Does vaping cause gum disease?

What gum disease actually is

Gum disease has two main stages. Gingivitis is the early, reversible stage. Gums become red, swollen and bleed when brushing. Periodontitis is the advanced stage. The infection spreads to the bone supporting your teeth. If untreated, it leads to gum recession, loose teeth and eventually tooth loss.

Gum disease affects around 45% of UK adults to some degree. It is one of the most common chronic conditions in the country and one of the leading causes of tooth loss in adults.

What the research shows

Multiple studies have now looked at gum disease rates in vapers. The findings are reasonably consistent.

A 2020 study in the journal iScience found that 43% of vapers had gum disease or oral infections, compared to 73% of smokers and 28% of people who neither smoked nor vaped.

A 2024 systematic review found that vapers had a greater risk of periodontal disease than non-smokers but a lower risk than smokers. A separate study from NYU College of Dentistry in 2022 found that vapers had a distinct oral microbiome compared to both smokers and non-users, and that this altered mix of bacteria triggered different immune responses in the mouth.

The honest summary: vaping carries real gum disease risk. Less than smoking, more than nothing.

How vaping affects your gums

The vaping vs smoking comparison

For oral health specifically, vaping is the lesser of two evils when compared with smoking, but the gap is not as big as it is for some other health markers.

Both are worse than not using either, but the difference between vaping and smoking is meaningful. For former smokers, switching to vaping is a step in the right direction for oral health.

What dentists are seeing

Common patterns dentists report in vaper patients:

• Gums that look healthy on the surface but show deep pocketing on examination. The bleeding-suppression effect of nicotine hides early signs.
• Higher plaque accumulation, particularly around brackets, between teeth and at the gum line.
• Slower healing after dental procedures like extractions, gum surgery and deep cleaning.
• Increased gum recession in younger patients who would not normally be expected to show it.
• Bone loss visible on X-rays that suggests longer-standing periodontal damage than expected for the patient's age.

How to protect your gums while still vaping

Quitting nicotine entirely is the best move for gum health. If you cannot or do not want to, the steps below significantly reduce the risk.

1. Brush twice a day with proper technique

   Use a soft-bristled brush at a 45-degree angle to the gum line. Two minutes minimum. Use fluoride toothpaste. The single biggest factor in preventing gum disease in anyone, vaper or not.

2. Floss or use interdental brushes daily

   Removes plaque from between teeth where your toothbrush cannot reach. This is where most gum disease starts.

3. Drink plenty of water

   Combats the dry mouth that vaping causes. Helps saliva flow, which is your mouth's natural defence.

4. See a dental hygienist every 6 months

   Professional cleaning removes built-up plaque and tartar that home brushing cannot. Particularly important for vapers because of the higher baseline risk.

5. Use an alcohol-free mouthwash

   Alcohol-based mouthwashes dry the mouth further. Look for ones with chlorhexidine or cetylpyridinium chloride, which target the bacteria that cause gum disease.

6. Lower your nicotine strength

   Less nicotine means less vasoconstriction and better blood flow to the gums. Most vapers can step down 5mg or 10mg without significant cravings.

7. Tell your dentist you vape

   They will check more carefully for early signs of gum disease and may recommend more frequent visits. Not for moral judgement, just for better care.
