I picked ones that highlighted dentistry but also others that highlighted skills that are important to dentistry, like teamwork, leadership and of course hobbies that promote manual dexterity. I think it's important to balance your experiences. Of course you want to showcase that you have experience in the field, but I think it's also important to demonstrate that you have other interests/hobbies/ECs that have shaped your skills, passion and personality. Hope that helps 🙂
