Therefore, parents should always pay attention to the color of their children’s teeth, and if there are obvious black spots, they should promptly seek medical attention. Bleeding gums. It is normal for children without brushing habits to have small amounts of bleeding gums the first few times they brush their teeth. However, when a child has bleeding gums for a long time, parents should take the child to the clinic because the periodontal condition during childhood can affect the child’s future dental health. Sometimes, moderate periodontitis can even cause tooth loss in adolescent children, and even more so when the child is 30 years old and has a full mouth without teeth. Crowded teeth or jawbone dysplasia. Children who have finished replacing their baby teeth should be taken for orthodontic treatment if their teeth are misaligned, as early orthodontic treatment is the key for many patients with severe malocclusion, i.e., the proverbial “ground-bound” and “sky-bound” symptoms. In addition, the regular checkup of children’s teeth also has an important role to play. Second, children’s regular dental checkup Children regularly do dental health checkups, can achieve the purpose of early treatment of disease, disease prevention, especially oral health checkups have its importance. Because oral diseases are mostly chronic diseases, most of the early lack of conscious symptoms, easy to be ignored. Once the symptoms appear, such as pain. Swelling, etc., the disease is often more serious, hindering health, so it is necessary to achieve the purpose of early detection through regular oral health examination.

Regular dental checkups for children depend on both parents and society. Parents should bring their children to the hospital regularly for checkups, and the hospital can have a dental screening team that goes to kindergartens and schools to check children’s dental diseases regularly and tabulate the results of the screening as the basis for formulating dental disease prevention and treatment. With the continuous improvement of the oral health care system, the incidence of various dental diseases in childhood can certainly be controlled, which is of great importance to the health of children with vigorous growth and development. Third, the use of children’s toothbrush before use, soak 1-2 minutes with warm water, so that the bristles become soft; such as adding a small amount of salt, can play a sterilizing effect. When babies use toothbrush, the frequency should not be too fast; brush the upper row of teeth first, then brush the lower row of teeth, so as to avoid brushing to the gums. When brushing two rows of teeth, brush back and forth several times horizontally to remove the dirt on the surface of the teeth, and then brush up and down vertically to remove the residue in the crevices of the teeth. Brush lightly horizontally and slightly more vertically. After using the toothbrush, the mother helps the baby to rinse the inside of the bristles with water and shake off as much water as possible, and put the toothbrush head up in a mouthwash cup or put it in a ventilated place with sunlight to make it dry and sterilized. Toothbrush used for a period of time, the shell is still very new, but the accumulated dirt inside is difficult to clean, you can dip the toothbrush in white vinegar, after overnight, rinse it with water in the morning, the toothbrush will be like a new one. Usually replace the toothbrush once a month, the longest time should not exceed 3 months, or buy 2-3 toothbrushes at the same time to use in rotation. This allows the toothbrush to dry for a longer period of time while keeping the toothbrush bristles flexible. If the baby is boarding kindergarten, the mother or kindergarten should have the toothbrush thoroughly cleaned and disinfected once a week.
