1. Toothbrush containing a head (10), which is formed on the front longitudinal end of the handle (14) and which is equipped on its upper surface with a bunch of parallel hairs (18), and this brush contains a set of rods (20) made of elastomeric material, each of which runs essentially parallel to the hairs, and which are located essentially in two longitudinal rows on one or the other side of the hair bundle (18), characterized in that each row of these rods (20) contains high rods ( 20a), which are located in the longitudinal direction essentially in the central zone of the row, and which have a length exceeding the length of the hairs adjacent to them (18), and low rods (20e), which are located at the ends of the row and whose length is less than the length hairs located next to them (18).  2. Toothbrush according to claim 1, characterized in that it contains high rods (20a, 20b) of various lengths and low rods (20d, 20e) also of various lengths.  3. Toothbrush according to claim 1 or 2, characterized in that the tallest rods (20a) have a height that is less than the height of 25% of the hairs adjacent to them (18).  4. Toothbrush according to any one of the above items, characterized in that the lowest rods (20e) have a height, the value of which is at least 10% less than the height of the hairs adjacent to them (18).  5. Toothbrush according to any one of the above paragraphs, characterized in that in one row of rods the upper ends of these rods (20) are located along a curve whose concavity is directed downward.  6. Toothbrush according to any one of the above items, characterized in that the rods (20) have a cylindrical shape.  7. Toothbrush according to any one of the above paragraphs, characterized in that the rods have a diameter, the value of which is essentially enclosed in the range of 1 - 2.5 mm.  8. Toothbrush according to any one of the above paragraphs, characterized in that the rows of rods (20) extend in a forward direction beyond the outer limits of the hair bundle (18).  9. Toothbrush according to any one of the above paragraphs, characterized in that this brush contains at least one rod (20e) of small height, located in the longitudinal extension of the bundle of hairs (18).  10. Toothbrush according to any one of the above paragraphs, characterized in that each of the rods (20) is mounted on the head (10) of the brush using the lower base of the fixture (22), which enters the hole of the fixture (24) made in the housing heads (16), in that the fixing hole (24) opens with its two ends on the upper and lower (26) surfaces of the head housing (16), and also in that the fixing base (22) of this rod (20) protrudes in a downward direction from the bottom surface of the head housing (16) and thus formed m to interact with that bottom surface (26) so as to prevent an attempt to retrieve this rod (20) in an upward direction.  11. Toothbrush according to claim 10, characterized in that the upper and lower ends of the fastening base (22) are located above and below the upper and lower surfaces of the head housing (16), in that the ends of the fastening base are interconnected using a web of material (28), which extends outside the fastening hole (24) around the outer lateral edge (30) of the head housing (16), as well as the fact that at the level of the lower and upper ends of the fastening base (22), the material bridge (28) abuts against the lower and in the upper surface of the head housing (16) for th to ensure fixation of the rod (20) on the head (10).  12. Toothbrush according to claim 11, characterized in that the set of rods (20) is realized by molding or pressing as a single part, as well as the fact that the connection jumpers (28) of the rods (20) form a protective roller (32) of elastomeric material around the outer lateral edge (30) of the head housing (16).  13. Toothbrush according to claim 12, characterized in that the protective roller (32) is formed in a hollow lodgement made in the head housing (16) so that this roller (32) is at the same level as the outer surfaces head housings (16).  14. Toothbrush according to claim 12 or 13, characterized in that the lower surface (26) of the head housing (16) is covered with a film of elastomeric material, which is made of suitable material for this together with the rods (20).  15. Toothbrush according to any one of the above items, characterized in that the rods (20) are made of silicone elastomer.
