Oral Cancer Exam Waterloo, ON
At Trillium Dental Centre, each and every one of our patients, regardless of their age, undergo a thorough oral cancer exam at their regular checkups and cleanings. Our diligent dental team are educated to the signs and symptoms that may be possible signs or oral cancer.
According to research conducted by the American Cancer society, more than 30,000 cases of oral cancer are diagnosed each year. More than 7,000 of these cases result in the death of the patient. The good news is that oral cancer can easily be diagnosed with an annual oral cancer exam, and effectively treated when caught in its earliest stages.
Oral cancer is a pathologic process which begins with an asymptomatic stage during which the usual cancer signs may not be readily noticeable. This makes the oral cancer examinations performed by the dentist critically important. Oral cancers can be of varied histologic types such as teratoma, adenocarcinoma and melanoma. The most common type of oral cancer is the malignant squamous cell carcinoma. This oral cancer type usually originates in lip and mouth tissues.
There are many different places in the oral cavity and maxillofacial region in which oral cancers commonly occur, including:
- Lips
- Mouth
- Tongue
- Salivary Glands
- Oropharyngeal Region (throat)
- Gums
- Face
Reasons for Oral Cancer Examinations
It is important to note that around 75 percent of oral cancers are linked with modifiable behaviors such as smoking, tobacco use and excessive alcohol consumption. Your dentist can provide literature and education on making lifestyle changes and smoking cessation.
When oral cancer is diagnosed in its earliest stages, treatment is generally very effective. Any noticeable abnormalities in the tongue, gums, mouth or surrounding area should be evaluated by a health professional as quickly as possible. During the oral cancer exam, the dentist and dental hygienist will be scrutinizing the maxillofacial and oral regions carefully for signs of pathologic changes.
The following signs will be investigated during a routine oral cancer exam:
- Red patches and sores – Red patches on the floor of the mouth, the front and sides of the tongue, white or pink patches which fail to heal and slow healing sores that bleed easily can be indicative of pathologic (cancerous) changes.
- Leukoplakia – This is a hardened white or gray, slightly raised lesion that can appear anywhere inside the mouth. Leukoplakia can be cancerous, or may become cancerous if treatment is not sought.
- Lumps – Soreness, lumps or the general thickening of tissue anywhere in the throat or mouth can signal pathological problems.
Oral Cancer Exams, Diagnosis and Treatment
The oral cancer examination is a quick, comfort-focused process. During the visual part of the examination, the dentist will look for abnormality and feel the face, glands and neck for unusual bumps. Lasers which can highlight pathologic changes are also a wonderful tool for oral cancer checks. The laser can “look” below the surface for abnormal signs and lesions which would be invisible to the naked eye.
If abnormalities, lesions, leukoplakia or lumps are apparent, the dentist will implement a diagnostic impression and treatment plan. In the event that the initial treatment plan is ineffective, a biopsy of the area will be performed. The biopsy includes a clinical evaluation which will identify the precise stage and grade of the oral lesion.
Oral cancer is deemed to be present when the basement membrane of the epithelium has been broken. Malignant types of cancer can readily spread to other places in the oral and maxillofacial regions, posing additional secondary threats. Treatment methods vary according to the precise diagnosis, but may include excision, radiation therapy and chemotherapy.
During bi-annual check-ups, the dentist and hygienist will thoroughly look for changes and lesions in the mouth, but a dedicated comprehensive oral cancer screening should be performed at least once each year.
Our periodontics in Waterloo also helps us spot early changes in your gums that could point to more serious oral health issues, including signs that shouldn’t be ignored.
If you have any questions or concerns about oral cancer, please call our office to discuss it with our team.

What to Expect During an Oral Cancer Screening
An oral cancer screening is a focused visual and tactile exam of the head, neck, and oral cavity to detect early signs of oral or oropharyngeal cancer. It's a standard part of every comprehensive dental exam, and it takes just a few minutes — but those few minutes can identify lesions early, when treatment outcomes are significantly better.
The exam includes inspection of the lips, the inside of the cheeks, the floor of the mouth, the tongue (all sides — including underneath, which patients often don't look at), the palate (hard and soft), the tonsillar area, and the back of the throat. We also palpate the neck for lymph nodes and the floor of the mouth for any unusual firmness.
