TL;DR Smoking is one of the biggest avoidable risks to your gums, raising the risk of gum disease, staining, bad breath, slow healing, failed implants and mouth cancer. Vaping looks less harmful to your mouth than smoking, but it is not risk-free and its long-term effects are unknown. Stopping completely is best, and free NHS help is available.
Perhaps you switched from cigarettes to a vape and wondered whether your gums are actually better off. Perhaps you have noticed stains, a stale taste or gums that look different, and you are worried about what your dentist will say. Or perhaps you use nicotine pouches, snus or paan and have never been sure how they compare.
This guide explains what the evidence says about smoking, vaping and other nicotine and tobacco products and your teeth and gums, what is known and what is not, why it is worth telling your dentist what you use, and where to get free help to stop across the UK. It draws on NHS (National Health Service) information, the government's Delivering Better Oral Health toolkit for dental teams, NICE guidance and recent systematic reviews. It is general information, not a diagnosis: your dentist, who can examine your mouth, is the best person to tell you how your habits are affecting it.
Smoking, vaping and your mouth at a glance
| Product | Gums | Staining and breath | Healing and implants | Mouth cancer | Strength of evidence |
|---|---|---|---|---|---|
| Cigarettes | Much higher risk of gum disease; treatment works less well [3][22] | Stains teeth and causes bad breath [5][6] | Higher risk of dry socket and implant failure [21][23] | Major risk factor [7] | Strong, decades of research |
| Vapes (e-cigarettes) | Appears less harmful than smoking, but worse than not using anything [3][24] | Not listed by the NHS as a cause; research limited | Too little data to say | Long-term risk unknown [8] | Limited, mostly small and short-term studies |
| Snus, chewing tobacco and paan | Snus linked to receding gums [29] | Not covered by the sources used here | Too little data to say | All legal forms of tobacco carry an oral cancer risk [2][7] | Moderate |
| Tobacco-free nicotine pouches | Early studies show less irritation than tobacco, no long-term data [30] | Not established | Not established | Unknown [30] | Very limited |
The rest of this guide explains each row, with the source behind every claim.
How many people smoke and vape in the UK
Smoking is less common than it used to be, but millions of people still smoke or vape. The ONS (Office for National Statistics) reported in October 2026 that "Around 4.9 million people aged 18 years and over (9.8% of the population) smoked cigarettes in the UK in 2025." [9] It also found that "around 5.4 million adults aged 16 years and over (9.9%) used an e-cigarette daily or occasionally in 2025" in Great Britain [9]. The two figures come from different surveys covering different age groups and areas, so they are not a like-for-like comparison.
The law is changing too. The ban on single-use vapes "came into force on 1 June 2025", making it illegal for businesses to sell or supply them [10]. The Tobacco and Vapes Bill received Royal Assent on 29 April 2026, with the government describing it as "making it illegal to sell tobacco to anyone born on or after 1 January 2009" [11]. NHS.uk notes that "From 2027, a new law will mean some people will never be sold tobacco products in their lifetime." [13]
How smoking affects your teeth and gums
Gum disease
Gum disease is one of the main dental reasons to stop smoking. The NHS explains that "Gum disease is caused by a build-up of plaque on your teeth", and lists stopping smoking among the things a dentist will advise: they may "advise you to stop smoking, if you smoke" [4].
The government's Delivering Better Oral Health toolkit, an evidence-based prevention guide for dental teams, is blunt about tobacco. It says tobacco use "is also the most common risk factor for periodontal disease" [2], and that "Tobacco smoking and use of smokeless tobacco products have a profound effect on the risk of developing periodontitis. They also impair the treatment response." [3] Periodontitis is the more advanced form of gum disease, where the bone and tissue holding the teeth in place are damaged.
Research puts a number on it. A 2018 systematic review and meta-regression in the American Journal of Preventive Medicine concluded that "smoking increases the risk of periodontitis by 85%" [22]. In practice, this means that a smoker is far more likely to develop the kind of gum disease that can loosen teeth, and that deep cleaning and other gum treatment tends to work less well while they keep smoking [3].
