I have a friend who is 2 1 year old and is doing orthodontics. The doctor said that the best time for orthodontics is 12 and 13, but 2 1 is not too old, but her gums are normal. The doctor also said that if the gums are deformed, the sooner the better. If the teeth are deformed, it's no big deal. Maybe the effect is not perfect, and the older you get, the longer it takes to correct it. My friend 1.5 to 2 years. Moreover, if your teeth are big and protruding, maybe the doctor will ask you to pull out a few teeth first, and then wear the appliance for 3-5 days, so your teeth will be sore and you can only eat porridge, and then go to the clinic once a month, and there will be 3-5 days after each visit. Imported from Japan, Germany and the United States are more exquisite, shiny and expensive than domestic ones, but they are more comfortable to wear in the mouth. Wearing braces will also wear out the mouth at the beginning, and even cause ulcers, but it will get better after a while. These are also individual differences, and my friend is fine. The doctor will tell you when you get them. It's best to go to a special stomatological hospital, because my friend has done it before.

You can go to the hospital for a registration check and see what the doctor says. Check it first. You don't need to do it at once. If you want to do it, you should take pictures first. That's all I know. I hope I can help you.
