<p>A tooth cleaner capable of changing direction includes a rod-shaped force-applying unit (10) for user holding and force-applying and a tooth-picking unit (20) pivotally connected at the side of the force applying unit (10). The tooth-picking unit (20) is capable of rotating relative to the force-applying unit (10) and therefore changing direction, such that a dental floss (21) on the tooth-picking unit (20) is tilted from the force-applying unit (10) at different angles, which enables a user to clean teeth at different positions</p> |
