Dental experts are urging the public to take persistent mouth sores seriously, as they could indicate a more serious health condition, including cancer. According to Dr. Andrej Bozic, an oral surgeon at Dentum in Croatia, which treats numerous British patients each year, any sore in the mouth lasting longer than two weeks warrants immediate examination.
While factors like cold weather, weakened immunity, and stress can lead to an increase in mouth ulcers during the winter months, Dr. Bozic emphasizes that ulcers typically resolve within a week or two. He states, “Most ulcers are harmless and clear within a week or two. But if one persists, bleeds, or keeps coming back in the same spot, it’s a red flag that shouldn’t be dismissed.”
Understanding the Risks of Persistent Ulcers
Most mouth ulcers result from stress, friction, or accidental injuries, such as biting the cheek. However, lasting sores can sometimes be a sign of early oral or throat cancer, particularly in individuals who smoke, consume alcohol excessively, or are infected with human papillomavirus (HPV). The rising rates of these cancers in the UK are concerning. The Oral Health Foundation reports that mouth cancer cases have doubled over the past two decades, while HPV-related throat cancers have become some of the fastest-growing cancer types, particularly among men.
Dr. Bozic warns, “These cancers often start small and painless. You might not feel unwell, so the temptation is to wait and see if it heals. But catching it early makes all the difference.” Dentists and oral surgeons frequently serve as the first line of defense in identifying early tissue changes, which may include white or red patches, non-healing ulcers, or thickened areas inside the mouth.
Recognizing Warning Signs and Prevention
Dr. Bozic advises that anyone observing symptoms such as persistent sores should seek a dental check-up without delay. “If you notice any of these symptoms, don’t wait for it to hurt,” he said. “Early detection gives the best chance of full recovery.”
To promote oral health and increase the likelihood of early detection, Dr. Bozic recommends maintaining regular dental check-ups every six months. He explains, “Your dentist isn’t only checking for cavities. We’re also trained to spot early signs of cancer, infections, and other diseases that may first appear inside the mouth.”
In addition to regular visits, he emphasizes the importance of good oral hygiene, avoiding tobacco, and limiting alcohol consumption, both of which are major risk factors for oral and throat cancers. He also encourages HPV vaccinations for young people, as prevention plays a crucial role in reducing cancer risks.
Dr. Bozic concludes, “Most ulcers are nothing to worry about. But if one refuses to heal, don’t wait. Getting it checked could save your life.” The message is clear: being proactive about oral health can significantly enhance outcomes in the fight against serious conditions.