If we find anything that warrants attention — an asymmetric lesion, an area that doesn't look or feel normal, a sore that hasn't healed in two weeks — we discuss it with you and decide on next steps. Most findings turn out to be benign (cheek bites, irritations, common variations). For suspicious findings, we may recommend monitoring for two weeks, taking digital photos for comparison, or referring you to an oral pathologist or oral and maxillofacial surgeon for biopsy.
Who Should Have Regular Screenings
Oral cancer screening is recommended at every routine dental exam (typically every 6 months) for all adults. Some patients are at elevated risk and benefit from particular attention or more frequent screening:
- Current or former tobacco users (smoking or chewing)
- Heavy alcohol use (more than 3 drinks per day)
- HPV exposure — relevant for oropharyngeal cancers, increasingly seen in patients without traditional risk factors
- Sun exposure (relevant for lip cancers)
- Personal history of oral cancer or precancerous lesions
- Age over 40 (incidence rises with age)
- Patients with chronic immune suppression
Self-checks between appointments help. Look at your mouth in the mirror once a month — anything you notice (a sore that doesn't heal in two weeks, a lump in the neck, persistent hoarseness, difficulty swallowing) is worth getting checked sooner rather than later.
What Happens If We Find Something Suspicious
Most findings during oral cancer screening are not cancer. Cheek bites, ulcers from minor irritants, common variations of normal anatomy, and benign lesions are far more common than malignancy. Our first step is usually conservative: if a lesion looks low-suspicion, we take photographs, document the location and appearance, and re-check in two weeks. Many lesions resolve on their own in that window.
If a lesion persists, looks higher-risk, or has features that warrant immediate evaluation, we refer to an oral pathologist or oral and maxillofacial surgeon for biopsy. A biopsy is the only way to confirm what a tissue is — visual exam can suggest, but biopsy answers. The procedure is straightforward (usually done under local anaesthetic), and pathology results typically come back within one to two weeks.
From the biopsy result, treatment paths are charted in consultation with the appropriate specialists (oral and maxillofacial surgeons, ENT, oncology, radiation oncology). Most early-stage oral cancers are highly treatable when caught early — which is the whole point of routine screening.
Cost and Insurance Coverage
Oral cancer screening is included in a comprehensive or recall dental exam — it's not billed separately. Some additional adjunctive screening technologies (e.g., VELscope tissue fluorescence) are available at certain offices for an additional fee and may be discussed when appropriate. We follow the current Ontario Dental Association (ODA) Suggested Fee Guide.
Standard exams (including the cancer screening portion) are generally covered under basic services on extended dental insurance plans, typically at 80-100% reimbursement subject to your annual maximum and exam frequency limits (usually one comprehensive exam per year, recalls every 6 or 9 months). The federal Canadian Dental Care Plan (CDCP) covers routine dental exams for eligible patients.
Oral Cancer Screening — Frequently Asked Questions
How often should I be screened?
At every routine dental exam — typically every 6 months. Patients at elevated risk may benefit from more frequent attention; we discuss this individually.
Does the screening detect throat cancer?
Visual screening reaches the back of the oral cavity and the visible tonsillar area, but not deeper into the throat or larynx. For symptoms specific to the throat (persistent hoarseness, difficulty swallowing, neck masses), referral to an ENT for fiberoptic examination is appropriate.
Are there better screening technologies?
Several adjunctive tools (tissue fluorescence devices, brush biopsies, mouth-rinse cytology) supplement traditional visual screening. The evidence for their additional benefit over a thorough visual exam by a trained provider is mixed, and they generally aren't currently recommended as routine for all patients. We discuss if a specific adjunctive test might be useful for your situation.
Should I be worried about HPV-related oral cancer?
HPV-related oropharyngeal cancer has been rising and affects patients without traditional risk factors (non-smokers, moderate drinkers). The HPV vaccine prevents the strains most commonly associated with this cancer. We can discuss your risk and vaccination options.
What does a suspicious lesion look like?
Lesions that warrant attention often share features: persistent (more than two weeks), asymmetric, red or white patches, raised or thickened areas, sores that don't heal, or unusual firmness on palpation. Not every lesion with these features is cancer, but they're the features that trigger a closer look. Anything you notice that doesn't resolve in two weeks is worth showing us.
