Smoking Dental Implants Australia: 5 Alarming Risks to Healing
By Michael Whelehan | Certified Master Hypnotherapist and Master NLP Practitioner | Breathe Hypnotherapy | Updated September 2026
Smoking dental implants is a combination that dentists and researchers treat with real caution. A 2026 systematic review in Clinical Oral Implants Research links tobacco smoking to a higher rate of implant failure, more bone loss around the implant, and a greater risk of biological complications such as peri-implantitis, an inflammatory condition that affects the tissue surrounding an implant.
If you are planning an implant, or already have one, here is what the research says about smoking dental implants and what changes if you quit.
1. Higher Implant Failure Rates
A review published in the Journal of Oral Biology and Craniofacial Research indexed on PubMed Central reports that clinical trials consistently rate smoking as a primary patient-centred risk factor for implant loss, with studies reporting failure rates in smokers ranging from 6.5 percent to 20 percent. That is a wide range, which is worth stating plainly. Study design, implant location, and how heavily participants smoked all influence the figures, so no single number applies to every smoker.
2. Nicotine Restricts Blood Flow to Healing Tissue
An implant needs to fuse with the jawbone and be surrounded by healthy gum tissue. The same review explains that nicotine absorbed into the bloodstream narrows blood vessels, and this vasoconstriction is considered a significant factor in implant failure in some studies. Less blood flow means less oxygen and fewer nutrients reaching the area during the critical healing period.
3. More Bone Loss Around the Implant
A 10-year prospective study of 453 implants found significantly higher bone loss around implants in smokers over time, and smokers also experienced a higher rate of implant failure, especially in the upper jaw. The authors concluded that smoking cessation should be advised and maintained after implant placement to help prevent peri-implant disease.
4. A Possible Link to Peri-Implantitis (The Evidence Is Mixed)
This is the part where the research does not fully agree, and it is important to say so. The same 10-year study found implants in smokers had a 2.6 times higher risk of developing peri-implantitis, but that result sat right at the edge of statistical significance. Its authors also note that most earlier studies failed to identify smoking as a clear risk factor for peri-implantitis specifically. The 2026 review does point to a study suggesting a direct link between cumulative smoking exposure and peri-implantitis risk. In plain terms, smoking dental implants clearly raises the risk of bone loss and failure, while its exact contribution to peri-implantitis is still being worked out.
5. The Upper Jaw Appears to Be More Vulnerable
Research reviewed in the PubMed Central article above found that in smokers, implants in the upper jaw fail more often than those in the lower jaw. The likely explanation is that upper jaw bone is typically lower in density and therefore more susceptible to the effects of smoking. If your planned implant is in the upper jaw, the case for quitting before treatment is stronger still.
What Changes When You Quit
The encouraging finding in the 2026 review is that one study reported a significant decrease in peri-implantitis risk as the number of years since quitting increased. Quitting does not undo everything overnight, but the direction of the evidence is consistent: the longer you stay smoke-free, the better the environment around an implant becomes.
Timing matters, and it is a decision for your dentist or oral surgeon rather than a general rule. If you have an implant planned, tell your dental team you smoke and ask how long before and after the procedure they want you smoke-free.

Why Willpower Alone Often Falls Short
Most people facing an implant already know smoking is not helping their mouth. Knowing that and being free of the habit are different things. Nicotine dependence runs on subconscious habit loops and stress responses, not just conscious decisions, which is why so many people who genuinely want to quit for a reason like this still find willpower-only attempts hard to sustain.
Important Disclaimer
Breathe Hypnotherapy does not provide dental advice and does not diagnose or treat implant failure, peri-implantitis, gum disease, or any other oral health condition. This article is general information about the documented link between smoking and dental implant outcomes, drawn from peer-reviewed international research, as no Australian-specific study was identified. Hypnotherapy at Breathe supports people to stop smoking or vaping. It is not a dental treatment. Speak with your dentist, periodontist, or oral surgeon about your individual situation and the right timing for any procedure.
