Why a two-year degree takes three years
Dental hygiene is usually an associate degree, but the BLS reports that programs typically take three years. Prerequisite courses are part of the reason: many schools expect college-level science before you start, so it is worth counting those courses when you plan the timeline.
Choosing a program
Licensing in most states depends on graduating from an accredited program, so check accreditation before anything else. In the United States, dental hygiene programs are accredited by the Commission on Dental Accreditation (CODA).
What the job pays
The national median was $98,100 a year, or $47.16 an hour, in May 2025. The BLS projects 8% job growth from 2025 to 2035, with about 15,000 openings a year.
