Hi welcome to PT. Sorry but I have nothing much to offer a I have never cleaned by cats teeth. Had I known that this was possible to do when I got mine as kittens I would have started doing it then. On occasions my vet had removed plaque/tartar build up with his finger nail. He just holds my cat, opens her mouth and kind of digs his nail in at the top where the tooth meets the gum and yanks it off. She doesn't seem to mind. It all comes off in one go!
