From 6 to 12 years old, the sixth-aged teeth of children in this stage are finally coming out. Sixth-aged teeth play a pivotal role in the establishment of our upper and lower teeth, and are responsible for the largest chewing function (as explained in the first article). How to judge and protect our sixth-aged teeth is particularly important at this stage of life. In addition, as the permanent teeth start to be replaced and the dental arch grows and develops, gaps will easily appear, causing food embedment and adjacent surface caries. Therefore, the responsibility of mothers is very important at this stage. The selection of toothbrush is the same as the selection principle of toothbrush for children aged 3-6 years old, mainly the toothbrush with small brush head, soft bristles, easy to grasp brush handle and suitable for children’s milk teeth at this stage of tooth replacement. Although they have already entered elementary school life, children are still full of childishness. Therefore, toothbrushes still highlight the fun, so that children feel their toothbrush and teeth as cute. Second, the amount and choice of toothpaste 1, the choice of toothpaste: it is still recommended to use the labeled fluoride toothpaste, safe and secure. Of course, you can still choose according to the taste of children. Or one of each flavor, depending on the mood to choose the flavor. 2, the amount of toothpaste: although this stage of the child can already completely vomit, but still use a pea-sized amount. Of course, mothers can also increase the amount of discretion, but the length of the toothpaste strip should not exceed 1cm Oh. Although children have already entered elementary school and started to write with a pen, their hand dexterity is slowly increasing. However, due to their young age, it is still difficult to master complex brushing techniques, so it is still recommended that parents teach their children the circular brushing method. However, there is a difference from the 3-6 years old. The toothbrush still uses a pencil grip, as shown below. This toothbrush is designed to make it easier for children to hold it with their thumbs and brush their teeth. Step 1: With the child’s mouth closed, the toothbrush enters the buccal space of the back teeth and the bristles lightly touch the gum area of the last six teeth of the lower jaw, where soft tartar can easily accumulate. The long-handled, small-headed bristle brush is more likely to enter deeper. In the second step, the mixed dentition stage, the newly erupted permanent teeth are larger than the baby teeth and there may be transient crowding. At this stage, parents should urge their children to brush more carefully. The third step, the sixth age, is still the most important. The action is still to do a short distance of 5 to 10 round trips from the upper jaw to the lower jaw, using 2 teeth as a unit. Since the sixth-aged teeth are located deep in the mouth, many children are prone to nausea, feel the brushing technique and overcome it slowly, never choke on it. In the fourth step, brush the upper jaw, still brushing from top to bottom. Step 5: When brushing the lower jaw, brush from the bottom up. Step 6: At this stage, six-year-old teeth have already erupted, and the occlusal surface of six-year-old teeth is large, with more and deeper gaps and cracks. Once decayed, the consequences are very serious, the previous article has already made it very clear. For children above 12 years old, I think you can fight like adults! Here’s a summary of a few issues that are easily blurred when brushing teeth. 1. How to keep the toothbrush? After brushing your teeth, the toothbrush will have oral food residue and bacteria adhering to it. Therefore, be sure to rinse it thoroughly with water, dry the bristles and place it in a ventilated place to avoid the growth of bacteria. 2.How often should I change my toothbrush? Generally speaking, you should change your toothbrush once every three months. Because at this time the bristles have a certain curvature, cleaning efficiency will decline, there is bacterial growth. However, I personally recommend changing it once a month, I always feel that there will be a lot of bacteria with three months, brainstorming, really can not stand. 3. How long should I brush my teeth? Clinical research says that people brush their teeth within the first 2 minutes with high efficiency, removing 80% of plaque, and after more than 2 minutes, the efficiency drops significantly. Therefore, it is recommended that you brush your teeth for at least 2 minutes. 4. How many times a day should I brush my teeth? After a few hours of brushing to remove plaque, plaque will reattach. Studies show that after 8 hours of brushing, plaque will return to the level before brushing. This means that you need to brush again when brushing for 8 hours. Therefore, it is recommended to brush at least twice a day, and it is even more important to brush at night before going to bed. If your child is not able to brush regularly or does not brush cleanly, mothers can only supervise their children until they develop good habits.
