Mine went under twice for pulling baby teeth because the first vet chose not to pull one and missed the other entirely. The next vet almost exactly a month later (took me that long to settle on a new vet and wait out the snowfall
) had to pull those two plus 2 adult ones (one was an incisor). The one the first vet chose to leave behind almost immediately had lint and fabric strings wrapped around it from her chews. I was never able to remove all of it with my nails and she'd bleed and it really stunk and she had inflamed gums. Since it was so diseased, it took the adult tooth down which was next to it. The baby tooth that was in the back side of her mouth sandwiched an adult tooth with her canine. It was pushing the canine up against her other teeth. Rather than risk it never moving away from the canine on its own, we opted to pull that one out also so that we wouldn't be putting her through this for a third time!
My girl was around 5.5 lbs when she got hers done at 10 and 11 months old. The sooner you get it done the better! Good luck!
Maybe your original vet did have all the baby teeth present at the time pulled and it just grew in later than the rest of them? I'm also thinking it might be possible to wiggle the "loose" one out or wait another two weeks for it to be removed by the pro's
. I couldn't help myself when I wiggled some of my girl's loose ones out prior to any dental work because a couple of them came out easily.
