What you said is actually hard to understand. Don't worry, describe it clearly so that we can answer you.

Do you want to say: I want to correct the front teeth because they are crowded, but I went to the hospital and asked the doctor. The doctor said that two teeth need to be pulled out to make room for correction, and the doctor also said that the dentition will become loose after pulling out (in fact, you use the word loose because my head is big, because there are two meanings in it, which means that the dentition looks sparse or that the other teeth will become loose after pulling out? ), now you are worried about whether you should get out, whether you should take the risk or how to avoid it, right?

Let's talk about tooth extraction first. As for why it should be pulled out, it is to make room for your dentition. As for the loose problem you are most worried about, because you don't understand your problem, it is not easy to jump to conclusions, but generally speaking, there is no need to worry. If the doctor said that, it's best not to ask him for orthodontics (because he doesn't even have the confidence and skills to do orthodontics well. I haven't heard of any doctor who is worried about loose teeth after tooth extraction! ), in fact, your worry is unnecessary. After the gap is cleared, there may still be residual gaps. As for how to close the residual gap, everyone who has studied orthodontics knows that it is necessary to rebuild the occlusion in the later stage (ensuring a good occlusion is the place to embody the technology). Unless it is extremely special, such as people with poor oral hygiene will worry about loosening, but people with poor oral hygiene will definitely not do it for him. What you are worried about is unnecessary.

Your age correction is very good and the effect will be very good. Don't worry. Finally, find a better orthodontist.
