What about smoking after a full all teeth extraction and dentures ? i know its a horrible question but i wonder how that changes things or what happen

Smoking: It will kill you from COPD or CA lung and increase your risk for heart attack, stroke and sudden death and make your teeth fall out. Whoops what has already happened.

As I'm Sure: Your dentist told you, smoking can cause bleeding so no smoking at all for the first day. Then try to keep it to a minimum. Avoid "sucking" on the cigarette, as you might dislodge the clot and cause more bleeding. There are few things you can do which would be as good for your future health as quitting.

Smoking: Will interfere with healing, prolonging healing time, increasing risk of infection and dry socket, and will immediately begin staining your brand new dentures. All the other horrible things that smoking can do to your body you already know about and have chosen to ignore. Please, use this experience as a reason to quit.
