Does vaping ruin taste buds like smoking does? Many of our patients assume vaping is the safer choice because it produces vapor instead of smoke. When it comes to your sense of taste, vaping causes many of the same problems smoking does.
About 6.5% of U.S. adults used e-cigarettes in 2023, up from 4.5% in 2019, according to the CDC’s National Center for Health Statistics. Because vaping is still fairly new, long-term research is limited. What we know comes from a growing body of studies and from what we see in the patients who smoke and vape in our Grosse Pointe office.
What Is Vaper’s Tongue?
Vaping results in what is known as “vaper’s tongue.” Vaper’s tongue is a temporary dulling or loss of taste in people who vape. Flavors that used to taste strong seem faint, and some people can no longer taste their e-liquid at all. Common signs include:
- Food tastes bland or flat
- You can’t taste your usual vape flavor
- Your mouth feels dry or sticky
- Your tongue looks coated or feels swollen
- Bad breath that brushing doesn’t fix
Why Does Vaping Ruin Taste Buds?
Four things happen in your mouth and nose when you vape. Each one makes it harder for your taste buds to pick up flavor.
1. Vaping Dries Out Your Mouth
Propylene glycol, one of the main ingredients in vape juice, absorbs water. The American Association of Orthodontists points to this ingredient as the reason vapers get dry mouth. Saliva carries flavor to your taste buds, so less saliva means less flavor. Saliva also washes away food particles and neutralizes acids, which is why dry mouth raises your risk of cavities and gum disease.
2. Congestion Blocks Your Sense of Smell
Vaping can leave you congested, and a stuffy nose dulls flavor. According to Cleveland Clinic, your taste buds work with the smell receptors in your nose to create flavor. When those receptors can’t pick up aromas, food tastes flat.
3. E-Liquid Coats Your Tongue
Vape juice ingredients coat the tongue, so taste buds can’t receive flavor signals the way they normally would. Propylene glycol and vegetable glycerin, the base ingredients in most e-liquids, are the likely culprits. This happens with both nicotine and cannabis vapes.
4. Vaping Inflames Your Tongue
Even brief vaping or smoking can lead to inflammation on the tongue. Swollen taste buds send weaker signals to your brain, and ongoing inflammation contributes to other oral health problems.
Research on vaping and taste is still catching up. A 2024 study in the journal Appetite compared 213 young adults in New Zealand and found that vapers rated sweet smells as less pleasant than non-vapers did. Both groups detected faint tastes and smells about equally well, so vaping may affect how much you enjoy flavors more than whether you notice them.
Can Vaping Cause Long-Term Damage to Your Mouth?
Vaper’s tongue goes away once you stop. Other effects of vaping can last longer. Smoking or vaping affects your teeth, lips, and gums, and two areas stand out in the research.
Gum Disease
Researchers at NYU College of Dentistry followed 84 adults for six months and found that e-cigarette users had a distinct mix of mouth bacteria linked to gum disease. Clinical attachment loss, a key measure of worsening gum disease, got significantly worse only in the vaping group. The study was published in mBio in 2022. Early gum disease is reversible, so learn the signs of gingivitis and don’t skip your checkups.
Changes to Mouth Tissue and Oral Cancer Risk
A 2019 study in the International Journal of Molecular Sciences found that vaping can change tissue on a molecular level. Researchers found altered gene activity in the mouth cells of e-cigarette users, and many of those changes matched patterns seen in smokers. Some of the affected genes are tied to cancer development. If you vape, ask about screening for oral cancer at your next visit.
How Long Does Vaper’s Tongue Last?
For most people, taste comes back within one to two weeks after they stop vaping. That timeline matches how taste buds work. Cleveland Clinic explains that new taste receptor cells develop every week or two, about every 10 days on average.
If your taste hasn’t returned after a few weeks, see your dentist or doctor. The National Institute on Deafness and Other Communication Disorders lists upper respiratory infections, head injuries, chemical exposure, and poor dental hygiene among other causes of taste problems.
How to Get Your Sense of Taste Back
Stop Vaping
Stop vaping. That’s the best advice we can give you. A week or two away from vaping gives your taste cells time to replace themselves, and quitting protects your gums and mouth tissue too. For free support, visit Smokefree.gov or call the national quitline at 1-800-QUIT-NOW (1-800-784-8669).
Rinse With Saltwater
Gargling with saltwater can reduce swelling in your taste buds and clean your mouth while your sense of taste recovers. Stir half a teaspoon of salt into a cup of warm water, swish, and spit.
Drink More Water
Sipping water throughout the day offsets the drying effect of propylene glycol and keeps saliva flowing. Chewing sugar-free gum helps, too.
Keep Up With Your Oral Hygiene
Maintaining healthy oral hygiene routines can help as well. Brush twice a day, floss daily, and brush or scrape your tongue to remove the film e-liquid leaves behind. Regular cleanings and exams let us catch gum problems early.
The Final Verdict
Vaping can dull your sense of taste for as long as you keep doing it. E-liquid dries out your mouth, coats your tongue, and irritates the tissue in your mouth and nose. Research hasn’t shown that vaping permanently destroys taste buds, and most people get their sense of taste back within one to two weeks of quitting.
