2021-09-15

1.Size of toothbrush head: according to the regulations of the American Dental Association, the length of the toothbrush head shall be 2.5 ~ 3cm, the width shall be 0.8 ~ 1cm, there are 2 ~ 4 rows of bristles, 5 ~ 12 bundles of bristles in each row, and the front end of the toothbrush head shall be round and blunt. These regulations can be used as a reference for people to choose toothbrushes.

2.Toothbrush's Hardness of bristles: generally, it can be divided into soft, neutral and hard. It is more suitable to use a toothbrush with neutral hardness at ordinary times. When buying a toothbrush, you can press the bristles with your fingers. If your fingers have a tingling feeling, it means that they are too hard to use. The bristles of commercially available toothbrushes are mostly nylon bristles. The elasticity, uniformity and hardness of nylon bristles are better than pig hair toothbrushes, which is more conducive to oral health care.

3.Angle between brush head and brush handle: there are two types of commercially available toothbrushes: linear type and angle type. The linear toothbrush is more powerful when used. The toothbrush with an angle has a better cleaning effect on the rear teeth. The angle should be 17 ~ 20 degrees.

4.Top of bristles: the top of each bristle should be round and blunt without acute angle. It can be judged by hand when purchasing.

5.Special toothbrush: Patients with periodontal disease or older people have shrinking gums and increased tooth space. In addition to the general toothbrush, the interdental toothbrush should be used. The bristles of this toothbrush have conical and long strip shapes, which can be used optionally. There is also a toothbrush with only two rows of bristles, which is used to massage the gums. The concave toothbrush with the outer two rows of bristles longer than the middle two rows of bristles is specially used for those undergoing orthodontic treatment. This toothbrush can not only clean the tooth surface, but also clean the food residue on the orthodontic device. For those with inconvenient hand and foot movement (such as stroke patients), electric toothbrush, light energy electric ion toothbrush, etc. can be selected.
