According to experts, the U-shaped toothbrush, also known as the lazy toothbrush, has a U-shaped brush head, which is similar to the arrangement of teeth in the mouth. Many U-shaped children's toothbrushes are cute and come with lights, nursery rhymes, etc., which can make children better accept brushing their teeth. The U-shaped children's toothbrush is conducive to cultivate children's interest in brushing teeth, and then slowly transition to an ordinary toothbrush, but it is not recommended to use the U-shaped toothbrush for a long time.
Medical information network learned that each child's dental arch shape is different, but the shape of the brush head of the U-shaped toothbrush is fixed, which means that it is difficult for the U-shaped toothbrush to fully fit all tooth surfaces at the same time, and it is easy to have a cleaning blind area when brushing teeth with it. In addition, the bristles of the U-shaped toothbrush are mostly made of silica gel, which is soft, and the cleaning force is not enough, so it is difficult to completely remove dental plaque. In addition, due to the thick silica gel bristles, it is difficult to clean each tooth gap and gingival sulcus, which will also lead to unclean brushing. Long term use of a U-shaped toothbrush is at risk of dental caries.
According to experts, parents should brush their children's teeth from the moment their children sprout their first tooth. In infancy, parents can dip gauze in light salt water or use finger toothbrush to help their baby clean his mouth. After the age of 2, you can start using an ordinary toothbrush. When choosing an ordinary toothbrush for your child, you should pay attention to the following points:
The size of the brush head should be moderate. Children of different ages have different oral sizes. Only a toothbrush with appropriate brush head can better rotate and clean each tooth. It is best to choose the product marked "children's toothbrush" and choose the brush head according to age to avoid being too large or too small. Parents can take their children's upper anterior teeth as a reference. It is generally recommended that the length of the brush head of children's toothbrush is about the width of two front teeth, and the width and height of the brush head is about the width and height of one front tooth.
The bristles should be soft and hard. According to the current national standard of children's toothbrush, the bristles of children's toothbrush should be soft, and the diameter of bristles should be Less than or equal to 0.18 mm. Finer bristles can go deep into the teeth and clean more cleanly. But it should be noted that the finer the bristles, the better. Some super fine bristle toothbrushes will greatly reduce the cleaning effect due to insufficient hardness and weak cleaning force. Too hard bristles may damage the child's gums, leading to gum recession and tooth wear. When parents choose, they can take the toothbrush and try it on the back of their hands. If the bristles are not seriously deformed and there is no obvious tingling on their hands, it means that it is appropriate to be soft and hard. In addition, the top of the bristles should be rounded and smooth, which can not only effectively clean the dental plaque, but also avoid damaging the gums.
The length of the handle is moderate, and preschool children are still difficult to master and complete fine and complex brushing movements, so they need parents to help them brush their teeth. At this time, the children's toothbrush can choose a thin and long toothbrush handle to facilitate the operation of parents. Children over 6 years old can start brushing their teeth by themselves. They should choose a short and thick handle to facilitate children's grasp.
Many parents are obsessed with whether electric toothbrush is better or ordinary toothbrush? In fact, both electric toothbrush and ordinary toothbrush can effectively clean teeth as long as the brushing method is correct. Children's correct brushing method can refer to circular arc brushing method.
