When buying a Toothbrush, the first thing to look at is the size of the brush. The brush head is generally slightly smaller to ensure that it can flexibly rotate in the mouth. Children's mouth is small and the brush head needs to be smaller. In general, the size of the brush head depends on the individual situation, and it is necessary to take into account factors such as the size of the mouth, the degree of mouth opening and personal habits. There is no uniform standard. The American Dental Association recommends that adult toothbrushes should be: brush heads about 2.54-3.18 cm long, about 0.79-0.95 cm wide; 2-4 rows of bristles, 5-12 bundles per row. However, adults can also choose a brush head 2.3 cm. Long, 0.8 cm wide Children'S Toothbrush.
Second, it depends on the soft and hard bristles. The bristles should be moderately soft or slightly soft. But be careful, too soft hair is not easy to brush. The previous bristles were made of bristle, very hard, and easily damaged teeth and gums. They have been basically eliminated; the current bristles are mostly made of nylon. Specifically, it can be divided into two types - ordinary silk and DuPont. DuPont silk has good elasticity and is not easy to pour.
Third, sanding is also important. After the bristles are cut, if they are not smoothed, they are easily damaged by too sharp. A rounded brushed toothbrush can prevent this damage and protect the gums.
At the same time, the doctor reminds everyone that the toothbrush should be replaced every 3 months. Excessive use time, bacteria accumulate in the hair, which is not good for oral health. People who use DuPont silk bristles should not replace the toothbrush because the bristles are not falling.
In addition, the brush head is square or diamond-shaped, the upper edge of the bristles is flush or wavy, and the handle is curved and straight, which has no effect on the brushing effect. It is good to brush your teeth with the most common straight shank toothbrush.
Electric Toothbrush for special people
Since the electric toothbrush has entered the Chinese market, it has gradually been favored by people because of its convenient and labor-saving features.
There are two types of electric toothbrushes, namely ordinary electric toothbrushes and sonic vibrating toothbrushes. Old people, children or people with physical disabilities are recommended to use ordinary electric toothbrushes. But the effect of this type of toothbrush should not be too superstitious, as long as the brushing method is correct, the manual toothbrush is just as good as the ordinary electric toothbrush. Relatively speaking, the sound wave vibrating toothbrush has a stronger health effect, and it can rush out the residual food in the teeth by sound waves. This effect is a massage type, a whirlwind type, a front type... a large number of toothbrushes on the supermarket shelves, many people There are such questions: "The propaganda words of each toothbrush say that they have unique effects. Which kind of toothbrush is most suitable for you?" In this regard, the dentist said: the brush head is small, the brush is soft and moderate, and the brush is treated. Toothbrushes work best.
Brushing Interdental Brush
The teeth have a total of five faces, and the outer side, the inner side and the bottom side are easier to brush, but the two faces opposite to the adjacent teeth are difficult to brush, and some auxiliary tools - interdental brush or floss are needed. If the teeth are large, you can use the interdental brush. This is a small brush similar to a bottle brush. The brush head is made of fine nylon wire and stainless steel wire, which can be inserted into the teeth to remove residual food.
If the interdental space is small, it is not advisable to use the interdental brush. If it is stuffed in, it will damage the gums. At this time, floss is needed.
