Oral cancer, a form of head and neck cancer, poses a significant threat to oral health and overall well-being. Early detection plays a pivotal role in improving survival rates, and dentists are often the first line of defense. Through regular checkups, they are able to identify early signs such as persistent sores, lumps, or unusual discoloration in the mouth. Dentists are trained to conduct thorough oral exams and can spot abnormalities that may go unnoticed by patients. In addition to detection, they play an important role in educating patients about lifestyle changes to reduce risk factors like smoking and excessive alcohol consumption. Encouraging preventive care, including proper oral hygiene and a balanced diet, contributes to both oral health and the prevention of oral cancer, ensuring better outcomes for patients.
