Description

Toothbrush

Technical field

The present invention relates to a kind of toothbrush, but relate in particular to a kind of toothbrush of inner surface of the cleaning teeth with special angle.

Background technology

The health of tooth health and whole body has firm inseparable relation, so the modern more and more payes attention to the importance of " Prevention is better than cure ", to set up good oral hygiene and healthy tooth.In general, the tooth health pattern has just formed foundation in early days, if be negligent of looking after in the formation phase, then can lose the assets of its health, though accept again the repairing of good technology thereafter or wear artificial tooth, also can't be comparable with natural teeth.

By many medical science reports as can be known, the tooth inner face takes place to start from usually in decayed tooth.The handle structure of the traditional toothbrush that present known market is common generally mostly is straight shape and bristle direction perpendicular to straight lever, and perhaps handle structure has bending a little.It is very clean that these traditional toothbrush can be cleared up the tooth outer surface, yet the higher tooth inner surface of decayed tooth incidence but can't be cleaned out easily.This is because the operation that the structure of traditional toothbrush lever makes hand grip causes restriction on degree, therefore can't clean effectively for more hidden inboard tooth and cause.

In addition, the bristle of traditional toothbrush head mostly is and combines with toothbrush body and be single pattern.At the different flank of tooth of cleaning and teeth crevice, the toothbrush of selling can't carry out corresponding replacing with bristle according to individual other otherness at present.

The prophylaxis of teeth decayed tooth needs to rely on the attention of individual to health care usually, so the selection of toothbrush is very important.Yet according to present toothbrush on the market, the doctor only can provide the selection suggestion about bristle or lever etc. usually.Therefore, because still there is above-mentioned shortcoming in traditional and known at present toothbrush, the present invention has carried out the research improvement to this.
