Smoking and teeth: cigarettes, e-cigarettes, heated tobacco and nicotine pouches, and their effect on gums and implants

How does smoking cigarettes affect the gums and teeth?

Smoking cigarettes harms above all the gums and the bone around the teeth: a 2018 meta-analysis by Leite et al., based on prospective studies, found that smoking increases the risk of periodontitis (gum disease) by about 85% (RR 1.85). The authors cite the hypothesis that tobacco disrupts the immune response and the blood supply of the periodontal tissues.

Under the 2018 classification of periodontal diseases, risk factors, including smoking, change the assessment of how fast the disease progresses. In its 2020 guidelines, the European Federation of Periodontology (EFP) names smoking and diabetes as the two main risk factors for periodontitis.

The effects are not limited to the gums. Smoking increases the risk of implant failure and of dry socket after a tooth extraction, stains the enamel and is one of the risk factors for cancers of the mouth and throat, as the following sections explain.

Why do smokers’ gums bleed less often?

Smokers’ gums bleed less often because smoking suppresses bleeding, not because the gums are healthier. A study by Dietrich et al. (2004) of more than 12,000 people from the US NHANES III survey found a strong, chronic and dose-dependent suppression of bleeding on probing, strongest in people smoking more than 10 cigarettes a day.

At healthy sites, the odds of bleeding in heavier smokers were clearly lower than in non-smokers (odds ratio 0.56). In non-smokers, sites with calculus or a deepened pocket bled much more often than healthy ones, while in heavy smokers this relationship was barely visible.

In a smoker, the absence of bleeding is therefore no proof of healthy gums. The disease can develop silently, which is why a pocket examination at the dentist says more about the state of the periodontium than what you see when brushing.

Smoking, implants and healing after tooth extraction

Smoking roughly doubles the rate of implant failure: in a review of 107 studies, implants failed in 6.35% of smokers compared with 3.18% of non-smokers, and another meta-analysis gives a relative risk of 1.92. The 2017 World Workshop on classification judged the link between smoking and inflammation of the tissues around an implant (peri-implantitis) inconclusive.

After a tooth extraction, smoking increases the risk of dry socket: a review by Kolokythas et al. gives 12% in smokers compared with 2.6% in non-smokers. When you can go back to cigarettes after an extraction is covered in the article on aftercare following tooth extraction, and the risk factors for implants in the article on whether implants last a lifetime.

Smoking does not rule out implant treatment, but it is a factor the dentist takes into account in the plan. Stopping or cutting down on smoking is worth discussing with the dentist while treatment is still being planned.

E-cigarettes, heated tobacco and the gums: what is known?

Little is known about the effect of e-cigarettes on the gums, and the available studies are of low quality. A review of 40 studies by Tattar et al. (2025) found that cigarette smokers had the worst results, while e-cigarette users showed no differences in pocket depth or bone loss compared with non-smokers; they did, however, have more plaque and higher markers of inflammation.

A 2024 meta-analysis of 12 studies found no significant link between e-cigarettes and attachment loss or pocket depth, but did find less bleeding on probing than in non-users, with very high inconsistency between the results. The authors of both papers stress the limitations of the available data, and the authors of the 2024 meta-analysis call for longer observational studies.

For heated tobacco there are even fewer data on gums and teeth: mainly small cross-sectional and laboratory studies. The World Health Organization (WHO) points out that reduced exposure to some harmful substances does not make these products harmless or mean a lower risk to health, and that some toxins are present at higher levels in their aerosol than in cigarette smoke.

Nicotine pouches, snus and the gums

Nicotine pouches and snus act mainly locally, at the spot where they are held under the lip. In a 2026 Swedish cross-sectional study (people aged 18 to 30), 79% of nicotine pouch users and 89% of tobacco snus users had changes in the oral mucosa; redness was more common with pouches, and thickening of the epithelium with snus.

In the same study, use for up to 6 years was not associated with a higher risk of tooth decay or periodontal disease. An earlier study of 19-year-olds in Gothenburg found, however, that 42% of snus users had gum recession compared with 17% of the control group, meaning that the gum receded more often, especially at the upper front teeth.

Changes where a pouch is held are described as usually reversible once use stops. A white patch, an ulcer or a receded gum at that spot is a reason to show it to a dentist.

Cigarettes, e-cigarettes and pouches: the evidence compared

The evidence of harm to the mouth varies in strength from product to product: it is strongest for cigarettes and weakest for new products that have only recently come onto the market. The table summarises what the studies cited show and rates the strength of the evidence.

Smoking stains and changes in the mouth: what to watch for?

Smoking stains are extrinsic stains that build up on the surface of the enamel, much like those from coffee or tea. They are usually removed by professional cleaning, and what remains can be lightened by whitening; the details are in the article on tooth discolouration.

Smoking is one of the risk factors for cancers of the lip, mouth and throat listed by the Polish National Cancer Registry (Krajowy Rejestr Nowotworów), alongside spirits and HPV infection. An ulcer that has not healed for more than 3 weeks, as well as a red or red-and-white patch or a lump in the mouth, needs to be seen by a dentist or a doctor.

UK prevention guidelines recommend that dentists look at and feel the whole mouth at every check-up. For smokers, regular check-ups therefore matter twice over: for the gums and for the oral mucosa.

How to stop smoking: where to get help in Poland?

Stopping smoking pays off for the gums: a 2019 meta-analysis by Leite et al. found that in people who had quit, the risk of periodontitis developing or progressing did not differ significantly from that of people who had never smoked, and periodontal treatment gave them better results. The EFP recommends that help with quitting be part of periodontal treatment.

Free help is available from the Telephone Helpline for Smokers (Telefoniczna Poradnia Pomocy Palącym), run by the National Institute of Oncology: 801 108 108 or 22 211 80 15, Monday to Friday from 9:00 to 21:00 and on Saturdays from 9:00 to 15:00. The NFZ (Poland’s National Health Fund) runs a programme for the prevention of tobacco-related diseases, which also covers users of heated tobacco and e-cigarettes.

The basic stage of the programme, smoking cessation counselling, is for people over 18, and the specialist stage is for dependent people over 16, also without a referral. It includes, among other things, measuring carbon monoxide in exhaled air and a treatment plan with medication or psychological therapy. Providers are listed in the NFZ search tool “Gdzie się leczyć” (Where to get treatment) or by the helpline on 800 190 590. Legal position as of 18 October 2026.

How it works at DentalBlue

At DentalBlue in Białystok, gum disease is treated in periodontology, and prevention includes professional cleaning, which removes tartar and stains from the tooth surfaces. Implants are planned on images from cone beam computed tomography (CBCT) taken in the clinic’s own radiology unit.

In the clinic’s price list, “Kompleksowa higienizacja (skaling, piaskowanie, fluoryzacja)” (comprehensive hygiene treatment: scaling, air polishing, fluoride treatment) costs 350 zł, and “Konsultacja periodontologiczna” (periodontal consultation) 300 zł. The final scope and cost are set at the visit, and prices may change.
