“I brush my teeth properly every day, why do I still have all kinds of problems?” When a dentist is asked this question, it is tempting to ask the patient in return, “Do you know anything about teeth? What do you know about dental care?” Don’t be unable to answer anything. First, let’s learn about our teeth. Teeth develop in our bones after we are born, starting with baby milk teeth at about 0.5 years of age and reaching a full set of 20 milk teeth by about 2.5 years of age. The baby teeth are eventually replaced by permanent teeth, and the first set of permanent teeth, commonly known as “six-year-old teeth”, appear around the age of 6. After that, the permanent teeth will be replaced one after another, and all the regular permanent teeth will come in around 13 years old, 28 in total. These are the teeth that we will use for the rest of our lives, eating and looking good all depend on them, and dental care should naturally follow. By the way, around the age of 20 is the time we grow wisdom, is also the last set of permanent teeth, so called “wisdom teeth”. But “wisdom teeth” not everyone grows, each person grows 0-4 “wisdom teeth” are possible. Even if you have “wisdom teeth”, they rarely grow straight. On the one hand, crooked “wisdom teeth” will damage the front teeth, on the other hand, it is not easy to clean, easy to hide dirt, causing caries and inflammation, so dentists usually recommend the timely extraction of “wisdom teeth”. After understanding our teeth, it is time for dental care. Brush your teeth? Yes, but do you really know how to brush your teeth? It’s not just a matter of squeezing some toothpaste onto your toothbrush and brushing. So how do you do it? First of all, you have to brush your teeth with the right attitude, remembering that a lifetime of teeth needs to be treated with sincerity. A good set of teeth is largely determined by the moment-by-moment maintenance of brushing every day. The goal of brushing is to maintain the cleanliness of every part of your teeth, without missing anything. Where it is missed, there is a breakthrough for bacteria and microorganisms to attack your teeth. How can you brush your teeth without missing any spots? Dentists recommend the internationally accepted bass brushing method: choose a soft-bristled toothbrush, no toothpaste required. When brushing the front and back of the teeth, turn the bristles of the toothbrush about 45° towards the gums, press the gum-tooth junction area, make the bristles cross the gums and the tooth surface of the neck of the teeth, and lightly make the bristles tremble horizontally in the original position for a short distance 10 times in the front and back direction. After 10 horizontal tremors, move the toothbrush to the next set of teeth and operate as before; when brushing the chewing surface of the back teeth, brush the toothbrush back and forth against the tooth surface; when brushing the inside of the front teeth, put the toothbrush up and brush it up and down against the inside of the front teeth. Brush your teeth for at least 3 minutes each time, once in the morning and once in the evening. If there is food embedment, use dental floss correctly to clean up. For special periods such as mouth ulcers and inflammation of wisdom teeth, it is recommended to use mouthwash in conjunction. These are the necessary and effective dental care that we carry out daily! However, many people still have doubts because they are guided by professional dentists to brush their teeth and brush in a completely correct way, but still have dental problems, such as tooth decay (i.e. rotten teeth), tartar and tartar, red and swollen gums, bleeding teeth from brushing, loose teeth …… that must be too many dead ends of the teeth that cannot be reached by the correct brushing method, which is hard to reach. The most common cases of teeth with many dead corners are when the teeth are not aligned, inside out and outside in. When teeth are misaligned and lined up together, many tooth surfaces are covered and cannot be cleaned, and tartar appears, which in turn mineralizes to form tartar, providing a protective shell for bacterial microorganisms. Under the cover of the protective shell, the bacteria and microorganisms further erode the teeth and bones, gradually causing a series of dental problems such as tooth decay, red and swollen gums, bleeding, and loose teeth. As the saying goes, “cure the disease to the root”, now we know where the “root” is, how to treat it naturally is clear – align the teeth – orthodontic treatment, commonly known as “orthodontic treatment”. -Orthodontic treatment, commonly known as “orthodontic”. This is one of the major reasons why “orthodontics” has become popular among children, teenagers and adults in recent years. Another important reason is that orthodontic treatment can improve facial aesthetics and eliminate the psychological barriers caused by malocclusion. Therefore, dental problems should not be underestimated, and dental care is no longer a personal matter, you need professional guidance. Professional dentists recommend a lifelong dental care process: 1, for children and adolescents, even infants and young children, led by parents to the clinic, please professional dentists throughout the guidance, dental care; 2, for adults, more or less still appear dental problems, early consultation, do a comprehensive dental examination, a clear understanding of their dental problems, and then the right treatment, to extend the life of teeth, improve the quality of life; 3, for uneven teeth, which affects the health of the teeth. 3, for patients with uneven teeth, affecting health and aesthetics, do not miss the best time for “orthodontics” – when the teeth have just been replaced (around 12-14 years old for boys, 11-13 years old for girls), individual cases like backbite (commonly known as When you have just finished replacing your teeth (around 12-14 years old for boys and 11-13 years old for girls), you should consult with your orthodontist as soon as you notice any backbite (commonly known as “geodontia”), crooked chin, or small chin.
