What is happening to the inside of my teeth?

[Braces2017]

I have been doing everything the dentist said and the orthodontist. I have flossed brushed everywhere and flossed. I have now noticed my inside teeth inside have gone brown! Why?? I have been using clinpro tooth creme that the dentist gave me and the dentist said there fluoride toothpaste would not make my teeth brown but I don't know what else could? I haven't changed my diet. Anyone had this happen to them? I'm so worried and the dentist said no rush to book me in. Just to stop using the paste for a week!

I don't have any experience with the issue, sorry, and wanted to wish you good luck. Perhaps it can be reversed just as quickly as it began. I have to think it's the toothpaste from what you have said. If not the fluoride, then something else in the mixture.

Cetyl Pyridinium Chloride (in some mouthwash) can cause brown staining. If this is the case, it can be polished off.

I had a bunch of staining suddenly appear between by teeth (where the floss touches) and my hygienist buffed it off.
