I have a 20 month old yorkie and just had her teeth removed about a month ago. Her baby teeth were growing on the gum side of her mouth. My vet had told me to have them removed when she was spayed but due to funds kept putting it off. In the end I wish that I had the baby teeth removed and spayed much much earlier. She ended up having to have a deep cleaning due to the amount of build-up that had accumilated over the year. I definately recommend your baby have them removed soon, before it becomes a problem periodontically. Bunjee will be much happier and healthier. It can also be a bigger problem when the teeth are growing on the palate side and could affect the development and alignment of his teeth. Hope this helps!!
