Dental Treatment

Hi Everyone.  My son Joshua is needing Dental Treatment done so he can get on the kidney transplant list.  Joshuas kidneys failed 8 weeks ago and he has stage 5 renal failure.  Part of the transplant requirements are to have no dental issues.  We have ticked every other box, but cant proceed until this is done. He is an awesome 20 year old and we would appreciate any help possible. Thank you :)
