A dental expert has issued a critical warning regarding persistent mouth sores that last longer than two weeks. According to Dr. Andrej Bozic, an oral surgeon at Dentum in Croatia, which treats numerous British patients each year, such symptoms should not be ignored as they could indicate more serious health issues.
Dr. Bozic explained that while many mouth ulcers are benign and typically heal within a week or two, any sore that lingers, bleeds, or recurs at the same site is a potential red flag.
Understanding the Risks of Persistent Mouth Ulcers
The majority of mouth ulcers arise from stress, accidental bites, or irritation. However, stubborn sores can sometimes indicate early-stage oral or throat cancer, particularly in individuals who smoke, consume alcohol heavily, or have a history of human papillomavirus (HPV). Alarmingly, the Oral Health Foundation reports that the incidence of mouth cancer in the UK has doubled over the past two decades, while HPV-related throat cancers are among the fastest-growing cancer types, disproportionately impacting men.
“These cancers often start small and may not cause any immediate discomfort,” Dr. Bozic noted. “This can lead to a false sense of security, prompting individuals to delay seeking medical advice. Early detection is crucial for effective treatment.”
Identifying Warning Signs and Preventive Measures
Dr. Bozic emphasized the importance of vigilance regarding oral health. Individuals should seek dental evaluations promptly if they experience symptoms such as persistent sores, white or red patches, or thickened areas in the mouth. “If you notice any of these symptoms, don’t wait for it to hurt,” he recommended. “Early detection gives the best chance of full recovery.”
Regular dental check-ups, ideally every six months, are one of the most effective strategies for early detection of serious conditions. “Your dentist isn’t only checking for cavities,” Dr. Bozic remarked. “We are also trained to detect early signs of cancer, infections, and other diseases that may manifest in the mouth.”
In addition to regular dental visits, Dr. Bozic advises maintaining good oral hygiene, avoiding tobacco, and limiting alcohol consumption—all significant risk factors for oral and throat cancers. He also advocates for HPV vaccination for young people to reduce their risk of related cancers.
“Most ulcers are nothing to worry about,” he concluded. “However, if a sore refuses to heal, don’t hesitate to seek professional advice. Getting it checked could save your life.”
