3. Unexplained Bleeding in the Mouth
Bleeding that is not caused by injury or brushing may signal something more serious. While occasional bleeding from gums can occur due to poor oral hygiene or gum disease, persistent or unexplained bleeding should be checked.
What to do: If the bleeding is recurrent and not linked to brushing or trauma, talk to your dentist or doctor for further evaluation.
4. Lumps, Thickened Areas, or Rough Patches
According to the CDC, the presence of a lump or thickening in any part of the mouth, tongue, or throat should be taken seriously. These may be painless at first but can grow over time. Uneven or rough areas on the gums, cheeks, or under the tongue can also be a sign of abnormal tissue development.
What to do: Any new growth, bump, or change in the texture of your mouth should be examined by a dental or medical professional.
5. Numbness or Pain in the Mouth or Lips
Persistent numbness, tingling, or pain—especially if it occurs without obvious cause—may indicate changes in nerve function due to a growing lesion. The American Dental Association notes that sensory changes in the lips, tongue, or chin area should not be ignored, especially if they continue over time.
What to do: If you notice any loss of sensation or ongoing discomfort in your mouth or face, seek medical guidance.
6. Difficulty Chewing or Swallowing
Discomfort while eating or a feeling of something stuck in the throat may indicate a lesion affecting the throat or esophagus. Difficulty moving the jaw or tongue can also signal an underlying issue. According to the World Health Organization, early-stage head and neck cancers—including oral cancer—can present with swallowing or speaking difficulties.
What to do: If swallowing, chewing, or moving the jaw becomes uncomfortable or painful, consult a healthcare provider for evaluation.
7. Persistent Bad Breath
While bad breath (halitosis) can be caused by poor oral hygiene, persistent odor that doesn’t improve with brushing or mouthwash may indicate deeper issues. In some cases, underlying infections or tissue changes in the mouth can lead to chronic bad breath.
What to do: If bad breath is constant despite good hygiene and dental care, bring it up at your next dental or medical appointment.
Risk Factors for Oral Cancer
Understanding your risk factors can help prioritize early detection. According to the American Cancer Society and CDC, these include:
- Tobacco use (cigarettes, cigars, pipes, chewing tobacco)
- Heavy alcohol consumption
- Human papillomavirus (HPV) infection
- Excessive sun exposure (linked to lip cancer)
- Age over 40
- Poor nutrition
If you fall into one or more of these categories, regular oral screenings are even more important.
Importance of Regular Screenings
Early detection plays a vital role in improving outcomes. The Mayo Clinic recommends that individuals visit their dentist regularly, as dentists are trained to spot early signs of oral cancer during routine exams.
Tip: Dental checkups at least twice a year provide a valuable opportunity to catch potential issues early—often before symptoms become more severe.
When to Seek Medical Advice
Any of the following symptoms lasting more than two weeks should prompt a professional evaluation:
- Sores or patches in the mouth
- Lumps or unusual growths
- Persistent pain, numbness, or bleeding
- Difficulty swallowing or chewing
- Unexplained bad breath
You can start with your primary care provider or dentist, who may refer you to an oral surgeon or specialist for further testing if needed.
