Misunderstanding of brushing teeth

misunderstanding 1: brushing teeth with cold water

cold water will cause toothache in people with dentin sensitivity, and is not conducive to the activity of effective substances in toothpaste. The main components of toothpaste are friction agent and fluoride. Laboratory research found that the best temperature for these effective components to play a role is about 37 ℃[ 1]

suggestion: when brushing teeth, it is best to use warm water close to your body temperature.

expert comments: it’s best to brush your teeth with warm water.

brushing your teeth with cold water will cause tooth sensitivity and pain. Especially in winter, you need to brush your teeth with warm water to avoid tooth sensitivity. The temperature of warm water should be close to the body temperature, and too hot water is not good.

Myth 2: brush your teeth too hard

too much force when brushing your teeth may hurt your teeth.

suggestion: 200 grams of force is enough, which is about the force of fingers picking up a popsicle and brushing teeth with the force of wrist instead of arm.

it is also correct not to use too much force when brushing your teeth. It is not that the more vigorous you use, the better you can brush your teeth. If you brush your teeth in the wrong way, the more strength you use, the easier it is to hurt your teeth. However, the force used for brushing varies from person to person, and there is no quantitative standard. Brushing teeth is not light or heavy. It is appropriate to brush the tooth surface. Everyone can take it according to their own situation.

misunderstanding 3: brushing teeth horizontally

the survey shows that more than 90% of Chinese people brush their teeth horizontally, which is a kind of physical wear on enamel. On the one hand, horizontal brushing can not remove the garbage in the tooth gap. At the same time, it may also lead to wedge-shaped defect of tooth root, gum damage, dentin sensitivity and other problems.

Selection of toothbrush

the basic principles of selecting toothbrush include ① small brush head; ② The bristle hardness is moderate or soft; ③ The brush handle is easy to grasp; ④ Toothbrush suitable for different stages of children’s growth and development. Ordinary people who have mastered the correct brushing methods and developed good brushing habits can have greater choices according to their preferences. Specifically:

(1) ordinary people can choose a toothbrush with medium hair or soft hair and fully rounded bristle ends. Such a toothbrush not only ensures the cleaning power, but also softens the teeth and gums, which is not easy to cause damage in the process of brushing.

(2) for people who cannot master the correct brushing method, they should choose a more efficient and specially designed toothbrush, such as a toothbrush with crossed bristles or a suitable electric toothbrush.

(3) for people who cannot develop good brushing habits, they can use tools such as timer and plaque developer, or recommend using an electric toothbrush with intelligent guide.

(4) for people with rough tongue surface, a toothbrush with a tongue coating cleaner can help remove the tongue coating and reduce and prevent halitosis.
