If you're preparing for dental school, one of the first questions you'll ask is: how many dental shadowing hours do I need? The answer depends on which schools you're targeting, but the short version is: aim for 100-200 verified hours to be competitive.
This guide breaks down the requirements by school, explains what counts (and what doesn't), and shows you how to log and verify your hours efficiently.
Here are the shadowing hour requirements and recommendations for top dental schools:
| School | Required | Recommended |
|---|---|---|
| Harvard School of Dental Medicine | 100 hours | 200+ hours |
| Columbia University CDM | 100 hours | 150+ hours |
| NYU College of Dentistry | Not specified | 100+ hours |
| University of Michigan | Not specified | 100+ hours |
| UPenn School of Dental Medicine | Not specified | 150+ hours |

| Boston University GSDM | Not specified | 100+ hours |
| Tufts University SDM | Not specified | 100+ hours |

Not everything you do in a dental office counts as shadowing. Here's the breakdown:

Logging 100+ hours is just the minimum. Here's how to make your shadowing experience stand out on your application:
Most dental schools recommend 100-200 hours of verified shadowing. The national average for accepted applicants is approximately 150 hours. Some schools require a minimum (Harvard: 100 hours, UCLA: 50 hours) while others list it as "strongly recommended."
Dental shadowing hours include time spent observing a licensed dentist during patient care — examinations, procedures, surgeries. Dental assisting, lab work, and administrative tasks do NOT count. Virtual shadowing is generally not accepted by most dental schools.
Yes. Most dental schools require hours to be verified by the supervising dentist with their signature, license number, and/or NPI number. Dental Now provides digital verification with NPI-backed certificates that are accepted by all dental schools.
Absolutely — and schools encourage it. Shadowing across general dentistry, orthodontics, oral surgery, pediatric dentistry, and other specialties demonstrates breadth of interest and a well-rounded understanding of the profession.
Start as early as your sophomore year of college. This gives you time to accumulate 100+ hours before applications open. Starting early also lets you build relationships with dentists who can write strong letters of recommendation.
