In fact, people have a misunderstanding when choosing a toothbrush, thinking that the softer the toothbrush material, the better, so it is not easy to hurt the gums. In fact, it is not easy to master the strength of brushing with a soft toothbrush, and the brush is too light to remove food residues and bacteria in the mouth; Excessive force will damage the gums and shorten the service life of the toothbrush. Most of the gum injuries are due to the irregular shape of the toothbrush used for a long time, which is easy to puncture the gums. Soft-bristle toothbrushes are more prone to deformation, so it is recommended not to choose soft-bristle toothbrushes because our gums are not so delicate.

Generally speaking, it is more appropriate to choose a toothbrush with moderate softness and a small electric toothbrush head. The width of the toothbrush head is moderate: adults generally do not exceed 4 rows and children do not exceed 3 rows of bristles; Moderate length: generally covering 2-3 tooth surfaces, which is beneficial to comprehensive consideration when brushing teeth and gargling. In addition, the solution of toothbrush scrub is also very important. If the bristles are not round after laser cutting, it is very easy to be too sharp and endanger dentistry.

Theoretically, the medical community has not made statistical analysis and investigation on the bactericidal effect of toothbrush and its actual effect on tooth maintenance, but only by mastering the correct brushing method can we achieve the purpose of cleaning teeth. Generally, the vertical brushing method is adopted, that is, when brushing the inside and outside of teeth, the bristles are parallel to the long axis of teeth, biased to the gums, and rotated under pressure along the gap between teeth, and brushed from top to bottom and from bottom to top.

When brushing the occlusal surface of teeth, it can be thoroughly cleaned by transverse short brush, and a certain working pressure must be added to make the tea end of the toothbrush enter the pit and fissure space of the occlusal surface of teeth and move horizontally along the arch target. It should also be noted that the enamel layer at the end of the final tooth in malocclusion, that is, the side near the throat, is not necessary to be ignored. If the toothbrush head can't be put in, the electric toothbrush head can be brushed out by rotating it. When cleaning the junction of teeth and gums, repeat 5-6 times in the same position with a little force. Finally, I would like to remind everyone that it is best to replace the toothbrush once every three months, otherwise the bristles will easily accumulate germs and will be bad for dental health.
