brushing is something we do every day. Some women who love hygiene brush their teeth three times a day. Are we right every day? How to brush your teeth correctly? Next, let’s take a look at the related knowledge about brushing teeth with you.
how to brush your teeth correctly?
it is not suitable to wet the toothbrush before brushing, because it may lead to unclean brushing.
when most people brush their teeth, they habitually wet their toothbrush before squeezing toothpaste. But in fact, brushing your teeth can’t be like this.
if the toothbrush is wet, after squeezing toothpaste, it will easily frother. There is too much foam in the mouth. People will feel that they have been brushing for a long time and think it can be over. At this time, the teeth are not really cleaned.
toothpaste is not used to clean the teeth with foam, but depends on the cleaning elements inside and the friction between the toothbrush and the teeth. The finer the friction, the longer the time, the cleaner the brush.
, the right way is to brush the toothbrush without dipping water, squeeze toothpaste slowly, and gradually produce some subtle bubbles.
correct brushing method recommendation:
partition brushing, first of all, according to the whole teeth up and down, left and right, divided into several small areas (each area contains about 2-3 teeth); Brush in order, in a certain order, such as first up and then down, first left and then right, first outside and then inside, so as to avoid omission; Brush on three sides, including buccal, palatal and occlusal surfaces (the side where the teeth chew food); Repeated scrubbing is required in each community for 3-4 times.
the side with bristles was first placed on the side of the buccal and palatal side of the teeth to be brushed, the bristles were parallel to the long axis of the teeth, the tip of the bristles was toward the gum, close to the gum and the tooth surface, and then the toothbrush was rotated about 45 o, along the gap between the teeth to the occlusal surface (upper teeth from top to bottom, the upper teeth from top to bottom), The lower teeth (from bottom to top), with pick brush action, brush dirt; If the teeth are square or wide, the above action can be used. When the teeth are pointed or narrow, the tip of the toothbrush is contacted with the surface of the tongue and moves in an arc from the gingival margin to the incisal margin; The toothbrush bristles are pressed tightly on the occlusal surface and pulled forward and backward.
teach you to choose a toothbrush with good health effect
when you buy a toothbrush, you should first see the size of the brush head. Generally, the brush head should be a little smaller to ensure that it can rotate flexibly in the mouth. Children with small mouth need smaller brush head. In general, the size of the brush head should be determined according to the individual’s situation, and the oral size, mouth opening degree and personal habits should be taken into account. There is no uniform standard& rdquo; American Dental Association suggests that adult toothbrush should be: brush head length about 2.54-3.18 cm, width about 0.79-0.95 cm; There are 2-4 rows of bristles, 5-12 bundles in each row. However, adults can also choose a 2.3cm long and 0.8cm wide children’s toothbrush.
secondly, it depends on the soft and hard bristles. Brush hair to choose moderate soft and hard, or slightly soft. But pay attention, too soft hair easy to brush not clean. In the past, bristles were made of bristles, which were very hard and easy to damage teeth and gums, so they have been basically eliminated; At present, the bristles are mostly made of nylon wire. Specifically, it can be divided into two kinds — ordinary silk and DuPont silk. DuPont has good elasticity and is not easy to fall down.
third, sanding is also important. If the bristles are not smoothed after cutting, they are easy to be hurt because they are too sharp. The toothbrush with rounded bristle tip can prevent this kind of injury and has stronger protective effect on gingiva.
at the same time, doctors remind you that it is best to change the toothbrush every three months. It is harmful to oral health if it is used for a long time. People who use DuPont bristles should not change their toothbrush because the bristles do not fall down.
in addition, the brush head is square or diamond shaped, the upper edge of the brush is flush or wavy, the handle is curved or straight, which has no effect on the brushing effect. Brush your teeth with the most common straight handle toothbrush.
