Title:
TOOTHBRUSH
Document Type and Number:
WIPO Patent Application WO/2018/141264
Kind Code:
A1
Abstract:
A toothbrush (30) includes a toothbrush head (32) with a new design and a handle (31) that operates to move the toothbrush head (32). The toothbrush head (32) has multiple types of purpose-designed bristle-bundles precisely mapped to target specifically all dental-gingival surfaces and anatomically niches, including various dead-corner niches/surfaces that are usually not accessible by currently existing toothbrushes. The toothbrush head (32) is designed to be inclined to accommodate both lingual and palatal surface. This toothbrush head (32) also functions uniquely by coupling over dental arches and rotating so that the toothbrush (30) does not need to be lifted during movement from one end to the other. Further, moving the handle (31) with respect to the toothbrush head (32) causes the width of the toothbrush head (32) to change to accommodate the different widths of the teeth.
