How long do braces hurt when you first get them on?

It depends on the person. I got braces and it started to hurt about 3 hours after getting them put on. The second day was way worse, with pain so bad, I needed Ibuprofen. I needed Ibuprofen for about 5 days before I could live with the soreness of the braces. As I said, it depends on the person and what they are getting fixed. I had an overbite and my teeth weren't lined up correctly, so there was a lot of moving in my mouth. Usually it takes around a week for you to fully adjust to the braces... It could also take more time. I hope this helped!
