Description

Title of the invention: Toothbrush with curved bristles

[0001] The present invention relates to a device of bristles on the toothbrush which are curved to allow a larger contact surface during brushing and to facilitate access to undercuts. The ends of said bristles are integrated into said brush head, thus forming a configuration of curved bristles. Said bristles have different directions of curvature. Said bristles have different lengths. Said bristles are arranged in different directions and in various numbers.

[0002] Brushing device,

[0003] said device comprising: • a) A brush head including curved bristles. • b) A handle allowing the brush head to be maneuvered. Characterized in that • c) The handle and the brush head can fit together and allow brushing when pressing on the brush head. • d) The handle and brush head are interchangeable.

[0004] Toothbrush bristles are straight. Since the contact surface is smaller, the tip wears out quickly.

[0005] Some brushes have bristles with different angles to adapt to different surface topographies but do not allow access to undercuts.
