A dentist has drawn attention to often overlooked warning signs of oral cancer, emphasizing that some symptoms may manifest without even opening the mouth.

Oral cancer, commonly known as mouth cancer, can impact the tongue, gums, cheeks, and lips. While some indicators are apparent during dental check-ups, others can be less obvious. Dr. Deepa Chopra from Whites Dental stresses the importance of recognizing early changes. “Symptoms might develop gradually and be mistaken for minor issues,” Dr. Chopra noted. “Persistent alterations that don’t resolve in a few weeks should be professionally assessed.” Observable signs inside the mouth may include non-healing ulcers, unexplained bleeding, red or red-and-white patches, unusual lumps, or teeth becoming loose without a clear reason. However, Dr. Chopra pointed out that not all indicators are confined to the mouth’s interior.

“A sore throat that lingers, difficulty swallowing, discomfort while chewing, or constant ear pain could sometimes relate to changes in oral or surrounding tissues,” she mentioned. “Numbness in the lip or jaw area also merits further examination.”

She also noted that changes in speech might occasionally indicate an issue. “If someone experiences ongoing hoarseness, slurred speech, or a change in their voice that doesn’t improve, seeking medical or dental advice is advisable,” she advised.

Dr. Chopra emphasized that many of these symptoms are often linked to more common, less severe conditions. “For instance, bleeding gums are usually associated with gum inflammation rather than cancer,” she explained. “However, if symptoms are unusual, persistent, or worsening, it’s wise to have them evaluated.”

Certain lifestyle habits may elevate risk, such as tobacco use, excessive alcohol consumption, and overexposure to the sun on the lips.

“Regular dental examinations may help identify changes early, sometimes before a patient is aware of them,” Dr Chopra said. “Being familiar with what feels normal for you and seeking advice if something changes could support earlier detection.”

She emphasised that awareness does not mean alarm. “Most oral changes are not cancer,” she said. “But paying attention to ongoing symptoms and maintaining routine dental visits may be an important part of overall health.”
