cleaning the mouth and protecting teeth are inseparable from the toothbrush. Brushing with an unsuitable toothbrush is prone to gum damage, bleeding and other phenomena. Dental care requires the use of a toothbrush. The quality of the toothbrush directly affects the health of teeth and gums. However, how to choose a suitable toothbrush? The following three standards can be used as a reference for your purchase. One of the
standards: the size of the brush head should vary from person to person
1. When buying a toothbrush, first look at the size of the brush head. The doctor said, “the brush head is usually a little smaller to ensure that it can rotate flexibly in the mouth. Children’s mouth is small, so the brush head needs to be smaller. In general, the size of the brush head should be determined according to each person’s situation, and factors such as oral size, mouth opening degree and personal habits need to be comprehensively considered. There is no uniform standard. ” The American Dental Association recommends that the adult toothbrush should be: the brush head is about 2.54-3.18 cm long and 0.79-0.95 cm wide; 2-4 rows of bristles, 5-12 bundles in each row. However, adults can also choose a children’s toothbrush with a brush head 2.3 cm long and 0.8 cm wide.
2. It depends on the soft and hard bristles. The bristles should be moderately soft or slightly soft. However, it should be noted that too soft hair is easy to brush unclean. The previous bristles were made of bristles, which were very hard and easy to hurt teeth and gums. Now they have been basically eliminated; At present, the bristles are mostly made of nylon silk. Specifically, it can be divided into two types – ordinary silk and DuPont silk. DuPont silk has good elasticity and is not easy to fall.
3. Sanding is also important. If the bristles are not smoothly treated after cutting, they are easy to be hurt because they are too sharp. The sharpened toothbrush with rounded brush tip can prevent this kind of injury and has a stronger protective effect on gums.
4. Change the toothbrush every three months. The doctor reminded everyone that the toothbrush had better be replaced every three months. If it is used for too long, bacteria will accumulate in the bristles, which is unfavorable to oral health. People who use DuPont bristles should not change their toothbrush because the bristles are not inverted.
5. Select ordinary straight handle toothbrush. Whether the brush head is square or diamond shaped, whether the upper edge of the bristles is flush or wavy, and whether the brush handle is curved or straight have no effect on the brushing effect. Brush your teeth with the most common straight handle toothbrush.
standard 2: electric toothbrush is suitable for special people
electric toothbrush has been gradually favored by people because of its convenience and labor-saving characteristics since it landed in the Chinese market.
electric toothbrush is divided into two types, namely ordinary electric toothbrush and sonic vibration toothbrush. Ordinary electric toothbrush is recommended for the elderly, children or people with inconvenient physical activities. However, the efficacy of this kind of toothbrush should not be too superstitious. As long as the brushing method is correct, the manual toothbrush is as easy to use as the ordinary electric toothbrush.
relatively speaking, the sound wave vibrating toothbrush has a stronger health care effect. It can flush out the residual food between the teeth through the sound wave. This effect is massage type, cyclone type and precursor type… In the face of a wide range of toothbrushes on the supermarket shelves, many people have this question: “the propaganda of each toothbrush says that its efficacy is unique. What kind of toothbrush is the most suitable for you?” In this regard, the stomatologist said: the toothbrush with small brush head, moderate soft and hard bristles and frosted treatment has the best health care effect.
standard 3: interdental brush
teeth have five surfaces. The outer side, inner side and bottom surfaces are easier to brush, but the two surfaces opposite to the adjacent teeth are difficult to brush. Some auxiliary tools – interdental brush or floss are needed. If the gap between teeth is large, it can be brushed between teeth.
this is a small brush similar to bottle brush. The brush head is wound with fine nylon wire and stainless steel wire. It can extend into the teeth to remove residual food. If the gums need to be brushed in, it is not suitable to use hard dental floss. If the gums need to be brushed in, it will damage the gums.
