Meet Emily, a 20-year-old health sciences student at the University of Waterloo, who has a keen interest in dentistry. After recently undergoing a wisdom tooth extraction, she took to Reddit to share her experience with local anesthesia and the relief it brought her. In her free time, Emily is an active member of the campus pre-dental society and volunteers at a local dental clinic, dreaming of one day becoming an oral surgeon. Her upbeat personality reflects her belief that sharing knowledge and experiences can help others navigate their own health journeys.
