The choice of brush head can be appropriately small
When you buy a Toothbrush, you must first look at the size of the brush head. Many people who travel or live in Japan will notice that the toothbrushes sold by hotels or supermarkets are one-third to one-half smaller than those commonly used in China. As a specialist, experts also tend to recommend readers with smaller brush heads and smaller children's toothbrushes. This is because the space in the posterior region of the mouth is small, and it is difficult for the large brush head toothbrush to enter the posterior region of the molar, and the area becomes a dead angle.
When dentists treat patients, they always find that the lower the degree of cleanliness of the teeth, the more soft dirt, plaque, and tartar than other areas. The toothbrush of the brush head can be flexibly rotated in the mouth to reach various parts of the tooth, and it is not easy to leave a sanitary corner.
Of course, the specific size of the brush head also varies from person to person, and it cannot be pursued blindly. It is necessary to consider factors such as the size of the mouth and the degree of mouth opening. The American Dental Association recommends that adult toothbrushes should be: brush head length of about 2.54 - 3.18 cm, width of about 0.79 - 0.95 cm, bristles 2-4 rows. However, adults can also choose a brush that is 2.3 cm long and 0.8 cm wide.
Ordinary people should choose soft hair toothbrush
The brush head has a square shape and a diamond shape, and the bristles are arranged in a flat, wavy or V shape, and the teeth can be effectively cleaned as long as they are properly used.
As for the soft and hard bristles, the toothbrush has a medium-hard toothbrush and a soft-bristled toothbrush. The soft-bristled toothbrush has the advantage of less damage to the teeth and gums. The disadvantage is that the thick plaque cannot be completely removed, and the cleaning efficiency is not high enough. Although the medium-hard toothbrush has better cleaning effect on teeth, it also has a large wear and damage to the teeth. When the brushing force is too strong, there is a risk of damaging the gums and even the teeth.

Ordinary people use soft-bristled toothbrushes;
If you have a habit of smoking, drinking coffee or drinking tea, you can use a medium-hard toothbrush if your teeth are pigmented.
The bristles of children's toothbrushes are softer than adult toothbrushes.
In addition, pay attention to whether the bristles are treated with sanding. After cross-cutting, if the bristles are not polished, it is easy to cause gum damage due to sharp edges. A rounded brushed toothbrush can prevent this damage and protect the gums. After buying a new toothbrush, touch the end of the brush with your hand to see if there is any sharpness or burr.
After each brushing, the toothbrush should be washed, put the brush head up into the cup, and placed in a dry and ventilated place. It is generally believed that the bristles should be replaced when deformed, but even if the bristles are not significantly deformed, the toothbrush should be replaced after about three months. Because the toothbrush is used for a certain period of time, the bristles are aged, denatured, and the elasticity and hardness are changed. In addition, if the use time is too long, the bacteria accumulate bacteria, which is not good for oral health.
Hotel Toothbrush is too bad to recommend
When we are on a business trip or travel, we often use the disposable toothbrush provided by the hotel to save trouble. According to experts, he paid special attention to the hotel's toothbrushes. Most of the hotels provided toothbrushes are of very poor quality, even less expensive than the cheapest toothbrushes sold in stores. He suggested that you should bring your own toothbrush when you go out, don't use the hotel's toothbrush, and don't take the hotel's toothbrush home.
Electric Toothbrush cleaning efficiency
Electric toothbrushes are more expensive than manual toothbrushes, and there is no significant difference in cleaning effect, but the cleaning efficiency is high, which can save brushing time.
Most electric toothbrushes have a time reminder function, which can effectively guarantee the brushing time and ensure the brushing effect. The electric toothbrush rotates at a fast speed. The skill of using an electric toothbrush is different from that of a normal toothbrush. If it is used improperly, it may easily damage the teeth. You must learn slowly when using it for the first time.
Electric toothbrushes mainly include mechanical transmission and sonic vibration. It is believed that the sonic vibration type toothbrush can also produce a cleaning effect where the bristles do not reach, but there is no evidence that the sound wave can produce a better cleaning effect.
