What snus actually does to your mouth.
Straight answers on gum recession, the white patch, the burn and dry mouth: what the evidence says, what's overblown, and how to look after your gums if you're not ready to quit.
We make a nicotine-free pastille, so we're not a neutral party. That's why everything below is sourced, including the parts where the science genuinely isn't settled. Read the studies yourself — we'd rather earn your trust than oversell you.
§1In short: does snus damage your gums?
Yes — mostly where you place it, and mostly at the milder end. Soreness and irritation at the placement site are common and well documented. Localised gum recession is real but less universal; it shows up mainly where the pouch sits, over time. Dry mouth is one of the most commonly reported side effects. Snus is generally considered lower-harm than smoking — but "lower than cigarettes" is not "harmless", and none of it is for non-users or under-18s.
§2Gums: sore is common, severe recession is rarer
The internet swings between "it's fine" and "your teeth will fall out". Neither is true. A 2024 systematic review of the early nicotine-pouch studies found changes to the gum where the pouch sits to be common1 — and a 2026 review of 26 studies of Swedish snus found consistent evidence that gum recession happens mainly at the placement site: the same spot, every time, over a long time.2
The mechanism is simple. A pouch held against the gum causes local inflammation and, over time, inflammatory bone loss at that exact site, and the gum line quietly pulls back.2 That's why the damage is local, not spread across your mouth — and why where and how you use pouches changes your risk more than almost anything else.

§3The leathery white patch: is it scarring?
That toughened, pale patch where your pouch sits is real and very common: dentists found mouth lesions in 79% of pouch users aged 18–30 in a 2026 Swedish study.7 It's usually not a scar — it's tissue toughening, like skin where it's rubbed. Any patch that won't go, or changes, is worth showing a dentist.
§4The burn and the dry mouth
The sting is chemistry. Makers make pouches alkaline so nicotine crosses the gum faster; in one lab study they ranged from pH 6.9 to 10.1, while your mouth sits near neutral.3 If a pouch stings, a different product or a lower strength may feel gentler.
Dry mouth is one of the most reported side effects,1 though the cause isn't pinned down yet. The likeliest culprits are the dry pouch fibres and salts drawing moisture from the tissue they sit on. Saliva is part of your mouth's natural protection, so drink water through the day and mention it to your dentist.

§6The questions people actually search
Does snus cause gum recession?
It can, and there's consistent evidence for it — usually at the exact spot the pouch sits, in people who use the same placement heavily over a long time. Rotating where you put your pouch is one of the simplest ways to spread the load.
Do gums grow back after you stop?
Not on their own. Receded gum tissue doesn't typically regrow. But stopping or easing off usually halts the progression, and a dentist can talk you through options if recession is advanced.
Does snus cause white patches or scarring?
The pale, leathery patch is very common — tissue toughening, not a true scar. Unlike recession, it often improves once the spot gets a break, though for some people it takes a long time. Any patch that lingers or changes should be checked.
Why do my pouches burn or tingle?
Mostly the pH. Many pouches are made alkaline (up to about pH 10) to deliver nicotine faster, and your mouth sits close to neutral. Products differ a lot, so a different brand or a lower strength may sting less.
Why does snus make my mouth so dry?
Users report it a lot, but the cause isn't fully known. Most likely the pouch itself soaks up moisture and its salts dry the tissue it sits on. Sipping water and keeping up your oral hygiene genuinely helps.
Is snus worse than smoking?
Snus has its own oral issues, but on overall harm it's widely considered substantially lower-risk than cigarettes, because there's no smoke. Lower risk still isn't no risk.
Are my sore gums serious?
Soreness and mild irritation are common and often settle when you change placement. But anything that doesn't heal, or a white patch that won't go, is a reason to see a dentist — not to panic, just to get it checked.
§7What you can actually do
Mostly boring basics. No product replaces these — but we made one for the hardest of them.
Map your mouth.
A few taps about your habit and where your pouch sits. See your pouch footprint straight away, then map your full mouth and get a care plan.
Keep the ritual.
Lose the nicotine.
We use pouches too, and we got tired of knowing what the habit does and doing nothing about it. UVUKA is a soft, unsweetened botanical pastille you tuck into your upper lip like a pouch, for the moment after. Soft Nordic liquorice, ginger & chamomile, cardamom & vanilla. It doesn't reverse anything on this page — the basics above do that work. Judge it on how it feels.
Magnesium contributes to the maintenance of normal teeth. Zinc contributes to the normal function of the immune system. Nicotine-free food supplement — not a treatment.
