Dental implants are a possible option for smokers, however they are more likely to fail due to the adverse effects of smoking. If you currently smoke, but require dental implants then there are some considerations to be aware of. The procedure of placing dental implants becomes more complicated and once in place the implants are likely to have a reduced lifespan or even be more susceptible to failure. These possibilities are a risk for smokers and as such it is highly recommended that patients stop smoking altogether in preparation for dental implants.
If you smoke, you might not be the optimal candidate for dental implants. This is especially true for chain smokers. Though it might be possible to place dental implants in your mouth even if you smoke, the dentist might tell you the chances of the implants proving functional for years to come are considerably reduced due to your habit. Be completely honest when discussing dental implants with your dentist. If you smoke, tell your dentist and be realistic about whether you are willing to deal with the possibility of dental implant failure.
Though there are some dentists who will not hesitate to provide smokers with dental implants, many will refuse such a request. What matters the most for smokers is whether the gums and bones are strong enough to hold the dental implant in place. Bone grafting is an option if your bone/gums are deteriorated or in otherwise poor condition. However, some attempts at bone grafting have proved ineffective for those who smoke. The bottom line is smoking decreases the rate at which bone grows throughout the entirety of the body, including the mouth/face region.
