If you are interested in pursuing a career in the health care industry as a dental hygienist, then look into BTC’s Dental Hygiene program. You'll learn the clinical skills and core professional values needed to launch a rewarding dental hygiene career in private and public settings, such as dental offices and public health clinics. The Dental Hygiene Program is designed for students interested in pursuing an education for entry into the profession of Dental Hygiene. A cohort of 10 students will be accepted into the Dental Hygiene Program each application year.

The Dental Hygiene Program at Bellingham Technical College is designed as a sequence of didactic, laboratory and clinical courses that fulfill the educational objectives established by the American Dental Association (ADA) Commission on Dental Accreditation. The Program is 7 consecutive quarters in length. BTC Dental Hygiene students learn under the supervision of licensed dentists and dental hygienists on state-of-the-art equipment in BTC’s on-campus dental clinic. Upon successful completion, students are awarded an Associates Degree in Applied Science-Transfer (AAS-T) and are eligible for licensure as a Dental Hygienist in WA State. Program graduates are well-positioned for employment in the dental industry, with the hands-on clinical experience employers need today.

Dental Hygiene Scope of Practice

Licensure Eligibility Requirements

To practice as a dental hygienist in the state of Washington (WA), you must be licensed through the Washington State Department of Health. The Revised Code of Washington (RCW) 18.29 and the Washington Administrative Code, Chapter 246-815 (WAC) outline the practice, act, and licensure criteria for dental hygienists. Specifically, the Department of Health - Dental Hygiene Licensure site details the licensure requirements. In addition to earning your AAS-T degree from the Bellingham Technical College Dental Hygiene Program, you will also be required to successfully pass the National Dental Hygiene Board Examination, the WA State Drug and Law exam, the WA state approved local anesthesia written and practical exams, a WA state approved restorative practical exam, and a WA state approved dental hygiene practical exam.

Note: BTC has not made a determination that the Dental Hygiene curriculum meets educational requirements for licensure/certification outside of Washington State. We encourage students who plan to work out-of-state to check relevant local licensure/certification requirements.

  • Employment and Wage Data Sources

    1Employment data come from the Washington State Board for Community and Technical Colleges (SBCTC) and reflect WA/OR employment for students enrolled at BTC between 2017-18 and 2019-20. Students are included in the employment rate if they left with a credential. Rates are not shown for programs with fewer than 10 students meeting the above criteria.

    2Whatcom County and WA State wage data come from Washington State Employment Security Department (ESD) 2021 Occupational Employment and Wage Estimates and reflect 2018-21 employment. Wage data represent occupations that BTC faculty have identified as the most relevant career paths for program graduates. Note that these wages reflect employees with varying educational levels/credentials. For cases in which multiple occupations have been identified by faculty, a weighted percentile is calculated using each occupation’s percentile wage and employment size estimate. Wages are not shown for programs for which occupations do not meet the ESD’s minimum thresholds for publishing. If the program has wage data from the Washington SBCTC that involves shift work, these ESD wages reflect the same number of hours used in the annual wage calculation. Starting wage = 25th percentile, median wage = 50th percentile, wage potential = 75th percentile.
