The Importance of HPV Vaccination for Your Oral Health

Did you know that HPV — a widespread sexually transmitted infection — can lead to serious health issues, including oral cancer? It’s not a connection most people expect to hear about at the dentist, but oral health professionals have an important role to play here. The encouraging news is that there are effective preventive measures, and HPV vaccination is chief among them. Here’s what every patient should know about HPV, its link to oral health, and why vaccination matters.

What is HPV?

Human papillomavirus, commonly known as HPV, isn’t a single virus — it’s a group of more than 100 different types. More than 40 of those types are transmitted through sexual contact and can cause infections in the genital areas of both women and men. Importantly for our purposes, some types can also infect parts of the mouth and throat.

HPV is remarkably common. According to the Canadian government, about 70% of sexually active men and women will have a sexually transmitted HPV infection at some point in their lives. Most infections cause no symptoms at all, which means most people never know they’ve been infected — and that makes it very difficult to know exactly when or how the virus spreads. While most high-risk HPV infections resolve on their own within a few years, some persist, and persistent infections can ultimately lead to cancer.

HPV and your oral health

The link between HPV and mouth and throat cancer is significant. Research indicates that approximately 25% to 35% of mouth and throat cancers in Canada are related to oral HPV infection. Men are affected disproportionately: in 2012, the incidence rate of HPV-associated oropharyngeal cancer — cancer affecting the back of the throat — was more than 4.5 times higher in males than females.

Canada has made real progress against cervical cancer through screening and vaccination, but the picture for HPV-related mouth and throat cancers is different. These cancers often appear in middle age, decades after infection, which means the protective impact of vaccination unfolds gradually over time.

Symptoms to watch for

Many people with HPV have no symptoms of the infection at all. When signs of oral or oropharyngeal cancer do appear, they can include:

• A sore on the lip or inside the mouth that doesn’t heal
• Lumps or thickening in the lips, mouth, or cheek
• White or red patches on the gums, tongue, tonsil, or lining of the mouth
• A persistent sore throat, or the sensation of something stuck in the throat
• Difficulty chewing or swallowing
• Difficulty moving the jaw or tongue

If any of these persist, don’t wait — have them examined promptly. Most turn out to be something minor, but the ones that aren’t are far more treatable when caught early.

How HPV vaccination helps prevent cancer

Vaccination is one of the most powerful preventive tools we have against HPV-related disease:

• It prevents infection. Vaccination protects against several high-risk HPV strains, dramatically reducing the risk of infection in the first place.
• It prevents cancer. HPV is a major cause of cervical, anal, penile, and oropharyngeal cancers. Vaccination significantly lowers the risk of developing these cancers in both males and females.
• It protects the community. Widespread vaccination contributes to herd immunity, protecting those who can’t be vaccinated and reducing the virus’s spread.
• Protection is long-lasting. HPV vaccines offer durable protection against the targeted types, potentially providing lifelong immunity.
• Timing matters. Vaccination is most effective when given during adolescence or early adulthood — ideally before becoming sexually active and before potential exposure. Getting vaccinated before age 25 can substantially reduce the risk of HPV-related oral health issues and oral cancers later in life.

The Canadian Cancer Society recommends that Canadians get vaccinated to reduce their risk of HPV-related cancer. Your family doctor is the best person to talk to about vaccination for yourself or your children.

Where your dental team fits in

Because HPV-related throat cancers often develop without obvious early symptoms, regular screening is a crucial safety net — and it’s one of the quiet benefits of routine dental visits. At our office, an oral cancer screening is part of your regular exam: we check the soft tissues of your mouth, tongue, and throat for anything unusual. It takes only minutes, it’s completely painless, and it means changes get noticed early, when treatment is most effective.

Stay informed, stay screened

Understanding the link between HPV and oral cancer — and acting on it through vaccination and regular screening — is one of the most meaningful things you can do for your long-term health. Talk to your doctor about HPV vaccination for your family, and keep up with your dental check-ups so screening happens automatically.
