There are a few articles that discuss the use of Botox to prevent the lip from raiding so high up which is giving you the gummy smile. Otherwise, a Le fort surgery can be done by an oral surgeon.
Unfortunately, when you loose a tooth you also loose gum and bone and the loss of those structures creates a food trap. Without seeing you it is hard to determine how to fix the problem. Maybe remake a crown?
Your crown fractured off the root. You need to make an appointment to have the roots removed.
Just looking at the radiograph provided. I would say that your third molar position is not favorable for extraction. It is a mesial horizontal impaction and is usually cut into multiple pieces for removal. As such the tooth could not be moved to an alternative postition because it needs to be removed in pieces.
Grafting is done with your tissue or alloderm (a dermal matrix). Your tissue invovles an additional site of surgery while alloderm does not. Generally speaking patients complain more about the grafted site then the site where the graft came from. Your tissue provides cells while the dermal maxtrix is acellular. Ultimately the thickness of the graft is greater with your tissue. Thicker tissue results is less recession and tends to stay around longer. Regardless you can not make a wrong decision just a more educated one.
