With a 95-plus percent survival rate after ten years, dental implants are one of the most durable replacement restorations available. Implants can potentially last much longer than less expensive options, which could make them a less costly choice in the long run.
But although a rare occurrence, implants can and do fail—often in the first few months. And tobacco smokers in particular make up a sizeable portion of these failures.
The reasons stem from smoking’s effect on oral health. Inhaled smoke can actually burn the outer skin layers in the mouth and eventually damage the salivary glands, which can decrease saliva production. Among its functions, saliva provides enzymes to fight disease; it also protects tooth enamel from damaging acid attacks. A chronic “dry mouth,” on the other hand, increases the risk of disease.
The chemical nicotine in tobacco also causes problems because it constricts blood vessels in the mouth and skin. The resulting reduced blood flow inhibits the delivery of antibodies to diseased or wounded areas, and so dramatically slows the healing process. As a result, smokers can take longer than non-smokers to recover from diseases like tooth decay or periodontal (gum) disease, or heal after surgery.
Both the higher disease risk and slower healing can impact an implant’s ultimate success. Implant durability depends on the gradual integration between bone and the implant’s titanium metal post that naturally occurs after placement. But this crucial process can be stymied if an infection resistant to healing arises—a primary reason why smokers experience twice the number of implant failures as non-smokers.
So, what should you do if you’re a smoker and wish to consider implants?
First, for both your general and oral health, try to quit smoking before you undergo implant surgery. At the very least, stop smoking a week before implant surgery and for two weeks after to lower your infection risk. And you can further reduce your chances for failure by practicing diligent daily brushing and flossing and seeing your dentist regularly for cleanings and checkups.
It’s possible to have a successful experience with implants even if you do smoke. But kicking the habit will definitely improve your odds.

Periodontal disease may start in the gums’ superficial layers, but it’s not likely to stay there. As the disease moves deeper it can wreak havoc on tooth roots and bone as well as gum tissue attachments. Teeth with multiple roots are in particular peril because of the “forks” called furcations that form where the roots separate from each other. Infected furcations can be very difficult to treat.
We primarily treat gum disease by removing its main source, a thin film of bacteria and food particles called dental plaque that builds up on teeth. To remove it we most often use special hand tools or ultrasonic equipment to vibrate it loose. As the plaque and tartar diminish, the infection begins to wane.
But we can’t be completely successful in stopping the disease if any lingering plaque deposits remain. This especially includes furcations where the infection can cause significant damage to the roots. Although cleaning furcations of plaque can be difficult, it’s not impossible with the aforementioned tools and antimicrobial substances to disinfect the area.
The real problem, though, is access—effectively getting to the furcations to treat them. We may need to perform a surgical procedure called flap surgery where we create a hinged flap in the gum tissue to move it aside and access the root area beneath. Afterward we replace the flap and suture the tissue back in place.
In some cases, the infection may have already caused significant damage to the tissue and underlying bone. We may therefore need to graft gum or bone tissues to these damaged areas to stimulate re-growth. We may also need to surgically reshape the gum attachments around a tooth to make it easier in the future to access and clean the area.
These additional treatments around furcations can be very involved and labor-intensive. That’s why the best outcomes occur if we’re able to start treatment in the early stages of an infection. So, if you notice red, swollen or bleeding gums contact your dentist as soon as possible. Treating gum disease as early as possible will help ensure your tooth roots won’t suffer extensive damage.
