Chase had a carnassial tooth extracted but to my knowledge, there was no bone grafting. I'd have to look for Chase's dental work receipt to make sure there was no grafting done but it doesn't strike a familiar note. I myself had a bone graft after an extraction of a molar, however. But they said that was because I had to get an implant in that location and supposedly I needed more bone there. Sadly, no more raw marrow bones for me either.
