INTERDENTAL BRUSH Technical Field The present invention relates to an interdental brush to remove foreign substances lodged between teeth, and more particularly to an interdental brush, the tip of whose steel wire, covered with brush hairs, is extended to form a guide tip of a certain length.

Background of the Invention To keep their teeth clean most people use an ordinary tooth brush, but ordinary brushes are found to insufficiently clean and remove the residual food caught in between the teeth, the tartar on the teeth, etc., and therefore the so-called interdental brushes have been in use.

In other words, to efficiently remove plaque, which may cause gingival disease, or prevent this progress, interdental brushes with thin brush hairs 30 attached in all directions to a steel wire 20 extending from its body 10, are used by some people.

To use an ordinary interdental brush one takes hold of its body 10 with one's fingers, inserts said wire 20 in between teeth, and moves it back and forth, thereby cleaning the gaps between the teeth. Inconveniences are encountered with these devices and method.

1. Because said wire is covered with hairs it is not so easy to insert it correctly between teeth.

2. When said wire fails correctly to locate the gaps between the teeth but knocks against gingiva, it may become crooked and render the brush unusable, or when it is forcefully driven and hits gingiva the gingiva itself can become injured.

3. Such interdental brushes are currently not very popularized with people. It is difficult to educate people as to the correct use of them.

Disclosure of the Invention The present invention has been conceived with the view of the improving the conventional interdental brushes, by remedying the above problems. This is done by providing a guide tip of a certain length, formed lengthwise, in an extension of the steel wire.

Brief Description of Drawings Fig. 1 is a perspective of a conventional interdental brush.

Fig. 3 is an illustration of the use of the interdental brush of the present invention.

Best Mode for Carrying Out the Invention Below, making reference to the drawings attached hereto, the interdental brush of the present invention is described in further detail. As illustrated in Fig. 2, the interdental brush of the present invention is made of a body 1 and a steel wire 3, extending from said body 1 and covered with hairs 2 in all directions, said steel wire 3 being extended to form at its end a guide tip 4 of 2-8 ~ 8 mm in length.

As seen in Fig. 3, said guide tip 4 will play the role of an efficient guide to conduct said steel wire 3 of said interdental brush correctly into the gaps between teeth. This renders the brush to be very convenient in use.

The interdental brush of such a construction, of the present invention, has the merits as are given below: 1. The interdental brush of the present invention makes it easy to locate it correctly between the teeth.

2. When the brush enters between the teeth, said guide tip plays the role of an effective guide.

3. As a result of the device's ability to locate between teeth and gingiva, it becomes unnecessary to apply extreme force to the brush when using it, and there is little risk of injuring gingiva.

4. It is possible to recognize the gap between the teeth at just one insertion of said guide tip.

5. Because the brush can smoothly be inserted in the gap between the teeth due to the effective guidance of said guide tip, said steel wire has little risk of getting crooked, thus prolonging the life span of a brush.

6. The guide tip, furthermore, can be modified according to the individual anatomical features of the user's teeth and gingival to provide individualized convenience for the user.
