I know you already made the appointment and this advice is likely too late, but I would give her another month or so if she doesn't have any other problems yet (eg, double teeth, crooked canines). I went through this with Rocco and his canines seemed firmly planted, but I 'helped' him loosen them by holding bully sticks and Himalayn chews while he chewed on them. This helped him to really bear down HARD while chewing. I did this for about 2-3 weeks a couple of times a day, then the canines finally came loose and all 4 fell out within about 5 days! That said, please do what you and your vet feel is best for Claire. I just wanted to let you know that it can happen fairly quickly, and since she's so young hers may do the same. Best wishes either way
