Oral cancer may account for a modest share of overall cancer diagnoses, but its impact on individuals and families can be profound. Because early-stage lesions are often painless and easy to overlook, routine screening during dental visits is one of the most effective ways to catch problems before they progress. A screening is a quick, preventive step that fits naturally into a comprehensive exam and can substantially improve outcomes when abnormalities are found early.
Screenings are not designed to alarm patients; instead, they are proactive checks that protect long-term oral and overall health. The goal is to identify suspicious tissue changes, persistent sores, or other warning signs that warrant closer evaluation. When detected early, many oral cancers can be treated more effectively and with fewer long-term consequences to appearance and function.
By making oral cancer screening a routine part of dental care, clinicians create an additional safety net for patients. Regular exams complement self-awareness—if a patient notices anything unusual between visits, the combination of professional screening and timely reporting helps ensure prompt follow-up and, when needed, swift referral to a specialist.
Oral cancers can originate in several areas of the mouth and throat. Dentists carefully examine the tongue, the floor and roof of the mouth, the gums, inner cheeks, lips, and the oropharynx (including the tonsils and back of the throat). Each of these sites can present slightly different warning signs, so a complete visual and tactile exam is important for a thorough assessment.
Typical findings that prompt further evaluation include persistent white or red patches, lumps or thickened areas, unexplained ulcers that do not heal within two weeks, and any new or changing growths. Some lesions may be subtle—slightly raised, rough-textured, or discolored—so careful inspection under good lighting is a key part of the screening process.
Because lesions can be hidden or develop in areas that patients don’t easily see, the dentist’s trained eye and hands often reveal concerns that might otherwise go unnoticed. When warranted, clinicians may document findings with high-resolution intraoral images or recommend adjunctive screening tools to help determine whether a biopsy or specialist evaluation is needed.
Although anyone can develop oral cancer, certain risk factors increase the likelihood of occurrence. Tobacco use and heavy alcohol consumption remain the most significant contributors, and when combined they amplify overall risk. In addition, long-term exposure to ultraviolet light can raise the chance of cancers on the lips, while past radiation to the head and neck may also play a role.
In recent years, infection with certain strains of human papillomavirus (HPV) has been linked to a growing share of oropharyngeal cancers, particularly in younger adults who do not have the traditional risk factors of tobacco or alcohol use. This shift highlights why screening remains relevant across age groups and lifestyles—clinicians can identify signs that warrant further testing regardless of a patient’s perceived risk.
Other contributors include chronic irritation, poor nutrition, and conditions like gastroesophageal reflux disease that expose oral tissues to stomach acids. Because many risk factors are cumulative, open conversations about lifestyle, medical history, and changes in oral health help the dental team tailor screening frequency and follow-up recommendations.
A typical screening is efficient, noninvasive, and comfortable. It begins with a review of your medical and dental history and a brief discussion about any new symptoms—such as persistent soreness, difficulty swallowing, or changes in voice. This context helps the clinician focus the exam and better interpret what they observe during the visual and tactile assessment.
The dentist will then examine the mouth and surrounding areas under bright light, systematically checking the lips, tongue (top, bottom, and sides), floor and roof of the mouth, cheeks, and throat. They will also palpate the neck and jaw regions to feel for enlarged or firm lymph nodes, since changes there can sometimes signal a deeper issue.
When something appears suspicious, the next steps are determined case by case. The dentist may take photographs, use adjunctive devices that enhance visualization, or recommend a biopsy or referral to an oral medicine specialist or ENT for definitive diagnosis. Importantly, most screenings find benign conditions—yet the screening is valuable because it enables early detection when treatment options are most effective.
Patients should be aware of persistent signs that merit professional attention: sores that fail to heal within two weeks, unexplained lumps, red or white patches, persistent hoarseness, difficulty chewing or swallowing, and any new numbness or pain in the mouth or face. Not every symptom indicates cancer, but timely evaluation reduces uncertainty and opens the door to early treatment when needed.
If a screening identifies an area of concern, the dental team will explain the findings clearly and recommend an appropriate plan. That plan may include monitoring the area for change, scheduling a biopsy to obtain tissue for pathology, or arranging prompt referral to a specialist. Throughout the process, communication focuses on clarity, compassion, and practical next steps.
At Silk Dental Delray Beach (formerly Marc Bilodeau DMD), we emphasize education and partnership: we explain what we see, why we recommend a particular follow-up, and what patients can expect from testing or specialist care. Our aim is to remove anxiety through information and to coordinate care efficiently so patients move forward with confidence and timely support.
Prompt detection of oral cancer begins with routine screening and informed patients. If you would like to learn more about how oral cancer screening is performed or how often you should be evaluated, please contact us for more information.
