I got a good look at Pippa's adult teeth last night and I realized that her adult canine (upper right) came in just in front of her puppy tooth...but the deciduous tooth never fell out! How long do I wait to see if she drops it? How much should I expect to spend if we need to get it extracted? She is seven months old, now, and all of her other adult teeth appear to have come in correctly. The new canine isn't digging into the bottom gum and appears to be correctly placed.
