1, extraction will make other teeth loose Every tooth has its own periodontal tissue wrapped, periodontal tissue includes gums, alveolar bone, periodontal membrane, etc. After extraction, the alveolar socket will be filled with blood, mechanized, and then become bone. It takes three months. The wound grows flat. That is to say, one tooth, one alveolar socket. One carrot and one pit. There is no effect on other teeth after extraction, and the teeth will not loosen. If there is, there is a chance that the adjacent teeth will tilt towards the extraction and the opposing teeth will elongate. This is because the balance between the upper and lower, left and right is broken. 2.Cleaning produces large gaps Generally, when brushing and bleeding, the doctor will ask the patient to clean the teeth, but some patients say that cleaning will produce large gaps, and what was not there, will be there after cleaning. This is a big misconception. The anatomy of a tooth is crown, neck and root. There is a gap between the tooth and the tooth itself when there is normal contact, and there is a gum papilla covering it when it is normal. When there is tartar accumulation, it will be pressed and recede, and the original gap will be revealed when the tartar is removed by tooth cleaning, it is not the gap created by tooth cleaning, it is the original gap. 3.It doesn’t matter if the milk teeth are decayed. The milk teeth grow 20 pieces from two and a half years old and start to replace at the age of 6 to 12 years old, the time is up to 10 years. During this period, the chewing, nutritional intake, jaw bone development, the replacement channel of permanent teeth, and the cultivation of aesthetic —– mental health are all very important, so it is not dispensable, so when it is decayed, we should find a dentist to take a good look. You can’t just ignore it because it needs to be replaced.
