OMG I recently saw a horror story on Facebook about one of these dentals.
I spoke in the past with the vet dentist I have used on occasion and she said these are bad, bad, BAD!!
First of all, most dental issues are under the gum line.....a really GOOD dental includes dental xrays. I have been told that vets really should not do dentals without doing dental xrays....BUT, it is still safer to do that than to do an anesthesia free dental. I have had pups lose teeth due to stuff seen under the gum line where their teeth didn't look so bad to me. I saw the xrays and knew it was necessary.
I am going to search on FB to see if I can find that story about that poor dog. It was horrifying.
I HATE that people are pushing these dentals....they do this by using the fears of people of anesthesia when in fact anesthesia done properly is perfectly safe.
