hello, i have periodontal disease an my gums are receding badly,i cant hant have a graft because i have been told their is not enough tissue there to do it,is it possible to still have grafting because i dont want to lose my teeth which are fine,i did look at a site somewhere,that they can do grafting with another animals tissue ,instead of taking it from the roof of the mouth,also i do smoke a lot,also their is a company with a product called qsiant i was wondering does that work? wouldnt it be ideal if the tissue came from my own mouth? i don’t really know how it all works, a little explaining would be great before i head into getting this problem fixed. thanks for your time
