I am just being curious here Derek. Was Kisa under sedation or under anesthesia? Sedation involves an injection and is an awake but a "don't give a ****" condition, like a human being on an opiate. Anesthesia is a "fully under" condition brought on by gas being given into the lungs through a facial mask or intubation.
The reason I ask is because a dental cleaning performed under only sedation (or not even under sedation) is not a dental procedure. With a dental procedure, a vet tech or vet scrapes tartar off all the tooth surfaces and probes the tooth surfaces and the pockets around the teeth for dental disease. And sometimes extractions are needed (and it normally is the vets who do those).
With sedation only, that is usually called something like a "dental scraping" or a "non-anesthesia dental," and there are even people without veterinary training who will do those procedures. Those procedures are, IMHO, not only worthless but also dangerous because you can miss information about serious dental disease that you cat has. And diabetic cats, with the sugar in their systems that can decay teeth, do need frequent, quality dental care.
