My husband had to have all his teeth removed in Feb. before he could start treatment. He is scheduled to see the Oral Surgeon the last of Nov to make sure his gums have healed enough to be fitted for dentures. My h. was also a smoker he used a new drug called Chantix this is a perscription drug but for him it worked. Our son tried it and it didn't work for him but he didn't have the urgency to stop like his father. Stay in touch and hope this helps.
