They wouldn't approve me for mutual aggravatiopn of DM/perio because the c&p dentist claimed that my perio wasn't severe enough. The first question she asked me was whether I was on insulin (no), tthen whether I had active severe infections in my mouth (mostly just inflammation, no pus). If you are on insulin and have active infection, you should be approved. She also said that if I were using a less busy clinic they might treat me at my level of severity. If you do have active infection, your VA primary care doc should be able to refer you to dental for emergency care, since if the infection is that bad, it would definitely aggrave your blood sugar level. Welcome home and good luck.
