The present invention relates to the hygiene means and is intended for cleaning teeth and interdental spaces.

RU P&ient No. 2420248 (priority date 16.03.2010} discloses a dental stick consisting of a rod-like base, at the opposite end of which massaging and cleaning elements are arranged. Both sides of the elongated oval shaped rod-like base are provided with a system of recesses uniformly made over the entire length thereof. One of the ends is provided with a wedge-shaped massaging element having a ridged surface. An opposite end accommodates a cleaning element having a smaller oval cross-section compared to that of the base and provided with protrusions, being perpendicular to the base symmetry axis, and with spherical radii. The cleaning element and protrusions are made elastic and flexible.

Disadvantages of the prior art solutions are as follows:

- lack of a pointed tip resulting in lower cleaning efficiency;

- small number of protrusions also resulting in lower cleaning efficiency.

The published PCT US2008Q251098 also discloses a dental stick consisting of a rod, bristles and a coating.

Disadvantages of the prior art solutions are as follows:

- lack of a pointed tip at the dental stick end resulting in iower cleaning efficiency;

- random arrangement of bristles resulting in Iower cleaning efficiency;

- only one end of the denial stick is usable;

- only one type of cleaning is possible resulting in Iower cleaning efficiency. The technical results to be accompiished based on the asserted invention are as follows:

- a more efficient removal of dental plaque and food debris from teeth and interdental spaces of a mouth cavity both on the outside and inside of the feeth;

- an efficient use of both ends of the dental stick;

- the denial stick is shaped as an elongated prism to allow a firm grip thereof by a hand;

~ the bristles are made from a plurality of thin cylindrical fibers which contributes to the higher strength thereof and longer service life of the dental stick; - the bristles are made in fines, thereby increasing cleaning efficiency:

- the bristles are arranged spirally, thereby allowing the cleaning process to be made continuous.

The essence of the asserted technical solution expressed by a combination of essential features thereof resides in the fact that the technical result to be accomplished is to be realized using the variants of the provided dental stick comprising an elongated body, one end of which is made pointed, while cleaning elements shaped as bristles are arranged at the second end.

Characteristic essential features of the invention allowing the above result to be accomplished consist in that one end of the dental stick is provided with a tip, the bristles are arranged orderly, perpendicular to the body of the dental stick and are equally spaced from each other and between the bristle lines, the number of bristles exceeds four improving thereby the cleaning process. Making the dental stick shaped as an elongated prism according to some variants allows the dental stick to be firmly gripped by hand. Arranging the bristles spirally according to one of the variants allows for a continuous cleaning process. The bristles are made from a plurality of thin cylindrical fibers which contributes to the higher strength thereof and longer service life of the dental stick. The body of the dental stick and bristles are made from a resilient material. The dental stick tip Is aiso made from a resilient material, such as rubber.

The body of the dental stick is shaped as an elongated prism (right parallelepiped), which takes the form of an equilateral pyramid on one side (Fig. 5, 6). A single line of bristles is arranged on the opposite side of the dental stick body, on an edge of two front faces thereof.

The essence of the asserted device according to the fourth variant is represented by the same combination of features like in the first variant, except as is specified below. The body of the dental stick is shaped as an elongated prism (right parallelepiped), which takes the form of an equilateral truncated pyramid on one side (Fig, 7, 8). A pointed tip is attached to the end of the pyramid. Two lines of bristles are arranged on the opposite side of the body of the dental stick, with the bristles lines being arranged along two front faces of the body of the dental stick and are parallel to each other.

The essence of the asserted device according to the fifth variant is represented by the same combination of features like in the first variant, except as is specified below. The body of the denial stick is shaped as an elongated prism (right parallelepiped), which takes the form of an equilateral truncated pyramid on one side (Fig. 9, 10). A pointed tip is attached to the end of the pyramid. A single fine of bristles is arranged on the opposite side of the dental stick body, on an edge of two front faces thereof.

The essence of the asserted device according to the sixth variant is represented by the same combination of features like in the first variant, except as is specified below. A pointed tip is not attached to the end of the cone (Fig. 11 , 12).

The essence of the asserted device according to the seventh variant is represented by the same combination of features like in the first variant, except as is specified below. The bristles are arranged spirally. Spiral turns are equally spaced from each other (Fig. 13, 14).
