TRI-COUNTY DENTAL HYGIENISTS' ASSOCIATION
Get to Know Us
We are a component of the Ohio Dental Hygienists' Association as well as a part of the American Dental Hygienists' Association. Our component is in Northeastern Ohio and consists of three counties: Trumbull, Mahoning, and Columbiana.
Tri-County DHA is committed to supporting dental hygiene students and practicing dental hygienists so they may continue to learn and grow in their careers as dental hygiene professionals. Please feel free to look around our site and contact us with any questions.
​
Our Ohio State Dental Board-approved Medical Emergencies course can be found on our Courses Page. Upon completion of this course and other specified requirements, dental hygienists may practice without a dentist present.
