Does vaping damage teeth?

How vaping affects your teeth

Tooth damage from vaping mostly comes from three things at once: less saliva, more cavity-causing bacteria, and direct erosion from acidic ingredients. They reinforce each other, which is why the damage can build faster than expected.

What UK dentists are seeing

Dental surgeon Smita Mehra recently told the Daily Mail she has seen a worrying rise in young UK vapers turning up with cavities that used to be rare in patients under 30. Action on Smoking and Health estimates around 5.5 million UK adults vape, around 10% of the population, with the rate higher in younger groups.

The decay pattern dentists are reporting in vapers is unusual. It tends to appear on the smooth surfaces of teeth and on the biting tips of front teeth, which are normally easier to clean and less prone to cavities.

Dentists are also seeing:

• Faster enamel wear in vapers compared to non-vapers of similar age, especially with acidic or sweet flavours.
• More frequent cavities at the gum line, where reduced saliva flow lets plaque build up faster.
• Increased tooth sensitivity, particularly to cold and sweet, as enamel thins.
• Discolouration on front teeth, from nicotine residue rather than tar staining.

Vaping versus smoking for teeth

Honest comparison time. Vaping is less damaging to teeth than smoking, but it is not harmless.

Vaping introduces a new problem smoking did not have: a sticky, sweet aerosol coating teeth in locations where decay used to be rare. Switching from smoking to vaping reduces some risks but adds this one.

How to protect your teeth while vaping

1. Brush twice a day with fluoride toothpaste

   Standard advice, but it does the heavy lifting. Fluoride helps remineralise early enamel damage. Use a soft-bristled brush.

2. Floss daily

   Removes plaque from between teeth where your toothbrush cannot reach. Particularly important for vapers because of the higher overall cavity risk.

3. Rinse with water after vaping

   Removes the sticky aerosol from your teeth before it can sit and feed bacteria. Simple, free, makes a real difference.

4. Stay hydrated

   Water keeps saliva flowing, which is your teeth's natural defence. The more you vape, the more important this becomes.

5. Use sugar-free gum with xylitol

   Stimulates saliva flow and xylitol actively reduces cavity-causing bacteria. Particularly useful after vaping if you cannot brush.

6. Consider prescription fluoride toothpaste

   Some dentists recommend stronger fluoride toothpaste for higher-risk patients. Available from your dentist if needed.

7. Avoid acidic and very sweet flavours where you can

   Tobacco and menthol flavours tend to be less damaging than sweet fruit or dessert flavours. Worth considering if your teeth are vulnerable.

8. See a dentist every 6 months

   Vapers are higher-risk patients. More frequent check-ups catch problems earlier when they are still cheap and easy to fix.
