the selection of brush head can be appropriately small.
When buying a toothbrush, you should first look at the size of the brush head. Many people who travel or live in Japan will notice that toothbrushes provided by hotels or sold in supermarkets are one-third to one-half smaller than those commonly used in China. As a specialist, experts also tend to recommend toothbrushes with smaller brush heads to readers, while children’s toothbrushes are smaller. This is because the space in the posterior tooth area of the mouth is small, and it is difficult for the large brush head toothbrush to enter the posterior molar area, which will become a dead corner.
When dentists treat patients, they always find that the cleanness of the teeth at the back is worse, and the amount of soft dirt, plaque and calculus is more than that in other areas. The toothbrush with brush head can rotate flexibly in the mouth and reach all parts of the teeth, so it is not easy to leave sanitary blind spots.
Of course, the specific size of the brush head should also be different from person to person, and we can’t blindly pursue small size. We need to comprehensively consider factors such as the size of the mouth and the degree of mouth opening. The American Dental Association suggests that the adult toothbrush should be: the brush head is about 2.54-3.18 cm long, about 0.79-0.95 cm wide, and 2-4 rows of bristles. However, adults can also choose a children’s toothbrush with a brush head of 2.3cm long and 0.8cm wide.
the general population should choose soft toothbrush
The shape of the brush head is square and diamond, and the arrangement of the bristles is flat, wavy or V-shaped. As long as it is used correctly, it can effectively clean the teeth.
As for the soft and hard bristles, toothbrushes can be divided into medium hard bristles and soft bristles. The soft bristled toothbrush has the advantage of little damage to teeth and gums, but the disadvantage is that it can’t completely remove thicker plaque, and the cleaning efficiency is not high enough. Although the medium hard bristle toothbrush has a better cleaning effect on teeth, it also has a greater abrasion and damage to teeth. If you brush your teeth too hard, you may also damage your gums and even your teeth.
suggestions –
the general population uses soft toothbrushes;
People who have the habit of smoking, drinking coffee and tea can use a medium hard bristled toothbrush if their teeth are pigmented;
The bristles of the children’s toothbrush are softer than those of the adult toothbrush.
In addition, pay attention to whether the bristles have been brushed. If the brush hair is not polished after cross cutting, it is easy to cause gum damage due to sharp edges. A brushed toothbrush with rounded bristles can prevent this injury and has a stronger protective effect on gums. After buying a new toothbrush, first touch the end face of the bristles with your hands to see if there are sharp, burr and other feelings.
After each brushing, wash the toothbrush, put the brush head upward into the cup and place it in a ventilated and dry place. It is generally believed that the bristles should be replaced when they are deformed, but even if there is no obvious deformation of the bristles, the toothbrush should be replaced after about three months of use, because after a certain period of time, the bristles will age and denature, and the elasticity and hardness will change. In addition, if used for too long, bacteria will accumulate in the bristles, which is harmful to oral health.
the toothbrush in the hotel is too poor, so it is recommended not to use it.
When we go on business or travel, we often use the disposable toothbrush provided by the hotel to save money. According to the expert, he has paid special attention to the toothbrushes in hotels. Most of the toothbrushes provided by hotels are of very poor quality, even inferior to the cheapest toothbrushes sold in stores. He suggested that people should take their own toothbrushes when they go out, not to use the toothbrushes of hotels, and not to take the toothbrushes of hotels home for use.
the electric toothbrush has high cleaning efficiency.
The electric toothbrush is more expensive than the manual toothbrush, and the cleaning effect is not significantly different, but the cleaning efficiency is high, and the brushing time can be saved.
Most electric toothbrushes have a time reminder function, which can effectively ensure the brushing time and ensure the brushing effect. The electric toothbrush rotates at a fast speed. The skill of using the electric toothbrush is different from that of ordinary toothbrushes. If it is not used properly, it may easily damage teeth. You must learn it slowly when you first use it.
Electric toothbrushes mainly have mechanical transmission and acoustic vibration. It is believed that the acoustic vibration toothbrush can also produce cleaning effects where the bristles do not reach, but there is no evidence that acoustic waves can produce better cleaning effects.
