Description

The present invention relates to a toothbrush for cleaning mesial and / or distal tooth surfaces, comprising a brush head for receiving cleaning bristles and a brush handle for its handling.

Mesial and / or distal tooth surfaces of a gap dentition are usually difficult or impossible to achieve by the cleaning bristles of a commercial toothbrush. This can lead to carious diseases and attacks on the tooth, which often lead to tooth loss.

Object of the present invention is to provide a toothbrush, can be achieved with the mesial and / or distal tooth surfaces, cleaned and maintained.

This object is achieved by the features specified in claim 1, in particular by a toothbrush having a brush head, which has an angling relative to the brush handle. The brush head can have an internal bend, in which the cleaning bristles are arranged on the brush handle pointing to the brush head. The cleaning bristles can be different lengths.

In another embodiment, the brush head has an outer bend, in which the cleaning bristles are arranged by the brush handle pioneering on the brush head.

In another embodiment, these inventive measures are used in an electric toothbrush, wherein the brush head is an oscillating oscillating oscillating motion exporting oscillating head. The brush handle may have a longitudinal cavity in which a drive means for driving the oscillating head extends.

In another embodiment of the toothbrush according to the invention, the cleaning bristles are arranged in a U-shape on the brush head, and the brush head can also be provided with a U-shaped recess, along which the cleaning bristles extend and are connected to the brush head.