If you would like to understand gum disease symptoms in more detail, our guide to bleeding gums: causes, treatment and when to see a dentist covers the warning signs, and our receding gums guide explains what happens when gums pull back from the teeth.
Bleeding gums can be a less reliable warning sign
Bleeding when you brush is usually one of the first signs of gum disease. In smokers, though, it may be a less dependable signal. A 2025 systematic review of 13 studies in Health Science Reports found that cigarette smokers had worse periodontal conditions overall but "lower Bleeding on Probing" than other groups [26]. The evidence on this is not unanimous, but it is a reason not to rely on bleeding alone.
The practical point is simple: if you smoke, the absence of bleeding does not mean your gums are healthy. Regular check-ups matter, because a dentist or hygienist can measure the gaps around your teeth and spot gum disease that you cannot feel or see.
Staining and bad breath
Two of the most visible effects of smoking are on your smile and your breath. The NHS lists "smoking" among the causes of stained or darker teeth, alongside "getting older" and drinks such as "coffee, tea or red wine" [6], and lists smoking as a cause of bad breath [5]. The NHS bad breath page also notes that gum disease and dry mouth can cause bad breath [5].
Our guides to teeth stains and discolouration and bad breath (halitosis) explain the removal and treatment options, including what a scale and polish can and cannot do.
Slower healing and dry socket after extractions
Smoking also affects how well your mouth heals. A 2022 systematic review in Dentistry Journal concluded: "Based on a meta-analysis, tobacco smokers had a more than three-fold increase in the odds of dry socket after tooth extraction. Overall, the combined incidence of dry socket in smokers was found to be about 13.2% and in non-smokers about 3.8%." [23] Dry socket is a painful condition where the blood clot in the empty socket is lost or fails to form.
If you are having a tooth out, tell your dentist that you smoke and follow their aftercare advice closely.
Dental implants
Smoking is one of the most important factors in whether a dental implant lasts. A 2015 systematic review and meta-analysis in the Journal of Dentistry pooled data on more than 80,000 implants. It found "19,836 implants placed in smokers, with 1259 failures (6.35%), and 60,464 implants placed in non-smokers, with 1923 failures (3.18%)" [21], roughly double the failure rate, although the authors noted that the results should be read with caution because of confounding factors.
Delivering Better Oral Health takes a measured line, describing "low certainty evidence that the placement of implants in smokers is associated with implant failure" [3]. A 2026 systematic review in Clinical Oral Implants Research reached a similar conclusion: "Although tobacco smoking is not considered an absolute contraindication for implant therapy, evidence indicates that it has a detrimental effect on peri-implant tissues, leading to an increased risk of implant failure and crestal bone loss." [28]
In other words, smoking does not automatically rule out implants, but your dentist will want to talk about it before you commit to the cost. Our dental implants cost guide explains NHS and private options.
Mouth cancer
The most serious risk is mouth cancer. The NHS lists the risk factors as including when "you smoke or chew tobacco, betel nut or paan" and when "you drink a lot of alcohol" [7]. Delivering Better Oral Health states that for tobacco users "The most significant risk is for oral cancer and pre-cancer" [2].
The NHS says symptoms of mouth cancer can include "a mouth ulcer in your mouth that lasts more than 3 weeks" and "a red or white patch inside your mouth" [12]. If you notice either, see a dentist or GP. Our guide to mouth cancer symptoms and when to see a dentist covers the signs and the referral process in detail.
Does vaping damage your teeth and gums
This is the question many people searching online really want answered, and the honest answer is that vaping appears to be less harmful to your mouth than smoking, but it is not harmless, and nobody yet knows its long-term effects.
What UK health bodies say
The NHS position on vaping is clear: "Nicotine vaping is less harmful than smoking. However, vaping is not risk-free." [1] It adds that while vaping is less harmful than smoking, "it is unlikely to be totally harmless", and that "Children and non-smokers should never vape." [1]
NICE (the National Institute for Health and Care Excellence) asks health professionals to explain that "there is not enough evidence to know whether there are long-term harms from e-cigarette use" and that "use of e-cigarettes is likely to be substantially less harmful than smoking" [8].
