Smoking and implants: an honest conversation about risk, timing and what actually helps

Key points

• Implants are placed for smokers. But the risk that an implant fails to integrate, or becomes inflamed later, is roughly twice as high in smokers — confirmed by dozens of studies.
• The riskiest period is the first two weeks after surgery: nicotine narrows blood vessels, and hot smoke and drawing on a cigarette injure the wound.
• A pause of 1–2 weeks before surgery and at least 2–4 weeks afterwards noticeably lowers the risk. Quitting entirely brings the risk down to that of non-smokers within a year.
• Vaping and shisha are not a "safe substitute" — nicotine and heat act the same way.
• The clinic does not turn away a smoking patient, but it tells them the truth about the risks and offers a plan.

What smoking actually does to an implant

Three mechanisms, and all of them come down to blood flow and healing.

Nicotine narrows blood vessels. The bone and gum around an implant heal thanks to blood supply. In a smoker, blood flow in the gum is chronically reduced, and every cigarette adds a spasm lasting 30–40 minutes. The cells that are supposed to build bone around the titanium get less oxygen — integration is slower and does not always finish.

Smoke and heat injure the wound. In the first days after surgery there is a fresh suture over the implant. Hot smoke dries and irritates it, and the suction of drawing on a cigarette creates negative pressure in the mouth that can dislodge the clot and open the wound to infection.

Smoking changes the oral flora. Smokers carry more of the bacteria that cause gum inflammation and have a weaker immune response. This works not just in the first weeks but for years: peri-implantitis — inflammation of the bone around an implant — is noticeably more common in smokers.

Numbers, not scare stories

According to meta-analyses, implant loss in smokers happens roughly twice as often as in non-smokers: roughly 6–8 cases per hundred implants versus 3–4. In other words, implants integrate successfully in most smokers. But "twice as often" is significant, especially with more than one implant — four or five, as in All-on-4/5 — and especially with a bone graft or sinus lift, where healing already takes longer.

The risk is dose-dependent: 5 cigarettes a day and 25 are different risks. And it is reversible: a year after quitting, the risk approaches that of non-smokers.

What actually helps

A pause before surgery — 1–2 weeks. In that time the gum's blood vessels partly recover, and the wound after surgery heals better.

A pause afterwards — at least 2 weeks, ideally 4–8. This is the primary healing period, when every cigarette causes direct harm. If you cannot stop entirely, cut down to a minimum and avoid smoking altogether for the first 72 hours.

Nicotine patches and gum are a compromise: the vessels still narrow, but there is no smoke, heat or suction. Discuss this with your doctor.

Stricter hygiene. For smokers: professional cleaning every 4 months rather than every six, and an implant check at every visit.

Honesty at the consultation. Tell the surgeon how much you smoke. This is not a reason for refusal — it is information for the plan: the surgeon may choose a different implant system, postpone immediate loading, or suggest staged implant placement instead of an All-on protocol.

Vaping, shisha, IQOS

All three contain nicotine, with the same effect on blood vessels. Shisha adds prolonged inhalation of hot vapour; vaping adds a glycerine film that dries the mucosa. From the implant's point of view there is almost no difference from cigarettes, and "switching to vaping during healing" is not a solution.

What this looks like at a consultation at the clinic

A smoking patient is not turned away. At the consultation the surgeon examines the CBCT scan and the gums — in long-term smokers the bone is often denser and the gum thinner, which is factored into the implant choice. Then comes an honest conversation: here is how much higher the risk is; here is what you can do before and after; here is how we will monitor you. The decision after that is the patient's.

Frequently asked questions

How soon after surgery can I smoke?

At least 72 hours, ideally 2 weeks; longer after a bone graft — the surgeon will give a timeline.

I've smoked for 20 years — is it worth quitting before implants?

Yes: even two smoke-free weeks improve healing, and a year almost equalises the risk with non-smokers.

Does implant failure from smoking happen right away?

Usually either in the first 2–3 months (the implant fails to integrate) or years later as peri-implantitis. Both are reasons to see a doctor immediately.

What happens if the implant still fails to integrate?

It is removed (50,000 ₸), the bone is given time to heal, and a new one is placed — often successfully. Check the warranty terms at the consultation.
