X-rays should be done before a dental, to make sure there is nothing lurking below the gum line that cannot be seen by visual inspection alone. Had that happen with Neko. Even the dental specialist needed the x-rays to see what needed fixing. Clindamycin should kill any infection, though it does a number on your GI system (speaking from personal experience

) and you usually need to add a probiotic. That might have been why he's hadn't been feeling quite himself.
I wasn't commenting on the testing for following TR, but rather the timing of increases/unearned decreases. Zeke is now considered a long term diabetic. With TR, that means decreases below 40, or one week in greens, or 3 days with numbers from 40-50 if he's not holding reductions well.
