ABSTRACT:
The present invention relates generally to implements for use in the practice of oral hygiene and pertains, more specifically, to a toothbrush for cleaning selected teeth with assistance provided by engagement of the toothbrush with further teeth opposed to the selected teeth.
In the pursuit of more effective oral hygiene practices, toothbrushes have undergone a great deal of development toward attaining increased effectiveness with ease of use. The present invention provides a toothbrush which enables such increased effectiveness, with ease of use. As such, the present invention attains several objects and advantages, some of which are summarized as follows: Provides a toothbrush having bristles configured and arranged for effective cleaning of teeth with the assistance of engagement of the toothbrush with teeth opposed to the teeth being cleaned; provides a toothbrush bristle configuration and arrangement combined with a contoured toothbrush surface configuration for enabling cleaning of selected teeth with the assistance of teeth opposed to the selected teeth; enables ease in cleaning surfaces of the teeth, while attaining more effective cleaning between teeth and adjacent the gum line, where the teeth meet the gums; effects advantageous gum massage, as well as tooth cleaning, through manipulations assisted by opposing teeth; provides a toothbrush which enables more effective oral hygiene practice without a vast departure from conventional practices which utilize a toothbrush, thereby encouraging widespread use; provides a toothbrush capable of being manufactured and sold at costs comparable to current conventional toothbrushes, while providing features far advanced over conventional toothbrushes.
The above objects and advantages, as well as further objects and advantages, are attained by the present invention which may be described briefly as a toothbrush for cleaning selected teeth while being assisted by corresponding opposed teeth in effecting cleaning manipulations, the toothbrush comprising: a manipulating member extending longitudinally between first and second ends; a handle adjacent the first end; a bristle support adjacent the second end; and a multiplicity of bristles extending altitudinally from the bristle support, the bristles being arranged in groups of bristles within a field of bristles having laterally opposite first and second edges, each bristle having a proximal end at the bristle support and a distal end remote from the bristle support, the field including at least a first group of bristles extending longitudinally adjacent the first edge of the field, and a second group of bristles extending longitudinally adjacent the second edge of the field; the bristles of the first group being curved between the proximal end and the distal end of each bristle to curve laterally away from the bristles of the second group; the bristles of the second group being bowed between the proximal end and the distal end of each bristle to curve laterally away from the bristles of the first group; and the bristle support having at least one support surface spaced transverse from the first and second groups of bristles, the support surface having a curved transverse cross-sectional configuration for engaging the opposed teeth while the toothbrush is manipulated for cleaning the selected teeth with the first and second groups of bristles, whereby the engagement of the curved support surface with the opposing teeth assists in creating cleaning manipulations in which the bristles of the first and second groups clean the selected teeth.
