19 to wear braces. . . . It's not too late to 18, but it will be better and faster to make corrections when you 12 to 13. The braces I wear are imported, and the domestic effect is not as good as imported ones. Because I'm old. My classmates recommended me to go. I don't feel anything loose. The purpose of wearing braces is to straighten teeth neatly and beautifully. It is impossible for teeth to fall off easily when they are old. There will really be some oral ulcers when I first wear braces, because it will be fine after all. I suggest you go to a dental clinic with a good reputation, because the examination and registration fees in big hospitals are much more expensive than those in dental clinics. I used to be in a big hospital here, and I had to pay a registration fee for every check-up, so I would go to the dental clinic my classmate used to do, and the price was better than that of the big hospital. In fact, my suggestion is that if your teeth don't need to be corrected, you'd better not wear them, because when I wear them once a month, that tooth will hurt for a few days. At first, my mouth was a little worn out, but I got through it. Sometimes you accidentally loosen your braces by eating hard things. Sometimes I feel that I spend money just to find a punishment. But if you're really not afraid, put it on. I can take off my braces in two months. In fact, I am very happy to see my teeth become neat. Ha ha.
