What are the bristles of a toothbrush made of?

Most bristles are made of nylon filaments. Can be simply divided into-domestic brush and imported brush. Imported brush wire has good elasticity and is not easy to deform. The material of sharpened steel wire is PBT. Sanding is also important. After cutting, if the bristles are not smooth, they are easy to be too sharp and cause injuries. A grinding toothbrush with a round bristle tip can prevent this injury and has a stronger protective effect on gums.

Traditional toothbrushes are usually straight-handled and easy to use. The curved handle can go deep into the mouth where it is difficult to brush your teeth. It is said that the elastic handle can prevent the gums from being damaged by the excessive pressure of the toothbrush on the gums. Non-slip handle to prevent the toothbrush from slipping when brushing. In fact, the brushless handle design has a special effect of cleaning teeth.

There is a special emphasis on choosing a toothbrush, and children must choose according to their age.

The arrangement of bristles can also be divided into flat cut type, wavy type, V type and full contact type. Different bristle arrangements have different effects, but the key to tooth cleaning is the way of brushing teeth. As long as the correct brushing method is used, whether using traditional flat-cut bristles or improved wavy and full-contact bristles, dental plaque can be effectively removed and the accumulation of dental plaque on the tooth surface can be avoided, resulting in redness, swelling and pain of gums.

The design of 1 and V-shaped bristles is very beneficial to orthodontic people. It is characterized in that the central part of the bristles is concave and the two sides are convex. The bristles in the middle of the toothbrush surface are lower than those on both sides and are V-shaped. In this way, when brushing teeth, it not only effectively cleans the tooth surface, but also protects the appliance, effectively avoiding the difficulty of thoroughly cleaning teeth due to the obstruction of the appliance.

2. The mechanism of mechanical transmission toothbrush is to simulate manual brushing. Although there is no obvious difference in cleaning effect under the same conditions, it can ensure the cleaning efficiency better than manual brushing, effectively remove dental plaque and improve gum health, and has obvious advantages in controlling people with poor oral hygiene compliance.

3. In addition to the mechanical cleaning function, sonic vibration toothbrush is considered to enhance the removal of dental plaque and subgingival bacteria through sonic vibration.

4, soft hair: the advantage is that the damage to teeth and gums is small, which is more suitable for the general population, but too soft bristles may not play the best role in cleaning the tooth surface. Therefore, ordinary people can choose a soft toothbrush without excessively pursuing softness and delicacy. The bristles of children's toothbrushes need to be softer than those of adult toothbrushes.
