Why tobacco fails implants
Nicotine and carbon monoxide reduce gum and bone vascularization. Result: bone around the implant heals slower and less well, and incomplete osseointegration risk multiplies by two or three in smokers of over 10 cigarettes a day.
The numbers to know
In non-smokers, 10-year implant success rate is 96-98%. In active smokers, it drops to 82-90% depending on studies — three times more failures. Significant but not disqualifying, provided the right protocol is applied.
Minimum temporary cessation
International protocol recommends: complete stop two weeks before surgery and 6-8 weeks after. It's the critical bone-healing phase. Reduced return afterward (under 10/day) remains preferable, but the key window is these 8-10 weeks.
Nicotine substitutes: allowed or not?
Patches and nicotine gum should be avoided in the first 3 post-op weeks (nicotine alone is still vasoconstrictor). E-cigarettes pose the same issue. In practice, a real 4-6 week break is most effective.
If cessation is impossible
A smoker who can't stop remains an implant candidate, but with close follow-up, extended antibiotics, and often an adjusted warranty. The quote factors this in. Worst case is smoking without disclosing and compromising success.
Tobacco doesn't forbid implants — it imposes strict temporary cessation. Two months off restores near-normal success rate. Bring it up from the first consultation; it's a clinical topic, not a moral one.
