Common questions
Do I need dental assisting experience first?
It is not always required, but many hygiene programs award admission points for assisting experience and shadowing hours — and it confirms you like the work before committing two years.
What prerequisites do hygiene programs require?
Typically anatomy & physiology, microbiology, chemistry, and English composition, plus entrance testing at some schools (often the TEAS).
How competitive is admission?
Very — many programs admit once a year with limited seats. A complete checklist (prereqs, shadowing, application timing) is the difference-maker.
