In short
To become a dental assistant, most people finish a 9-to-12-month certificate at a community college or trade school and then start in a dental office. Training runs about $2,000 to $15,000 before grants. The optional Certified Dental Assistant (CDA) credential, earned by passing three short exams, is recognized or required in many states. Dental assistants earned a median of about $47,300 a year in May 2024, according to the U.S. Bureau of Labor Statistics. Fill out the form to hear from programs near you.

Is this job for you?
Five honest questions. If most answers are yes, dental assisting is worth a look. Two things to weigh first: the pay is lower than several other trades, and the work is close-up and routine - you'll do the same steps many times a day, and you'll be responsible for keeping patients comfortable when they're nervous.
- Do you like working with people one on one, all day?
- Are you comfortable being close to someone's face and mouth, with gloves and a mask?
- Can you stay tidy and organized when things get busy?
- Do you want a schedule that is mostly weekdays, not nights or on-call?
- Are you okay doing the same careful steps again and again without losing focus?
If you want higher pay and don't mind physical work, compare HVAC, welding, or plumbing first.
What the work is like
On a typical day you prepare the room and the tray of instruments before each patient, bring the patient back, and stay chairside while the dentist works - handing over tools, keeping the area dry, and taking notes. You take and process X-rays if your state allows it, mix materials, and clean and sterilize everything afterward. You also do office-side tasks: scheduling, calling patients, and updating records.
The hours are one of the biggest draws. Most dental offices run Monday to Friday during the day. Some assistants later train into expanded duties or into front-office and practice-management roles, and a few go on to hygiene school, which pays much more but takes years.

How to get trained
Community college certificate
About 9 to 12 months. You learn anatomy, infection control, dental materials, chairside assisting, and often radiation safety, with hands-on practice in a clinic. Usually the cheapest route, and Pell and state grants can help pay.
Private trade school
Similar length, often faster start dates and more career-placement help, at a higher price. Ask for the total cost and last year's job-placement numbers in writing before you sign.
On-the-job training
Some dentists hire people with no formal training and teach them chairside, and you can add the CDA credential later. This can work, but it depends on finding an office willing to train you, and some states limit what an untrained assistant may do.
What school costs
| Where | Cost before aid | Time | Notes |
|---|---|---|---|
| Community college certificate | About $2,000–$6,000 | 9–12 months | Cheapest; Pell and state grants may apply |
| Private trade school | About $8,000–$15,000 | 9–12 months | Ask for cost and placement numbers in writing |
| On-the-job | $0 | Varies | You learn while paid, but you depend on the office |
The three CDA exams usually cost extra. Some programs include them; ask.
What it pays
| Stage | Typical yearly pay | What you're doing |
|---|---|---|
| Starting out | Around $30,000–$36,000 | New assistant, learning the office's routines |
| Median | About $47,300 | Working assistant, often holding the CDA credential |
| Top 10% | Over about $61,780 | Experienced, expanded duties, or lead assistant |

Questions about dental assisting
What is the CDA credential, and do I need it?
The Certified Dental Assistant credential comes from DANB and is recognized or required in many states. To earn it you pass three exams - Radiation Health and Safety, Infection Control, and General Chairside Assisting. You qualify through a dental assisting program, through 3,500 hours of supervised work experience, or through certain dental degrees, and you need current CPR. The CDA must be renewed each year.
Do I take X-rays?
Many dental assistants take X-rays, but what you're allowed to do depends on your state and sometimes on extra training or certification. Ask the school how its program handles radiation safety, and ask the state dental board what your state allows.
Is dental assisting a good career for the long term?
It's steady work with regular hours and low entry cost, but the pay tops out lower than the skilled trades, and many assistants move on after a few years. If you want to stay in dentistry, you can grow into expanded duties, office management, or go back to school for hygiene, which pays much more.
Can I train while I work another job?
Often yes. Many certificate programs offer evening or part-time tracks. It may take longer than the full-time schedule. Tell the school your hours and see what fits.
Do I need a high school diploma or GED?
Most programs and employers want one. If you don't have it yet, some schools help you earn a GED first or at the same time. See our GED page for how it works in your state.
