Step-by-Step Path to Becoming a Dental Hygienist
Step 1: Complete Prerequisite Courses (1–2 Years)
Before applying to a dental hygiene program, you must complete prerequisite courses. Requirements vary by program but typically include:
| Prerequisite Course | Credits |
|---|---|
| Anatomy & Physiology I & II | 6–8 |
| Microbiology | 3–4 |
| Chemistry (General & Organic) | 6–8 |
| College English / Composition | 3–6 |
| Psychology | 3 |

Minimum GPA: Most programs require a 2.5–3.0 minimum GPA in prerequisite courses, with competitive programs expecting 3.2–3.8+.
Observation Hours: Many programs require 8–40 hours of observation or shadowing a dental hygienist before applying.
Important: Prerequisite courses take 1–2 years to complete. Plan ahead and check the specific requirements of programs you're interested in — they vary significantly between schools.
Step 2: Get Accepted Into a CODA-Accredited Program
Dental hygiene programs must be accredited by the Commission on Dental Accreditation (CODA) for graduates to be eligible for licensing. There are two main program types:
| Program Type | Duration | Degree | Cost |
|---|---|---|---|
| Associate Degree (AAS/AS) | 2–3 years | Associate of Applied Science | $8,000–$45,000 |
| Bachelor's Degree (BS) | 4 years | Bachelor of Science | $20,000–$80,000 |
Associate degree programs are the most common and typically sufficient for clinical practice. They are offered at community colleges and technical schools.
Bachelor's degree programs are offered at universities and provide broader education. They may be required for teaching, research, or public health positions.
Program Admission Statistics:
- Average acceptance rate: 25–40% (competitive programs can be below 20%)
- Average prerequisite GPA of admitted students: 3.3–3.7
