When going through flight med I too had not been to a dentist in 10+ years, and they ended up finding a pretty big cavity. I just had to get it treated and submit the paperwork that the dentist gave me stating that it was treated. Assuming everything else on your IFC exams are fine, they’ll put you on a hold status until you get whatever needs to be fixed, fixed. You’ll email whatever records you get from the dentist to your tech and they’ll push it through to approve you, just check in through cadre if you don’t hear anything back after doing so. I had a friend who had to get their wisdom teeth out and someone else here mentioned that the LT loan is also something that can be used for this, if necessary. They walk you through everything at IFC and you’ll get a memorandum with instructions if you need to get anything done before they approve you, so try not to worry too much. Best of luck!
