People with a history of mouth ulcers are receiving a serious health alert. Mouth ulcers, also known as canker sores or aphthous ulcers, are common and mostly harmless. These painful sores appear on the soft tissues of the mouth, such as the inner cheeks, lips, tongue, and gums. Typically circular or oval-shaped, they feature a red, inflamed border with a white, yellow, or grey center. While usually benign, non-contagious, and self-resolving within one to two weeks, prolonged ulcers should not be overlooked.
A dentist has emphasized the importance of not ignoring persistent mouth ulcers, as they could potentially be an early indication of cancer if they endure longer than expected. This cautionary statement comes amidst a rise in oral and throat cancer cases in the UK. Factors like cold weather, weakened immunity, and stress can increase the prevalence of ulcers during winter, but any sore persisting beyond two weeks warrants attention, according to Dr. Andrej Bozic, an oral surgeon at Dentum.
Dr. Bozic highlighted that while most ulcers heal within a week or two, ongoing, bleeding, or recurrent sores demand prompt evaluation. Such sores may signal early stages of oral or throat cancer, particularly in individuals who smoke, drink heavily, or have HPV. Stress, friction, or accidental cheek biting typically cause the majority of mouth ulcers.
In the UK, oral and throat cancers are on the rise, with mouth cancer cases doubling over the past two decades. Dr. Bozic stressed the importance of early detection, as these cancers often begin painlessly and inconspicuously. Dentists and oral surgeons are usually the first to notice initial tissue changes, like white or red patches, persistent ulcers, or thickened areas inside the mouth.
Dr. Bozic advised immediate consultation if any concerning symptoms manifest, emphasizing that early detection significantly improves recovery chances. Regular dental check-ups every six months are a simple yet effective way to identify serious conditions early. Maintaining good oral hygiene, abstaining from tobacco, limiting alcohol consumption, and ensuring HPV vaccination for young individuals are recommended preventive measures. While most ulcers pose no threat, unresolved sores should not be disregarded, as timely intervention could be lifesaving.
According to the NHS, a pharmacist can suggest treatments to expedite healing, prevent infection, or alleviate pain for mouth ulcers. While these ulcers are usually benign and resolve within a week or two, persistent ulcers lasting over three weeks necessitate a GP or dentist visit.
Most solitary mouth ulcers stem from avoidable causes, such as lifestyle habits, while some triggers are beyond control. Multiple mouth ulcers could indicate underlying health issues.
