If you’re someone who thinks that a patent airway is going to be a problem, then you need to go to a practice that has privileges at a hospital with a pediatric sedation unit. It’s the anesthesiologist, not the dentist, who is responsible for the airway. Often with a nasal intubation but not always.
The person up thread, who quoted the dentist saying I just look at the teeth and jaw was correct. The question to ask is who’s your anesthesia practice?