The dental guidance says much the same. Delivering Better Oral Health states that "E-cigarettes or vapes are not risk free but are far less harmful than cigarettes" [2]. On gums specifically, it notes that studies on vaping "are inconsistent but suggest people who vape are at greater risk for periodontal diseases compared to non-smokers", while recognising "that most people who vape are former smokers and will have experienced the effect of smoking on their periodontal health" [3]. It adds that e-cigarettes "may, however, have a lower risk of periodontitis than tobacco and therefore provide a helpful transition to cessation for smokers" [3].
What the research shows
Several systematic reviews published in 2025 and 2026 point in the same direction:
- A 2026 review of 31 studies in Dentistry Journal found that e-cigarette users had deeper gum pockets and more attachment loss than non-smokers, and concluded: "Smoking negatively affects periodontal and peri-implant status, with CS exhibiting the worst impact. E-Cigs and HTPs appear less harmful but are not risk-free." [24] (CS means cigarette smokers and HTPs means heated tobacco products.)
- A 2026 review of 7 studies in Clinical and Experimental Dental Research looked at how well gum and implant treatment works. It found "no significant difference in clinical response to periodontal and peri-implant therapy between tobacco and e-cigarette users, both of whom fared worse than non-smokers." [25]
- A 2025 review of 13 studies in Health Science Reports concluded: "While vaping seems to have a lower influence on periodontal health, it deserves further examination." [26]
- An earlier 2020 review in Critical Reviews in Toxicology concluded that "Although switching to e-cigarettes may mitigate oral symptomatology for conventional smokers, findings from this review suggest that a wide range of oral health sequelae may be associated with e-cigarette use." [31]
These studies have real limitations. Most are small or short-term, and because many vapers used to smoke, it is hard to separate the effects of vaping from the damage that smoking had already done.
Staining, decay and dry mouth from vaping
You will find many claims online that vaping stains teeth, causes tooth decay or dries out your mouth. The NHS pages on stained teeth and bad breath list smoking as a cause but do not list vaping [5][6], and we did not find a UK health body or a high-quality review that confirms these effects. The research is still emerging, so if you vape and notice a dry mouth, staining or new sensitivity, mention it to your dentist rather than assuming it is, or is not, caused by your vape.
The bottom line on vaping
If you smoke, switching completely to vaping is likely to be better for your mouth and your general health than carrying on smoking, and the NHS supports vaping as a way to quit [1]. If you do not smoke, do not start vaping. The best outcome for your teeth and gums is to stop using nicotine products altogether when you are ready.
Nicotine pouches, snus, chewing tobacco and paan
Smokeless products are not a safe alternative for your mouth.
- Chewing tobacco, betel nut and paan. The NHS lists chewing these as mouth cancer risk factors [7]. Delivering Better Oral Health states that "All forms of tobacco that are legal in the UK present an oral cancer risk" [2], and notes that betel quid (paan) with areca nut is especially common within South Asian cultures [2]. NICE asks health professionals, including dentists, to make sure people who use smokeless tobacco "are aware of the health risks (for example, the risk of cardiovascular disease, oropharyngeal cancers and periodontal disease)" [8].
- Snus. A 2026 systematic review in Acta Odontologica Scandinavica concluded that "Swedish snus is associated with gingival recession, particularly among users of loose snus", and that gum inflammation was more common among snus users [29].
- Tobacco-free nicotine pouches. These are newer, and the evidence is thin. A 2026 review in Frontiers in Oral Health found that "short-term clinical studies report reductions in oral mucosal irritation and gingival inflammation among exclusive users" compared with tobacco, but that "no long-term epidemiological evidence is currently available" on cancer risk [30]. In other words, nobody yet knows their long-term effect on your gums.
If you use any of these products, tell your dentist, using whatever name you know the product by, so they can check the areas where you hold it.
What happens to your mouth when you stop
The good news is that stopping helps, whatever your age and however long you have smoked. Delivering Better Oral Health states that "Cessation of tobacco use can prevent further deterioration of periodontal health" [3].
