COMBINED TOOTHBRUSH AND GUM MASSAGE DEVICE |
摘要 |
<p>A dental hygiene device for toothbrushing and gum massage comprises an elongated handle on which a bristle carrying head is pivotable for movement between a first operating position in alignment with the length of the handle and a second operating position at right angles to the length of said handle, there being a rib and groove arrangement for locking the head in either of those positions during normal toothbrushing and/or gum massaging operations but being readily responsive to torque applied by a user to turn the head from one position to another. The head has a central area of tooth engaging hard bristles, with areas of softer bristles at the ends for effective gum massaging.</p> |
