion, and the handle can be coupled to either the front or back end of the brush head. The bristles of the brush head have a plurality of lengths and the brush surface slopes in relation to the body of the brush head. The toothbrush with the brush head can be integrally formed or separately formed, and the brush head can be designed for different needs."

Problems solved by technology

Given time, the aforesaid reactions cause periodontal disease and dental caries.

More particularly, pathogenesis of periodontal disease is as follows: dental plaque and bacteria in the gingival sulcus cannot be thoroughly cleaned; however, accumulation and calcification of dental plaque in the gingival sulcus lead to the formation of dental calculus, a dental term.

Once dental calculus is formed, cleaning the gingival sulcus becomes more difficult, which is an initial symptom of periodontal disease.

Eventually, loss of periodontal alveolar bone and formation of periodontal pockets take place, resulting in severely loosened teeth and even tooth loss.

Even if the toothbrush 20 illustrated by FIGS. 3A and 3B and that proposed in Taiwanese Patent No. 264649 is adopted, it would be impossible to stretch the cheeks with the toothbrush, thus tooth brushing can only be carried out in a nearly parallel direction, and any attempt to remove dental plaque from the gingival sulcus and tooth surfaces is always ineffective.

However, none of the designs of the brush head based on the aforementioned known technology fulfills the dual requirements for solving the inaccessibility problem and cleaning the occlusive surface.

As described above, the designs of the brush head and bristles of the toothbrushes on the market greatly compromise the cleaning efficiency of tooth brushing.

The general public does not possess the oral cavity cleaning skills expected of dentists or dental professionals.
