Oral cancer is a severe condition that can affect the mouth, tongue, gums, and throat, with the potential to spread to other parts of the body. Early diagnosis is crucial, as it significantly impacts treatment and recovery rates. Dentists play an essential role in the early detection of oral cancer during routine checkups. They are trained to recognize subtle changes in the mouth, such as persistent red or white patches, sores that do not heal, or unusual swelling. By identifying these symptoms early, dentists can refer patients to oncologists for further examination and treatment. Additionally, dentists emphasize the importance of reducing risk factors such as tobacco use, excessive alcohol consumption, and poor oral hygiene. By incorporating preventive practices and early detection, dental professionals help safeguard patients' oral health and contribute to the fight against oral cancer.
