I just noticed this last night, and is this common? It looks like his left canine is wearing a hole in his lower lip 
Here is the best picture of it, among a few others:

It has that yellow/orange crusty stuff in it sometimes, and it's red around the hole. Do we need to see a dentist? I hate canker sores, so I can't imagine how needling this must be for him.
