Overview

What is oral cancer screening?

Oral cancer screening is a systematic visual and physical examination of the mouth, lips, tongue, throat, and surrounding tissues to identify abnormal changes that may indicate cancer or precancerous conditions. It takes only a few minutes and is performed as part of your routine dental exam.Oral cancer is among the most serious cancers affecting the head and neck — but when detected at an early stage, survival rates exceed 80%. The challenge is that early-stage oral cancer is often painless and invisible to the untreated eye. Regular professional screening is the most effective way to find it early, before symptoms develop and while treatment options are most effective.

Early Detection Saves Lives

When oral cancer is caught at Stage I or II, the five-year survival rate is dramatically better than at later stages. Regular screening — even when nothing feels wrong — is what allows us to find early changes before they progress.

Painless & Routine

Oral cancer screening is non-invasive and takes only two to three minutes. It’s performed as part of your regular dental exam — no additional appointment needed. There is no discomfort involved.

Beyond What Patients Can See

Early oral cancer often appears as subtle changes in tissue colour, texture, or thickness — changes that are invisible to patients and their families but identifiable to a trained dental professional. Regular exams are the only way to catch them reliably.
Who This Is For

Who should be screened for oral cancer?

All adult patients benefit from routine oral cancer screening at every dental exam. Certain risk factors increase the likelihood of developing oral cancer — patients with these factors should be especially diligent about regular checkups.

Tobacco Users

Tobacco — in all forms, including cigarettes, cigars, pipes, and smokeless tobacco — is the leading risk factor for oral cancer. Tobacco users have a significantly elevated lifetime risk and should receive screening at every dental and medical visit.

Heavy Alcohol Consumers

Heavy alcohol use is an independent risk factor for oral cancer — and the combination of tobacco and alcohol multiplies the risk substantially. Patients who regularly consume significant amounts of alcohol benefit most from consistent, frequent screening.

HPV-Positive Patients

HPV (Human Papillomavirus), particularly type 16, is a leading cause of oropharyngeal cancers. HPV-related oral cancers are increasing in prevalence and often affect younger patients without traditional risk factors. Screening is important regardless of age or lifestyle.

All Adults Over 40

Risk increases with age. All adults — regardless of tobacco or alcohol use — benefit from systematic oral cancer screening at every dental visit. The most common presentation offers no warning symptoms until the disease is advanced.
What To Expect

What happens during an oral cancer screening.

1

Visual Examination of the Mouth

Your dentist examines all accessible soft tissues: lips, cheeks, gums, floor of the mouth, the roof of the mouth, and all surfaces of the tongue — including the sides and back. We look for red patches (erythroplakia), white patches (leukoplakia), ulcers, and areas of unusual texture or asymmetry.

2

Neck & Lymph Node Palpation

We gently feel the lymph nodes in the neck and jaw area for swelling or firmness that may indicate a response to abnormal tissue. While this is a brief, gentle assessment, it adds meaningful clinical information — especially for patients with risk factors.

3

Tongue & Throat Inspection

The tongue is the most common site for intraoral cancer. We examine the top, sides, and underside of the tongue systematically. The soft palate and throat are also assessed visually where accessible. Patients are asked to say “ah” and move the tongue to the sides for full visualization.

4

Documentation of Findings

Any areas of concern are documented, measured, and photographed. Most findings are benign and resolve on their own — but we monitor them at a two-week to four-week follow-up to confirm resolution. Persistent lesions are referred to an appropriate specialist for biopsy.

5

Referral When Warranted

If we identify a lesion that warrants further investigation, we refer you promptly to an oral surgeon or specialist for biopsy and histological analysis. We facilitate this referral directly and follow up with you to confirm the next steps are in motion.
Honest Expectations

Benefits and realistic considerations.

What You Gain

  • Early detection of oral cancer — when treatment is most effective and outcomes are best
  • A comprehensive soft tissue exam that goes beyond what patients can see themselves
  • Peace of mind from a systematic clinical assessment at every dental visit
  • Prompt referral and clear next steps if anything requires further investigation

Things to Know

  • Screening identifies suspicious tissue — it does not diagnose cancer; biopsy is required for a definitive diagnosis
  • Many findings are benign — we monitor before referring to avoid unnecessary procedures
  • No screening method catches 100% of cases — lifestyle risk reduction remains the most important prevention
  • Oral cancer screening is included in your routine dental exam — there is no additional procedure cost
Preparation & Aftercare

Before, during, and after your screening.

Before Your Appointment

No special preparation is required — oral cancer screening is part of your routine exam. However, it’s helpful to mention any changes you’ve noticed: persistent mouth sores, areas of numbness, difficulty swallowing, or any lump or swelling you’ve been aware of. Don’t dismiss persistent changes as minor — that information is clinically valuable.

During the Screening

The screening is entirely non-invasive. Your dentist will gently move your tongue, ask you to open and close your mouth, and feel the neck area — all within a few minutes. If you have a strong gag reflex, let us know so we can take extra care when examining the back of the mouth and throat.

After the Screening

In most cases, the exam is clear and no follow-up is needed beyond your next scheduled visit. If we identify anything worth monitoring, we’ll schedule a brief follow-up in two to four weeks to see whether the finding has resolved. If we refer you for specialist assessment, we’ll provide the referral documentation and follow up to confirm receipt.

Why Tomken Dental

Why Mississauga patients rely on us for oral cancer screening.

Systematic, Not Incidental

Oral cancer screening at our clinic is a deliberate, structured part of every comprehensive exam — not a quick glance. We follow a consistent protocol covering all at-risk tissue sites so that no area is overlooked, regardless of how busy the appointment is.

Continuity That Catches Changes

When the same practice examines your mouth at every visit, we’re better positioned to notice changes over time. A lesion that appears between visits, or tissue that looks different from your last appointment, is far more likely to be caught by a team that knows your baseline.

Clear Referral Pathways

If a finding warrants specialist review, we refer promptly and follow through. Our team documents all findings carefully and communicates clearly with any specialists involved in your care — ensuring nothing falls through the cracks.
Common Questions

Oral cancer screening FAQ.

How often should I be screened for oral cancer?
Oral cancer screening is performed as part of every comprehensive dental exam — typically twice yearly for most patients. Patients with tobacco use, heavy alcohol consumption, or a history of HPV may benefit from more frequent exams. If you notice any changes between visits, contact us promptly rather than waiting.
No — oral cancer screening is entirely non-invasive and takes only two to three minutes. It involves a visual examination of soft tissues and gentle palpation of the neck and jaw. There is no discomfort for the vast majority of patients.
Most findings are benign — canker sores, irritation, or common tissue variations. We monitor anything unusual at a two-to-four-week follow-up to see if it resolves. If a finding persists or looks clinically suspicious, we refer you to an oral surgeon or specialist for biopsy. We facilitate this referral directly.
Yes — early oral cancer is frequently painless and may not be visible to the patient. This is why professional screening at every dental visit is so important. By the time symptoms such as pain, swelling, or difficulty swallowing appear, the disease is often at an advanced stage.
Oral cancer screening is typically included within the comprehensive exam, which is covered by most dental plans. There is generally no additional charge for the screening itself. We review your coverage at your appointment and let you know of any out-of-pocket costs before proceeding. Call (647) 692-6053 with questions.
