Understanding Oral Cancer Screenings: What Happens at Your Exam?

When it comes to protecting your oral health, regular dental exams do more than just keep your teeth clean—they can also save your life. One of the most critical yet often overlooked components of a dental visit is the oral cancer screening. Oral cancer affects tens of thousands of Americans each year, and early detection is one of the best ways to improve outcomes.

At Dentist of Cerritos, we take oral cancer awareness seriously. In honor of Oral Cancer Awareness Month this April, we’re shedding light on what an oral cancer screening involves, why it matters, and what to expect during your exam.

Why Oral Cancer Screenings Matter

Oral cancer can affect any part of the mouth, including the lips, tongue, cheeks, floor of the mouth, hard and soft palates, sinuses, and throat. Unfortunately, it’s often not detected until it reaches a more advanced stage—which makes routine screenings during dental visits so important.

The Alarming Statistics

• Over 54,000 people in the U.S. are diagnosed with oral or oropharyngeal cancer each year.
• Oral cancer causes over 11,500 deaths annually.
• The 5-year survival rate significantly improves when oral cancer is caught in its early stages—up to 84% for localized cancers.

Routine dental exams are your first line of defense. Dentists are trained to detect early warning signs that patients may not notice, especially since early-stage oral cancer is often painless and symptom-free.

Who Is Most at Risk?

Oral cancer doesn’t discriminate, but certain behaviors and conditions can significantly increase your risk. These include:

• Tobacco use: Smoking or chewing tobacco is the leading cause of oral cancer.
• Excessive alcohol consumption: Heavy drinkers have a higher risk, especially when combined with tobacco use.
• HPV infection: Human papillomavirus, particularly HPV-16, has been linked to oropharyngeal cancers.
• Age: Most cases are diagnosed in people over age 40.
• Sun exposure: Increases the risk of lip cancer.
• Poor nutrition and a weakened immune system can also contribute to elevated risk levels.

If you fall into one or more of these categories, regular screenings are especially important for you.

What Happens During an Oral Cancer Screening?

An oral cancer screening is a quick, non-invasive process that can be completed during your routine dental checkup. It involves both a visual and physical examination of your mouth and surrounding areas.

Step-by-Step: What to Expect

• Visual Examination
  Your dentist will begin by checking your mouth for any abnormalities. They’ll examine your:

• Lips and cheeks
• Tongue (top, sides, and underneath)
• Roof and floor of your mouth
• Gums
• Back of the throat
• Tonsil area

They’ll look for red or white patches, lumps, sores that don’t heal, or any changes in texture or coloration.

• Physical Examination
  Next, your dentist will gently palpate (feel) your jaw, neck, and lymph nodes for any swelling, lumps, or tenderness. They’ll also feel under your chin and along your jawline.
• Use of Special Tools
  Some screenings may involve the use of specialized lights or dyes that help highlight abnormal cells. For instance:

• VELscope: A blue light that reveals tissue changes not visible to the naked eye.
• Toluidine blue dye: A dye that can temporarily stain suspicious areas to make them easier to identify.

• Patient Discussion
  Your dentist may ask about any symptoms you’ve noticed recently, such as:

• Persistent sore throat
• Hoarseness
• Difficulty swallowing or chewing
• Numbness in the mouth or face
• A sore or growth that doesn’t heal

If anything suspicious is found, your dentist will explain the next steps, which may include further testing or a referral to a specialist for a biopsy.

How Often Should You Get an Oral Cancer Screening?

Most patients should receive an oral cancer screening at least once a year during their regular dental exam. However, if you have higher risk factors, your dentist may recommend screenings more frequently.

The best part? These screenings are usually included in your regular dental checkup, meaning no extra appointment is necessary.

What Happens If Your Dentist Finds Something?

Finding a suspicious area during a screening doesn’t mean you have cancer. Many non-cancerous conditions can mimic the appearance of oral cancer. If anything unusual is detected, your dentist may:

• Monitor the area and ask you to return in a few weeks.
• Refer you to an oral surgeon or ENT specialist.
• Recommend a biopsy to determine whether abnormal cells are present.

Early detection makes a significant difference in the outcome of oral cancer. The sooner treatment begins, the better the chances of a full recovery.

Tips to Lower Your Risk of Oral Cancer

While not all risk factors can be avoided, there are steps you can take to lower your chances of developing oral cancer:

• Stop smoking or using tobacco products.
• Limit or avoid alcohol consumption.
• Protect your lips with SPF lip balm when outdoors.
• Maintain a healthy diet rich in fruits and vegetables.
• Practice good oral hygiene and see your dentist regularly.
• Get vaccinated for HPV, especially if you’re under age 45.

Being proactive about your oral health isn’t just about your teeth and gums—it’s about your whole body wellness.
