Toothbrush

Abstract

A toothbrush is disclosed, in which wing hairs are arranged in a V-shape in left and right sides with respect to the center hairs which are the center toothbrush hairs planted in forward and backward directions in a toothbrush head, and the V-shaped wing hairs of the left and right sides are arranged in a X-shape, and auxiliary hairs are arranged between the forward and backward wing hairs in part of the X-shaped toothbrush hairs. With the above arrangements, a contact surface area of each tooth is widened, and a more effective tooth brushing can be performed in three fossas (mesial fossa (mesial pit), a central fossa (central pit) and a distal fossa (distal pit)), a buccal developmental groove, a lingual developmental groove, an accessory groove, a triangular groove and a buccal groove of a buccal aspect, which correspond to a dental caries portion, an interproximal space in which a food debris might be accumulated, and a contact area peripherals of a buccal aspect in which a food debris might be impacted, so dental caries and tooth diseases (periodontitis) can be advantageously prevented, and a pain due to a temporomandibular disorder and a facial muscle fatigue might be reduced and recovered by protruding a cushion layer from an upper side of a toothbrush.

Description

CLAIM OF PRIORITY[0001]This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. §119 from an application earlier filed in the Korean Intellectual Property Office on 21 Dec. 2007 and there duly assigned Serial No. 2007-0135327.TECHNICAL FIELD OF THE INVENTION[0002]The present invention relates to a toothbrush which is able to significantly reduce dental caries, periodontitis, pain due to temporomandibular disorder or the like which are known as three dental diseases, and in particular to a toothbrush featured in that wing hairs are arranged in a V-shape in left and right sides with respect to the center hairs which are the center toothbrush hairs planted in forward and backward directions in a toothbrush head, and the V-shaped wing hairs of the left and right sides are arranged in a X-shape, and auxiliary hairs are arranged between the forward and backward wing hairs in part of the X-shaped toothbrush hairs. With the above ar...

AI Technical Summary

Benefits of technology

[0008]The present invention is advantageously characterized in that toothbrush hairs are arranged in a V-shape in left and right sides with respect to a central hair which is a central toothbrush hair in the forward and backward directions of a toothbrush head, and the V-shaped toothbrush hairs of the left and right sides are arranged in a X-shape, and an auxiliary hair is arranged between the front and rear wing hairs of the second and fifth toothbrush hairs. The above construction well matches with a concave structure (fossa, accessory groove, triangular groove, buccal developmental groove, lingual developmental groove, buccal groove of a buccal aspect) of a tooth which corresponds to a dental caries portion. In addition, it is possible to more effectively remove the accumulation of food debris and to more effectively brush an interpoximal space having a poor brushing effect, and a contact area that a food debris might be easily impacted therein.

[0009]In addition, a pain due to a temporomandibular disorder and a facial muscle fatigue might be reduced and recovered by protruding a cushion layer from an upper side of a toothbrush.

[0010]Since a barrier wall is formed between toothbrush hairs for thereby preventing an inclination of toothbrush hairs, and a toothbrush brand might be formed therein.

Problems solved by technology

However, the conventional toothbrush is formed in a straight arrangement structure in a leftward and rightward direction of a head, so a tooth contact surface area is narrow, and an effective tooth brushing work cannot be performed with respect to a concave portion of a molar occlusal aspect.

In addition, it is impossible to effectively brush an interproximal space in which a molar buccal aspect food debris is accumulated, and a buccal contact area peripheral in which a food debris might be impacted.
