- Teeth should be brushed with moving a brush up and down in order to brush the teeth correctly. If a habit of correctly brushing teeth is not formed at a young age, the arrangement of teeth becomes irregular. And if teeth are brushed from side to side that is in the horizontal direction due to the wrong habit of brushing teeth, germs and plaque is accumulated, and then dental caries and calculus sometimes occur on the edge part of tooth which is not brushed clean. Besides, a person with arm impairment may have difficulty in brushing teeth, though it is simple to brush teeth.
Vertical brush will solve these problems.
