Can Smokers Get Dental Implants?

Smokers can get dental implants, but the procedure carries meaningfully higher risks compared to non-smokers. The decision to proceed is not a simple yes or no — it requires a clear understanding of the increased failure rates, a commitment to a smoking cessation plan around surgery, and realistic expectations about long-term outcomes. A 2014 meta-analysis published in the Journal of Dental Research analysing over 19,000 implants found that smoking increased the relative risk of implant failure by 2.23 times (Chrcanovic et al., JDR, 2014). Despite this, many smokers achieve successful implant outcomes, particularly when they reduce or quit smoking before and after the procedure. At Townsville Dental Clinic, we work with smoking patients to minimise risk and maximise the chance of a lasting result.

Why Smoking Increases Implant Failure Risk

The Science Behind the Risk

Tobacco smoke contains over 7,000 chemicals, but two are primarily responsible for the damage to dental implant healing.

Nicotine causes vasoconstriction — narrowing of blood vessels — which reduces blood flow to the gums and jawbone by up to 30 per cent. Adequate blood supply is essential for delivering the oxygen, nutrients, and immune cells needed for osseointegration (the process where bone fuses to the implant surface).

Carbon monoxide binds to haemoglobin in red blood cells 200 times more readily than oxygen, reducing the blood’s oxygen-carrying capacity. Even when blood reaches the surgical site, it delivers less oxygen than healing tissues require.

The combined effect creates a hostile environment for bone healing. New bone cells (osteoblasts) cannot proliferate and mineralise effectively without adequate oxygen, leading to incomplete or failed osseointegration.

Early Failure (0 to 6 Months)

Early implant failure occurs when the implant does not integrate with the bone during the healing phase. The implant becomes mobile and must be removed. Smokers are at greatest risk during this period because osseointegration is an active biological process entirely dependent on blood supply and oxygen delivery — both of which smoking compromises.

Late Failure (After Osseointegration)

Even after successful osseointegration, smokers face ongoing risks. Peri-implantitis — a chronic inflammatory condition that destroys bone around the implant — occurs more frequently and progresses faster in smokers. A study in Clinical Oral Implants Research found that smokers were three times more likely to develop peri-implantitis than non-smokers (Heitz-Mayfield & Huynh-Ba, COIR, 2009).

The Quit Timeline for Implant Candidates

Before Surgery

Cessation Period	Benefit
48 hours	Blood carbon monoxide levels normalise; oxygen delivery improves
2 weeks (minimum)	Gum tissue blood flow improves measurably
4 weeks (recommended)	Immune function begins to recover; white blood cell activity improves
8+ weeks (ideal)	Significant improvement in tissue healing capacity

After Surgery

Cessation Period	Benefit
48 hours (absolute minimum)	Reduces acute bleeding and clot disruption risk
8 weeks (minimum)	Covers the critical early osseointegration phase
3–6 months (ideal)	Covers the full osseointegration period
Permanently	Maximises long-term implant survival; prevents peri-implantitis

At Townsville Dental Clinic, we recommend a minimum of two weeks smoke-free before surgery and eight weeks after. However, the longer you can abstain — ideally permanently — the better your outcomes will be.

Cessation Support

Quitting smoking is difficult, but substantial support is available in Australia.

Quitline (13 78 48). Free telephone counselling and personalised quit plans.
Nicotine replacement therapy (NRT). Patches, lozenges, and inhalers available over the counter at pharmacies. Patches are preferred over oral NRT products during implant healing as they do not deliver nicotine directly to the surgical site.
Prescription medications. Varenicline (Champix) and bupropion (Zyban) can significantly improve quit rates. Discuss with your GP.
Your GP. Can develop a tailored cessation plan and prescribe medications. Medicare subsidises GP visits for smoking cessation under chronic disease management plans.

We can coordinate your implant treatment timeline with your cessation plan to give you the best window of smoke-free healing.

What If You Cannot Quit?

If quitting entirely is not achievable, the following measures help reduce — though not eliminate — the additional risk.

Cut down to fewer than five cigarettes per day. Research suggests a dose-dependent relationship between smoking volume and implant failure.
Do not smoke for at least 48 hours before and after surgery. This is the bare minimum.
Avoid smoking in the morning. Blood nicotine levels are highest after the first cigarette of the day.
Maintain impeccable oral hygiene. Brush twice daily, use interdental brushes, and rinse with chlorhexidine as directed.
Attend more frequent follow-up appointments. We may schedule check-ups every four to six weeks during the healing phase rather than the standard three-month intervals.

Alternatives to Dental Implants for Heavy Smokers

If the increased risk is unacceptable or if you are unwilling to modify your smoking habit, other tooth replacement options include:

Dental bridges. A fixed restoration that spans the gap of a missing tooth by crowning the teeth on either side. Bridges do not rely on osseointegration and are not directly affected by smoking’s impact on bone healing. However, smoking does increase the risk of decay and gum disease around the supporting teeth.

Partial dentures. A removable prosthesis that clips onto remaining teeth. Less invasive than implants or bridges but less stable and comfortable.

Full dentures. Replace all teeth in an arch. No surgical healing is required, but dentures rest on the gum and bone, which continues to resorb over time — a process accelerated by smoking.