A 2026 network meta-analysis in Dentistry Journal compared how well non-surgical gum treatment worked in different groups. It found that former smokers and people who had quit "showed no statistically significant differences" from people who had never smoked, although the groups were small and "The certainty of evidence varied across exposure groups and outcomes." [27]
Note the wording of the guidance: stopping prevents further deterioration. It does not reverse every change that has already happened, which is why it is worth having your gums checked when you quit. Quitting gives gum treatment a better chance of working, and it lowers your future risk.
Telling your dentist that you smoke or vape
Many people feel embarrassed about admitting to smoking or vaping. There is no need. The NHS explains that at a check-up the dental team may ask "about your diet, and if you smoke or drink alcohol" [12], and Delivering Better Oral Health says all adolescent and adult patients should have their smoking status established [2]. You are not being singled out.
Delivering Better Oral Health asks dental teams to deliver "ask, advise, act" very brief advice (VBA) to smokers, explaining that this "has been shown to increase a patient's motivation to quit and can double a patient's success with quitting smoking" [2]. It also tells them to "Keep asking and advising because it will make a difference" [2].
Being honest helps your dentist to:
- check more carefully for gum disease, especially as bleeding may be less obvious [26]
- plan extractions and implants with your healing in mind [21][23]
- examine the areas where you hold a pouch, snus or paan
- refer you to free stop smoking support if you want it
If you have switched completely to vaping, say so. Delivering Better Oral Health states that "People who have completely switched to vaping should be recorded as non-smokers in dental records." [2]
Free help to stop smoking across the UK
You do not have to quit alone, and NHS support is free.
- England. Your local Stop Smoking Service is free, and the NHS says "with professional or expert help, you're 3 times more likely to quit for good." [14] Services may offer a free vaping starter pack [1], and you can also use the NHS Quit Smoking app [13].
- Scotland. Quit Your Way Scotland offers free advice on 0800 84 84 84, Monday to Friday, 9am to 5pm [15].
- Wales. Help Me Quit offers free support on Freephone 0800 085 2219 [16].
- Northern Ireland. The Public Health Agency's Stop Smoking NI website lists stop smoking services across Northern Ireland [17].
NICE guidance lists the support that can help people stop, including behavioural support, nicotine replacement therapy (NRT), stop smoking medicines such as varenicline, and nicotine-containing e-cigarettes [8].
Check-ups and NHS dental costs
If you smoke, vape or use other nicotine products, regular check-ups are one of the best things you can do for your mouth. Your dentist will recommend how often you need to be seen based on your own risk, so tell them about your smoking, vaping or nicotine use. Our guide to how often you should visit the dentist explains how recall intervals are set.
NHS charges in England
NHS dental treatment in England is charged in three bands [18][19]:
| Band | Current charge | What it covers |
|---|---|---|
| Band 1 | £27.90 | Examination, diagnosis and advice, X-rays, scale and polish if clinically needed, and planning further treatment |
| Band 2 | £76.60 | Everything in Band 1, plus treatment such as fillings, root canal treatment and extractions |
| Band 3 | £332.10 | Everything in Bands 1 and 2, plus more complex treatment such as crowns, dentures and bridges |
Clinically necessary gum treatment is available on the NHS within these bands, so ask your dentist which band your treatment falls under. Our guide to NHS dental charges explains the bands in full, and our gum disease treatment cost guide compares NHS and private costs.
Who gets free NHS dental treatment
In England, NHS dental treatment is free if, for example, you are "aged under 18, or under 19 and in full-time education", you are "pregnant or have had a baby in the last 12 months", you or your partner receive certain benefits such as Income-related Employment and Support Allowance, Pension Credit Guarantee Credit or Universal Credit (only if your income is below a certain amount), or you hold a valid HC2 certificate [20]. See our free NHS dental treatment eligibility guide for the full list.
Scotland, Wales and Northern Ireland
Charges differ across the UK. In Scotland, "Everyone in Scotland is entitled to free NHS dental examinations", and NHS dental treatment is free for everyone aged under 26 [32]. Adults who pay contribute 80% of the cost of treatment, capped at £384 per course [32]. Wales and Northern Ireland have their own NHS dental charging systems, so ask the practice for the cost before treatment starts.
