TL;DR
Smoking increases the risk of implant failure by 2 to 3 times. Smokers can still get implants — but only with realistic counselling, stricter follow-up care, and ideally a smoking break before and after the procedure. This article explains exactly what happens, which risks are real, and what you can do to improve your chances.
Many patients who smoke ask: "Can I still get an implant?" The honest answer is: yes — but with significantly higher risk. Smoking is one of the best-documented risk factors for dental implant failure. This is not because dentists discriminate against smokers, but because of biology: nicotine and carbon monoxide directly affect how well bone and tissue heal after surgery.
This guide explains what happens in a smoker's body after implantation, how large the risk really is, what you can concretely do — and when an implant makes sense despite smoking.
What smoking does in an implant patient's body
Nicotine constricts blood vessels — this is the core mechanism behind almost all problems. Less blood flow means less oxygen and nutrients in the tissue that needs to heal after implantation. At the same time, smoking inhibits the activity of osteoblasts, the cells that build new bone. The result: osseointegration — the implant growing into the bone — proceeds more slowly and less completely.
In addition, smokers have a significantly weakened immune system in the oral area. The risk of peri-implantitis — a bacterial inflammation around the implant — is significantly elevated in smokers. Peri-implantitis is the most common cause of late implant failure.
| Risk Factor | Non-smoker | Smoker |
|---|---|---|
| Implant failure (early) | 1–2% | 4–6% |
| Implant failure (late) | 2–3% | 6–10% |
| Peri-implantitis risk | approx. 10% | approx. 25–30% |
| Healing time after implantation | Standard | +20–40% longer |
| Bone loss after 5 years | 0.5–1 mm | 1.5–2.5 mm |

Important to know
The risk increases with the number of cigarettes smoked daily and the duration of smoking. Heavy smokers (more than 10 cigarettes per day) have up to 3 times higher implant failure risk than non-smokers.
How long before implantation should you stop smoking?
The good news: even a temporary smoking break measurably improves healing chances. Studies show that patients who stopped smoking at least one week before the procedure had significantly better healing outcomes than those who smoked up until the day of implantation.
A smoking break of at least two weeks before the procedure and at least eight weeks afterwards is recommended — during the critical phase of osseointegration. Those who quit permanently gradually approach the risk profile of a non-smoker.
Recommendations for smokers before and after implantation
Stop smoking at least 2 weeks before the procedure
Stay smoke-free for at least 8 weeks after implantation
Schedule more frequent check-ups (every 3 instead of 6 months)
Professional teeth cleaning before and after the procedure
Be open with your doctor about smoking habits — no downplaying
E-cigarettes are not safe — nicotine is still nicotine
Are e-cigarettes a safe alternative?
Many patients ask whether they can switch to e-cigarettes. The answer is clear: no, not as a "safe" alternative for implant patients. E-cigarettes contain nicotine — and nicotine is the main culprit in vasoconstriction and impaired bone healing. Whether the nicotine is absorbed through combustion or vaporisation makes no significant difference to the healing process.
Nicotine patches and gum for smoking cessation are also problematic if used during the critical healing phase. Those who seriously want to quit should discuss the topic with their doctor and consider pharmacological support (e.g. varenicline) if appropriate.
When is an implant worthwhile despite smoking?
Smoking is not an absolute contraindication for implants. It is a risk factor that is factored into the overall assessment. If all other prerequisites are good — sufficient bone, good oral hygiene, no uncontrolled systemic diseases — an implant can still be a sensible option for smokers.
Occasional smokers (fewer than 5 cigarettes per day) have a significantly lower risk than heavy smokers. In very heavy smokers with existing bone loss and poor oral hygiene, an implant may actually be contraindicated — at least until smoking cessation has been successfully achieved.
Frequently asked questions from smokers about implants
Do I have to tell my dentist that I smoke?
Yes, absolutely. Smoking affects treatment planning, follow-up care and risk counselling. Anyone who conceals this harms themselves — and may have no recourse if something goes wrong.
Can I start smoking again after implantation?
Technically yes, but medically not recommended. The peri-implantitis risk remains permanently elevated as long as you smoke. Resuming after the procedure significantly increases the long-term failure risk.
Are there special implants for smokers?
No. There are no implants specifically designed for smokers. Some implant systems with rougher surface profiles show slightly better osseointegration in studies — but this does not fully compensate for the smoker's risk.
Does insurance cover implant failure due to smoking?
It depends on the insurance contract. Many insurers exclude implant failure due to known risk factors. Clarify this with your insurer before treatment.
Conclusion
Smoking and implants are not mutually exclusive — but they do not get along well. Those who smoke and want implants need honest counselling, a realistic risk assessment and the willingness to take follow-up care more seriously than a non-smoker. The best decision is always the informed decision.
Digital Diagnostics for Smokers
For smokers, precise pre-operative diagnostics are especially important: a DVT (digital volume tomography) reveals not only bone quantity and quality, but also allows assessment of the blood supply situation in the jaw bone. Smoking-related bone changes are detectable early in the 3D image — and feed directly into the individual risk assessment.
