For applying to dentistry, focus on researching universities that fit your qualifications, such as King’s College London or the University of Manchester. While your UCAT score of 2850 is strong, gaining more work experience is crucial. Try to find opportunities to shadow dentists or volunteer in healthcare settings to enhance your application. Your personal statement should convey your passion for dentistry and what you've learned from your experiences. If direct entry proves challenging, consider related courses that can lead to dentistry later. Networking with current students or professionals can provide valuable insights and potential opportunities. Lastly, prepare thoroughly for interviews and have backup options in related fields. Good luck!
