Getting Braces with Multiple Dental Issues

Hello everyone, I want to hear about experiences and advice from those who have had braces while dealing with significant dental issues, like cavities, tooth decay, or fractures, especially if most or all of your molars were affected. I’m getting braces but I'm worried about how these dental issues might affect the process. Did anyone else have similar dental problems when you got your braces?, How did your orthodontist handle the issues with decayed or broken molars?, how did braces impact your existing dental problems, and did it affect the healing or treatment process?
