## Abstract

Three toothbrushes designed to adapt to the 3 different mouth shapes (narrow, average, wide) is disclosed. The 3 specific bends in the handle make it possible for the brush to stay in contact with the teeth at the corners or bend of our mouth/arch. The unique contour and placement of bristles “hug” the tooth/teeth from the occlusal/incisal all the way to the gingiva, making adaption of the brush NOT technique sensitive. The toothbrush(s) design encourages the proper brushing method used by dental professionals.

## Claims

### Claim 1

1) The placement of 3 specific bend(s) in the handle:
The toothbrush(s) handle is specific to the SHAPE (narrow, average, wide) of your mouth, making it more effective in overall bacterial removal.
The 3 specific bends in the handle make it possible for the brush to stay in contact with the teeth and arch at the four corners of the mouth. The corner areas are a problem for recession due to hard, aggressive brushing, commonly the first stroke when entering the mouth, and also an area that is regularly missed or skipped on the lingual because the bend of our arch is awkward for bristle adaption.

### Claim 2

2) The bristle placement and head size is specific to our actual teeth sizes and shapes
Proper brushing method is accomplished with a bristle pattern of short and stiff bristles (6.1 mm) on the center rows (for the occlusals) and gradually longer, tapered bristles (8.5 mm, 10.3 mm, 12.1 mm) reaching the outer rows (for the gingiva). The head size consists of 76 tufts. The overall head size is 32.4 mm long and 11.8 mm wide.
The larger head size and increased amount of end rounded bristles, plus the specific arrangement of the bristle pattern makes the adaption of the toothbrush user friendly and not technique sensitive. This in return will encourage the proper 45 degree bristle placement and lower the incidence of tooth decay, periodontal disease, tooth loss and systemic heart disease, because the plaque and harmful bacteria will effectively be removed.
