Hi, it depends on the dentist, find out from them if it will be hospital or just dentist job by, usually hospital will be for problem ones. Mine were taken out at the surgery. As for hypos, no, they don't check in the dentist. I had a tooth out yesterday and to avoid hypo, I just ate a little more and dropped my insulin a couple of units, I figured a short term 'high' a safer option. My main concern was what I could eat afterwards to be honest but luckily this one didn't hurt afterwards at all. If they are done at the hospital, which it seems likely, then yes, they will monitor your blood there. Hope tis helps!
