Thanks for the advice! Do you think the volunteering portion should be listed as a "dental experience" or "volunteer"?
Here's the definition of volunteering and other experiences on the AADSAS apps
Academic Enrichment: Programs sponsored by colleges, universities or other not–for–profit organizations (e.g., Summer Medical and Dental Education Program/Summer Health Professions Education Program).
Dental Experiences: Time spent officially following and observing a health care professional at work, preferably a dentist. When listing a dental experience, please specify the type of dentist you shadowed in the description text box (e.g., general dentist, orthodontist, etc.).
Employment: Paid work done outside of the dental care field; for example, a non-dental healthcare experience, retail or restaurant job.
Extracurricular Activities: Any sports teams and other activities through a college or university.
Research: Research projects done in addition to classroom work; research should NOT appear as credit on a school transcript.
Volunteer: Volunteer work done outside of the health care field; for example, working for Habitat for Humanity, tutoring students, participating in or working for a fundraiser walk or blood drive, etc.
You will notice that volunteer = outside of healthcare volunteering.
So, your shadowing and volunteering should be part of the dental experiences. They can be separate experiences, but it won't be under volunteering.
