most of macks milk teeth have come out already...but there's one(on the bottom one of the big pointy teeth) hasn't fallen out, but the new tooth has grown in around it and sorta pushed it outta the way. the puppy tooth is sort of a browny colour and it looks like the gums around it are a bit swollen. Also under his tongue on the side that the tooth is on, is sort of a darker colour. I'm not sure if this is due to the tooth, because hes got dark splotches all over his otherwise pink mouth.
What should I do about this tooth? I'm trying to get a picture of it but ill have to wait till hes sleeping!!
