When people think about cancer, the mouth often isn't the first place that comes to mind. Yet each year, tens of thousands of individuals in the U.S. are diagnosed with oral cancer — a condition that can affect the lips, tongue, cheeks, throat, and other parts of the mouth.
Oral cancer, often overlooked, can be life-threatening if not detected early. However, armed with the right knowledge and empowered by regular dental care, it's also one of the most preventable and treatable forms of cancer. We spoke with Dr. Marielaina Perrone, DDS, a leading cosmetic and general dentist in Henderson, Nevada, to shed light on the signs, risks, and proactive steps you can take to stay safe.
“Early detection truly saves lives,” says Dr. Perrone. “Oral cancer doesn't always cause pain or noticeable symptoms at first, so routine screenings during dental visits are essential.”
What Is Oral Cancer?
Oral cancer refers to cancers that develop in the mouth or throat tissues. This includes:
Lips
Tongue
Cheeks
Gums
The floor of the mouth
Roof of the mouth
Oropharynx (back of the throat, including tonsils)
Most oral cancers are classified as squamous cell carcinomas, which originate in the flat cells lining the mouth and throat.
According to the Oral Cancer Foundation, nearly 54,000 Americans are diagnosed with oral or oropharyngeal cancer annually, and the disease causes more than 9,000 deaths each year. This means that every hour, someone in the United States dies from oral cancer. These numbers are not just statistics, but they represent real people-mothers, fathers, young adults-whose outcomes could improve dramatically with early intervention.
“These aren't just statistics,” Dr. Perrone reminds us. “They represent patients—mothers, fathers, young adults—whose outcomes could improve dramatically with early intervention.”
Major Risk Factors
While oral cancer can affect anyone, certain factors can increase your risk:
Tobacco Use: Cigarettes, cigars, pipes, and smokeless tobacco products are among the most significant risk factors.
Alcohol Consumption: Excessive drinking, especially when combined with tobacco use, increases risk.
HPV Infection: The human papillomavirus (particularly HPV-16) is a rising cause of oropharyngeal cancers.
Sun Exposure: Prolonged sun exposure can lead to lip cancer.
Age: Most cases are diagnosed in people over 40, though HPV-related cancers are increasingly affecting younger adults.
“HPV-related oral cancers are on the rise, especially among people who don't smoke or drink,” Dr. Perrone explains. “This underscores the importance of universal screening—regardless of lifestyle.”
Warning Signs to Watch For
One of the challenges with oral cancer is that early symptoms are often subtle or painless. That's why regular dental checkups are vital in catching issues before they advance.
Some common signs include:
Persistent mouth sores that don't heal within two weeks
Red or white patches inside the mouth
Lumps, bumps, or thickened areas in the mouth or neck
Pain, numbness, or tenderness in the mouth, face, or neck
Difficulty swallowing or a sensation of something stuck in the throat
Hoarseness or voice changes
“If you notice something unusual in your mouth—especially if it lingers—don't ignore it,” says Dr. Perrone. “The sooner we investigate, the better the outcome.”
The Role of Oral Cancer Screenings
Regular dental visits aren't just about clean teeth—they're a first line of defense against oral cancer. Dentists like Dr. Perrone play a crucial role in performing a visual and physical screening of the mouth, lips, throat, and lymph nodes for abnormal signs during a routine exam, providing you with the reassurance and support you need.
Advanced practices also use technology like VELscope®, a handheld light that highlights tissue changes invisible to the naked eye.
“I include oral cancer screenings in every check-up,” Dr. Perrone shares. “It's quick, painless, and potentially life-saving. Patients often don't even realize we're doing it.”
Tips for Prevention and Early Detection
While no cancer is entirely preventable, there are steps you can take to reduce your risk and stay informed:
✅ Avoid tobacco in all forms
✅ Limit alcohol intake
✅ Protect your lips with SPF lip balm
✅ Get vaccinated for HPV
✅ Conduct monthly self-exams in the mirror
✅ Visit your dentist regularly for exams and cleanings
“Oral cancer isn't just a concern for smokers anymore,” Dr. Perrone cautions. “It's a conversation every dental and medical provider should be having with their patients.”
Life After Oral Cancer: The Dental Connection
Surviving oral cancer often involves a long journey of recovery, including reconstructive procedures, rehabilitation of speech or chewing, and emotional healing. Dentists play a key role in supporting patients during and after cancer treatment.
“We help survivors regain function and confidence,” Dr. Perrone says. “That might include managing dry mouth, fitting prosthetics, or restoring smiles affected by surgery or radiation.”
The psychological impact of oral cancer can be profound. That's why comprehensive care often includes referrals to nutritionists, speech therapists, counselors, and support networks.
Final Thought: A Smile Worth Protecting
Oral cancer may not always be visible or painful at first, but its consequences can be life-altering. With routine screenings, public awareness, and lifestyle choices, we can reduce risks and catch potential problems early.
“Your mouth is one of the most important indicators of overall health,” says Dr. Marielaina Perrone. “By staying informed, being proactive, and partnering with your dental provider, you can protect your health—and your smile—for years to come.”
