Smoking is not an absolute contraindication to dental implants, but it is the single most significant modifiable risk factor. Heavy smokers have 2–3× the implant failure rate of non-smokers. For full-arch cases, the differential is often larger.
Why Smoking Hurts Implants
- Vasoconstriction — nicotine constricts blood vessels, reducing oxygen and nutrient delivery to healing bone and soft tissue.
- Impaired wound healing — smokers consistently show delayed and poorer-quality healing across every type of surgery.
- Soft-tissue damage — combustion byproducts cause chronic inflammation around implants.
- Worse peri-implantitis outcomes — once peri-implant infection begins in a smoker, it progresses faster and responds to treatment less reliably.
What Quitting Actually Does
Research suggests that stopping smoking for as little as 2 weeks before implant surgery and 8 weeks after reduces failure rates significantly. Longer-term quitting brings failure rates back toward non-smoker baselines. Even partial reductions help.
What About Vaping?
The data is less mature than for combustible cigarettes, but vaping still delivers nicotine (which causes the vasoconstriction) and has documented effects on oral soft tissue and wound healing. We treat vaping as a significant risk factor, not a safe substitute.
How We Modify Treatment for Smokers
- Extended healing time before loading
- Prophylactic antibiotics in appropriate cases
- More frequent maintenance visits (typically every 3 months)
- Preference for screw-retained prosthetics for easier maintenance access
- Counseling on smoking cessation — not moralizing, but honest about the effect on outcomes
Should Smokers Skip Implants?
No. Even at 2–3× the failure rate, success rates for smokers still exceed 85–90% in most studies. The honest framing: smoking meaningfully reduces your chances of a perfect long-term outcome, but does not preclude a good one. We are direct with patients about this at consultation.
