FIELD: personal use articles.
SUBSTANCE: invention relates to a toothbrush with needle-shaped bristles. The application describes a toothbrush with needle-shaped bristles located on its head, formed so that the difference in height between the longer and shorter bristles is from 1 to 4 mm, the ends of the longer bristles have a diameter of from 0.01 to 0.03 mm, the ends of the shorter bristles have a diameter of from 0.03 to 0.08 mm, the pointed part length of the longer bristles range from 4 to 8 mm and the pointed part length of the shorter bristles range from 2 to 6 mm, and the difference in length of the pointed part between the longer and shorter bristles is 1 to 4 mm. The toothbrush proposed in the invention provides excellent contact force with the teeth and gums, unique for a toothbrush with needle-shaped bristles, and at the same time provides excellent cleaning efficiency of the tooth surface due to the action of the shorter bristles having a relatively large diameter at the tips and the relatively short length of the pointed parts.
EFFECT: due to the shorter bristles the abrasion of the end part of the bristles slows which gives the effect of increasing the service life of the toothbrush.
