I have a 6 pound chihuahua/Yorkie mix.. Yes a Chorkie She is only 3 years old and her teeth look terrible. The vet recommended a cleaning within the next year, but today I was examining her teeth and found that the front 2 bottom teeth on the bottom are very loose. I'm afraid this could be a sign of gum disease. My question is, should I take her back to the vet, we just went a couple weeks ago? And, I am very wary of teeth cleaning because the vet puts them to sleep, so from everyone's experience, how safe is this procedure? Thanks so much for any info and advice!!
