Does Vaping Cause Gum Disease?
New studies highlight how e-cigarettes alter oral health and may be contributing to gum disease. The latest research finds that e-cigarette users have a unique oral microbiome that is less healthy than nonsmokers but potentially healthier than cigarette smokers, and measures worsening gum disease over time.
Vaping hasn't been proven to cause gum disease, but the evidence is moving in that direction. A study from NYU College of Dentistry found that people who vape carry a mix of gum bacteria and inflammation signals that looks more like a smoker's mouth than a nonsmoker's, and gum health worsened in some vapers over six months. Vaping is not a safe alternative for your gums, and if you vape, your dentist should know.
What did the NYU study do?
Researchers followed 84 adults in three groups: cigarette smokers, e-cigarette users and people who had never smoked. Each person had two gum exams six months apart. At each visit, the team measured gum health, collected plaque from below the gumline to identify the bacteria living there, and measured immune proteins (cytokines) that drive inflammation. [1]
What did it find?
Everyone started with some gum disease. Smokers had the most severe disease, then vapers, then nonsmokers.
Vapers had their own bacterial mix. Their gum bacteria shared many features with smokers' and some with nonsmokers', but formed a distinct community, including higher levels of some bacteria associated with gum disease. [1]
Inflammation looked different. Vapers had different cytokine levels from the other groups, which the researchers interpreted as an altered immune response in the gums. [1]
Gum health worsened in some participants in every group over six months, including several vapers. According to NYU's press release, a companion paper found that loss of gum attachment to the teeth worsened significantly only in the vapers. [2]
What are the limits?
It was small. 84 people is enough to spot patterns, not to settle the question.
Six months is short. Gum disease develops over years.
It is observational. People who vape may differ from nonsmokers in other ways, and some vapers are former smokers.
Vaping products vary widely in nicotine and other ingredients.
Why might vaping affect your gums?
Nicotine narrows blood vessels and can affect how gums respond to infection and heal. E-cigarette aerosol also contains chemicals and flavorings that change the environment of the mouth. The NYU work suggests these changes favor bacteria linked to gum disease. Researchers are still working out the details.
What should you do if you vape?
Tell your dentist. It changes what we look for.
Watch for bleeding gums, recession, bad breath or loose teeth.
Keep up brushing, cleaning between your teeth and regular dental visits.
Consider quitting. For help, talk with your physician or call 1-800-QUIT-NOW, the free national quitline.
The National Institute of Dental and Craniofacial Research lists e-cigarettes among the tobacco products that raise oral cancer risk, so an oral cancer exam matters too. [3]

April Is Oral Cancer Awareness Month: What to Know
Every hour, 24-hours-a-day, 365-days-a-year, someone dies of oral or oropharyngeal cancer (cancer of the mouth and upper throat). Yet, if oral cancer is detected and treated early, treatment-related health problems are reduced and survival rates may increase.
Each April, the Oral Cancer Foundation and dental organizations use Oral Cancer Awareness Month to encourage people to learn the early signs of mouth and throat cancer and to have an oral cancer exam. Most mouth sores and patches are harmless, but any change that lasts more than two weeks should be examined by a dentist or physician. Finding these cancers early generally makes treatment simpler.
How common is oral cancer?
The American Cancer Society estimates that about 60,480 people in the United States will be diagnosed with cancer of the mouth or oropharynx (the part of the throat behind the mouth, including the tonsils and base of the tongue) in 2026, and about 13,150 will die of these cancers. [1]
Who is at higher risk?
Tobacco in any form, including cigarettes, cigars, pipes, chewing tobacco and e-cigarettes
Heavy alcohol use, especially combined with tobacco
HPV infection, which causes many cancers of the oropharynx
Age, with most cases in people over 40
Sun exposure, for cancer of the lip [2]
HPV-related throat cancer often occurs in people who have never smoked. Most HPV infections clear on their own, and only a small share of people go on to develop cancer. The HPV vaccine protects against the virus types most often linked to these cancers. Ask your physician whether it is right for you or your children.
What does an oral cancer exam involve?
An oral cancer exam is quick and painless. The dentist or hygienist looks at and feels your lips, cheeks, tongue, floor and roof of the mouth, and throat, and feels the neck and under the jaw for lumps. [2] If something looks unusual, the next step may be a recheck in two weeks or a biopsy, depending on what is found. Only a biopsy can confirm or rule out cancer. Read about how oral cancer screening works at our office.
Which changes should you have checked?
See a dentist or physician if any of these last more than two weeks:
A sore or ulcer that doesn't heal
A red or white patch
A lump or thickening in the mouth or on the neck
Ongoing sore throat, hoarseness or trouble swallowing
Numbness of the tongue or lip
Our post on the warning signs of mouth cancer explains each one and how to check your own mouth.
