1. The dentist with braces didn't treat your pulp thoroughly.

2. All other teeth are decayed.

I suggest you go to the dentist for a careful examination and see what the situation is. In the first case, the dental pulp (tooth nerve) needs to be reprocessed, and the braces may need to be removed.

In the second case, which tooth is broken is treated.

I wish your teeth a speedy recovery!
