Today, the author, Fat Peach, confided her child’s dental experience: her child went to have a cavity repair, and because the cavity was up to 8 teeth, and she was worried that she might need root canal treatment (which is super painful), she chose comfort treatment and used gas anesthesia. In the end, I reflected that the main reason was that I was not aware of the problem, and I always thought that it didn’t matter if the decayed milk teeth were decayed, because the permanent teeth would be replaced anyway. As a result, the more you delay, the more serious it becomes. In fact, the most decay-prone part of the child’s teeth is the big teeth, which will not be replaced until the age of 12. These long years are enough to damage the pulp and nerve of the baby’s teeth. If the cavity hurts the nerve, the permanent teeth will be very much affected and root canal treatment will be required. Therefore, the first step to prevent cavities is to take your baby to do guttering. I. What is gutter closure? It is to seal the grooves on the surface of the big teeth with a material, like closing the tile gap, so that the bacteria can’t go in and there is no space for the Harker and Dicker bacteria to get in. The teeth will be much safer and less likely to be decayed. Second, how many years old with children closed ah? The baby teeth can be closed when they are 2.5 years old. Is the child cooperative? This depends on whether the child is used to visit the dentist regularly since childhood. Children who have been receiving regular dental management since the age of 1 will have no difficulty. Children who have never been to the dentist before may not be cooperative and will need some time to get used to it. Third, the teeth are closed, you can rest assured! It is not true that the sealant is not a caries vaccine, you will get caries if you don’t brush your teeth properly, and you need to brush your teeth carefully, you can’t be lazy. The gaps on the tiles that were sealed will be cracked again and some of the sealing materials will be lost, the same reason, the teeth will affect the sealing materials when eating, so you need to go to the dentist regularly to check, no problem, of course, it is good to find part of the off need to close again in time. Well, the baby has been regularly scaled, fluoride coated, sealed, brushed and flossed every day, and has developed a good habit. Very good, just keep going. The child is growing up day by day, six years old, permanent teeth should grow out, permanent teeth also need to be closed. At the age of six, the first molar is closed, from 10 to 12 years old, the second molar is closed. At this time, the permanent teeth have just grown out, the calcification is not very mature, is an important time to close. Some people say, “Oh no, I missed it, is it still possible to close them?” The answer is, it can be closed, let the doctor check it, if the sulcus is deep, it can be done. But if the caries is already there, it is not a problem that can be solved by sealing, it needs to be treated by restoration. Prevention is always the right choice, don’t let your child’s teeth rot because of parents’ neglect! Healthy teeth mother’s pride!
