The Degree You Need to Become a Dental Hygienist

Quick Answer: What Should I Major In To Become A Dental Hygienist?

The direct path to becoming a dental hygienist is an associate degree in dental hygiene from a program accredited by the Commission on Dental Accreditation (CODA). This two-to-three-year degree qualifies graduates for state licensure and entry-level clinical positions. While a bachelor’s or master’s degree in dental hygiene opens doors to research, education, and administrative roles, the associate degree remains the most common and efficient route, with over 80% of practicing dental hygienists holding this credential according to the American Dental Hygienists’ Association (ADHA, 2024).

What Is the Most Common Major for Dental Hygienists?

The most common major for aspiring dental hygienists is an Associate of Applied Science (AAS) in Dental Hygiene. According to the ADHA’s 2024 workforce survey, 82% of licensed dental hygienists in the United States entered the profession through an associate degree program. This degree typically requires 60-80 credit hours of coursework combining general education prerequisites with specialized clinical training. Programs are offered at community colleges, technical schools, and some universities. The AAS in Dental Hygiene is designed specifically to prepare students for the National Board Dental Hygiene Examination (NBDHE) and state clinical board exams, making it the most direct educational pathway.

What Are the Prerequisites for a Dental Hygiene Program?

Before entering a dental hygiene program, students must complete prerequisite coursework in the sciences. According to the American Dental Education Association (ADEA, 2025), most CODA-accredited programs require the following prerequisites:

Prerequisite Subject	Typical Credit Hours	Common Course Titles
Biology with lab	4-8	General Biology I & II
Chemistry with lab	4-8	General Chemistry I & II
Anatomy & Physiology	6-8	Human Anatomy, Human Physiology
Microbiology	3-4	General Microbiology
English Composition	3-6	College Writing I & II
Psychology	3	Introduction to Psychology
Speech/Communication	3	Public Speaking or Interpersonal Communication

The ADEA reports that the average prerequisite completion time is 1-2 years of full-time study. Students who have already earned a bachelor’s degree in another field can often complete these prerequisites in one year before applying to a dental hygiene program.

What Coursework Is Included in a Dental Hygiene Degree?

A CODA-accredited dental hygiene program includes both didactic and clinical components. According to the Commission on Dental Accreditation’s 2025 standards, the curriculum must cover:
