Selection of brush head can be appropriately small
When buying a toothbrush, first of all, the size of the brush head should be considered. It is recommended to choose a smaller brush head and a smaller children’s toothbrush. This is because the space of the posterior teeth of the oral cavity is small, and it is difficult for the large brush head toothbrush to enter the posterior molar area, which will become a dead corner.
Dentists always find that the cleaner the back teeth are, the more soft dirt, plaque and calculus they have. The toothbrush of the brush head can rotate flexibly in the mouth and reach all parts of the teeth. It is not easy to leave a hygienic corner.
Of course, the specific size of the brush head also varies from person to person, and can not blindly pursue small, need to take into account the size of the mouth, the degree of mouth opening and other factors. The American Dental Association suggests that adult toothbrushes should be 2.54-3.18 cm long, 0.79-0.95 cm wide and 2-4 rows of bristles. But adults can also choose children’s toothbrushes 2.3 centimeters long and 0.8 centimeters wide.
Soft-furred toothbrushes are available for the general population
The shape of the brush head is square and diamond, and the arrangement of the brush bristles is flat, wavy or V-shaped, which can effectively clean teeth as long as it is used correctly.
As for the soft and hard bristles, there are two kinds of toothbrushes: medium and hard bristles and soft bristles. Soft hair toothbrush has the advantage of less damage to teeth and gums, but the disadvantage is that the thicker plaque can not be completely removed and the cleaning efficiency is not high enough. Although medium-hard hair toothbrush has better cleaning effect on teeth, it also has greater wear and damage to teeth. Too much brushing force can also cause damage to gums and even teeth.
Suggestions on Selection of Special Population
People who smoke, drink coffee, and drink tea can use medium-hard toothbrushes if their teeth are pigmented; children’s toothbrushes have softer bristles than adults’toothbrushes.
In addition, pay attention to whether the brush has been ground or not. If the brush is not polished after the cross section, it is easy to cause gingival injury because of sharp edges. The brush with rounded bristles can prevent this kind of injury and has stronger gum protection effect. After buying back the new toothbrush, first touch the end of the brush with your hand to see if there are any sharp, burr and other sensations.
Frequency of toothbrush replacement
After each brush, the toothbrush should be washed, the head of the brush should be put up in the cup, and placed in a ventilated and dry place. It is generally believed that when the brush is deformed, it should be replaced, but even if the brush has no obvious deformations, it should be replaced for about three months, because after a certain period of time, the brush will be aged, denatured, and the elasticity and hardness will change. In addition, the use of long time, brush hair accumulation of bacteria, not conducive to oral health.
