Introduction: Oral cancer is also known as mouth cancer that is the cancer of the lining of the lips, mouth, or upper throat. In the mouth, it commonly starts as a painless white patch and develops into red patches. It commonly looks like a persistent ulcer that does not heal and slowly grows. Symptoms may include difficult or painful swallowing, new lumps in the neck, swelling in the mouth, feeling of numbness in the mouth, or lips and risk factors include tobacco and alcohol use. Objective: To create awareness of risk factors of oral cancer among school students. Methods: The study setting was done using a prospective observational study in Saveetha Dental College (SDC). Approval is received from the scientific review board, (SDC). The sampling method is random sampling including the sample size of 100 participants. A self-structured questionnaire was prepared including 15 questions. Results: The results were collected and analyzed using statistical analysis using online SPSS software. According to the results, 65% of school students are aware of oral cancer. Almost 70% of school students believe that oral cancer leads to death. Students also know that smoking causes oral cancer.
