Method for brushing teeth and a toothbrush used for the same

Abstract

The inventor rejected the conventional method for brushing teeth with the brush head being parallel to the alignment of the teeth and found that a method for brushing teeth in the left and right direction in such a state that the brush head 21 is inclined relative to the alignment of the teeth can provide greater brushing effects as compared to the conventional method for brushing teeth with the brush head being parallel to the alignment of the teeth. The method for brushing teeth according to the present invention is a method for brushing teeth in the left and right directions in such a state that the brush head 21 is slightly inclined at an angle of 40° or less.

AI Technical Summary

Benefits of technology

The inventor found that brushing teeth in a way that the brush head is inclined relative to the teeth alignment can provide better results compared to the conventional method where the brush head is parallel to the teeth alignment. This is because the force needed to remove food particles from between the teeth works more effectively when the brush head is inclined at an angle of up to 35 degrees. The brush head is designed with a length that is two times greater than its width, which allows for a necessary length protruding to the side to sufficiently cover the contact width in the vertical direction of the teeth. This design allows for a more effective method of brushing teeth.

Problems solved by technology

The head of a conventional toothbrush is provided linearly from the main body of the toothbrush, and therefore, a conventional tooth brushing operation, which is brushing in the left and right directions, poorly removes food particles remaining between the teeth and between the teeth and the gums.

It should be noted, however, that the method for brushing teeth with the inclined toothbrushes disclosed in all of these publicly known documents is a method for brushing teeth in the left and right directions in such a state that the brush head is parallel to the alignment of the teeth and not a method for brushing teeth in the left and right directions in such a state that the brush head is inclined relative to the alignment of the teeth.

These minor improvements in the brush, however, may contribute to an increase in the performance of the brush to a certain extent but are insufficient in improving the performance to a great extent.

b. Teeth can be brushed with almost no burden being felt in the grip, though some twisting force from the main body is received by the user during brushing due to the inclination of the brush head, which is a problem that is not caused mechanically with the conventional linear brush heads and becomes greater as the amount of protrusion to the side increases.