Private treatment
Private fees for check-ups, hygienist appointments, gum treatment and implants vary from practice to practice. Ask for a written treatment plan and estimate before you agree to anything, and check whether the practice offers payment plans.
If you cannot find an NHS dentist
We know that finding an NHS dentist taking on new patients is genuinely difficult in many parts of the UK. Our guide on how to find an NHS dentist accepting new patients explains where to look and what to do if you need urgent care in the meantime.
Signs to discuss with your dentist
Whether you smoke, vape, use pouches or have recently quit, book an appointment if you notice:
- gums that bleed, look red or swollen, or are pulling back from your teeth
- teeth that feel loose or have moved
- bad breath or a bad taste that does not go away
- a mouth ulcer that lasts more than 3 weeks, or a red or white patch inside your mouth [12]
- a lump in your mouth, on your lip or in your neck [12]
- soreness or changes where you usually hold a pouch, snus or paan
These are signs to get checked, not a diagnosis. Most turn out to be something treatable, but early checks make treatment simpler.
Frequently asked questions
Does vaping damage your teeth?
Vaping appears less harmful to your teeth and gums than smoking, but it is not risk-free. Recent reviews found vapers had worse gum health than non-smokers, although better than smokers [24]. The NHS says "vaping is not risk-free" [1], and NICE says there is not enough evidence on long-term harms [8].
Does vaping stain your teeth?
The NHS lists smoking, not vaping, as a cause of stained teeth [6], and we found no UK health body or high-quality review confirming that vaping stains teeth. Research into vaping and the mouth is still limited. If you notice new staining, ask your dentist, who can identify the cause and suggest a professional clean.
Is vaping better for your gums than smoking?
The evidence suggests yes, but vaping is not as good as using nothing. A 2026 review of 31 studies concluded that e-cigarettes "appear less harmful but are not risk-free" [24]. Delivering Better Oral Health says vaping may carry a lower risk of gum disease than tobacco and can help smokers quit [3].
Can vaping cause gum disease?
It may increase the risk. Delivering Better Oral Health says studies "suggest people who vape are at greater risk for periodontal diseases compared to non-smokers", while noting most vapers are former smokers [3]. Evidence is limited and mostly short-term, so keep up regular check-ups and good brushing and flossing habits.
Does smoking cause gum disease?
Gum disease is caused by plaque, but smoking makes it far more likely and harder to treat. A 2018 meta-analysis found "smoking increases the risk of periodontitis by 85%" [22]. Delivering Better Oral Health calls tobacco "the most common risk factor for periodontal disease" and says it impairs the treatment response [2][3].
Can I have dental implants if I smoke?
Possibly. Smoking is "not considered an absolute contraindication for implant therapy", but it increases the risk of implant failure and bone loss [28]. One meta-analysis found failure rates of 6.35% in smokers against 3.18% in non-smokers [21]. Your dentist will discuss your risk and may encourage you to stop first.
Should I tell my dentist I vape or smoke?
Yes. Dental teams routinely ask whether you smoke [12], and knowing helps them check for gum disease, plan extractions and implants, and offer support to quit. If you have completely switched to vaping, say so: guidance says you should be recorded as a non-smoker in your dental records [2].
Do nicotine pouches damage your gums?
Nobody knows yet. A 2026 review found short-term studies reporting less mouth irritation and gum inflammation than with tobacco products, but "no long-term epidemiological evidence is currently available" [30]. Snus, which contains tobacco, is linked to receding gums [29]. Tell your dentist if you use pouches so they can check your gums.
Will my gums recover if I stop smoking?
Stopping helps. Delivering Better Oral Health says quitting "can prevent further deterioration of periodontal health" [3], and a 2026 analysis found former smokers responded to gum treatment similarly to non-smokers [27]. It will not reverse every change, so have your gums checked by a dentist when you quit.
Find a dentist for regular check-ups
Whether you smoke, vape or have just quit, a dentist who knows your mouth is your best early-warning system. Regular check-ups catch gum disease and other changes early, when treatment is simplest, and your dental team can point you towards free support to stop.
When you are ready, search for a dentist near you on Dentists Closeby to compare NHS and private practices in your area and find one that suits you.
