Hole in my tooth! Edit

I have been like 5 times this month and have more appointments coming up. I just had cavities fixed and they said they didn’t see one but under my retainer hurts like a cavity and there is a tiny hole in the top of the tooth I touched it and it shot pain down the tooth . She said it probably my gums but should I go back to make sure? Or just wait it out? I am having my wisdom teeth and my second round of braces (Invisalign) next month, and thousands upon thousands have been put into my mouth to have nice teeth so I don’t want a tooth rotting or something and ruining them (don’t know if that’s what actually happens but they obviously fix them for a reason right?) and I don’t want more pain then my wisdom teeth and braces . But She said she doesn’t think there is one. What should I do?
