My dog died during a dental. She was young (5 years old), healthy otherwise, and I'd done a slew of preop blood tests. (Not just the bmp usually ordered to check her kidneys). It was not her first dental. But, it was her first dental with a new vet. I'd actually switched vets because I was unhappy the the previous dental done by my old vets office.
I chose a vet who advertised dentals and up to date equipment and procedures. I did NOT go the least expensive route ( her dental was in the thousands).
Now, I should clarify...she was a greyhound and they have a genetic predisposition to horrible teeth. They also, because of their body mass index, don't process anesthesia the same way as other dogs. A good *specialty* vet should have known that.
I've since had dentals for my other greyhound. I was a crying snotty mess when I scheduled the appointment and explained to my new vet why I was so upset...She went through the entire procedure with me. She was also very up on current anesthesia literature and could give me details of anesthesia problems in her past surgeries. She was great, and I only use her services now.
The important thing to do is ask questions. Lots of questions. And research ahead of time. Know what answers you want to hear.
My dog did not die during the procedure..she died in recovery. In my heart I know that she was given too much anesthesia. I also believe she was under anesthesia too long..( when I got the call, it was after lunch and she was supposed to have her procedure first thing in the AM)..I have suspicions that she was left under anesthesia while the vet attended to other pets.
I'm sorry this is so long. But I can't tell you enough how horrible it is to lose a pet this way...especially when you think you've done every thing right.
