I guess I was so relieved that I forgot to post about our vet appointment today! Her vet said that it looked like the tooth had snapped off, that there weren't any roots on the tooth (which I brought with me to show him), but he also didn't see anything left in her mouth. He said it's possible the root part fell out after the tooth, and it's also possible that a little bit could be left in her mouth that we just can't see right now. He just told me to watch that area for any swelling and inflammation, but that he thought it would be just fine. Yay!!!! I'm so relieved! I was really getting worried that something else was going on. He said maybe she ran into something that I didn't notice or something....I have no idea how it happened.
(Also, I asked him about scraping her teeth myself, which I just did for the 2nd time 2 or 3 wks ago, and he said her teeth and gums look amazing! He said that when she starts getting older, that she may need a professional cleaning to get anything that starts getting built up under the gum line, but that I'm doing a great job taking care of her teeth, and that scaling them once per year won't hurt them at all....where people get in trouble is when they're doing it fairly often. He said to keep up the good work and to also keep on brushing! I know a lot of people on YT are against it, but I've had 3 vets now tell me it was okay to do it myself. Honestly, I'm just trying to balance out the negatives with the positives, and I think for us this makes more sense than sedating them...for now. I do know that in a few years, they'll need that professional cleaning anyway, but until then, I'm going to do what I can to keep theirs little mouths in as good a shape as I can.)
