What's the difference between soft hair and medium hair of a toothbrush? Who is suitable for each?

The difference between the diameter and thickness of bristles is that the thicker the bristles are, the harder the bristles are and the softer the bristles are.

Soft-bristle toothbrushes are not harmful to the oral cavity, while hard-bristle toothbrushes are easy to hurt the gums. Soft toothbrush can remove dental plaque from teeth, but it can't remove thick dental plaque and calculus; On the other hand, toothbrush with bristles can better remove dental plaque and calculus, but it will damage gums and wear teeth.

Application mode

The correct way to use a toothbrush is:

Wash the toothbrush thoroughly after each use and throw away the water as much as possible. Put the toothbrush head up in the mouthwash cup, or put it in a ventilated and sunny place to dry and disinfect.

If possible, you can buy two or three toothbrushes to use alternately at the same time, which can prolong the drying time of toothbrushes. This is especially important for patients with gingivitis and periodontitis. In addition, rotation can also maintain the elasticity of toothbrush bristles.

Old toothbrushes with messy or curled bristles must be replaced in time, otherwise it will be bad for teeth and gums.

Children who live in groups should concentrate on cleaning and disinfecting toothbrushes once a week.
