Most dentists finish a bachelor’s degree with science prerequisites, take the Dental Admission Test (DAT), complete a four-year dental school program that awards a DDS or DMD, then pass a national written exam and a clinical exam to earn a state license. That usually means about eight years after high school. Specialists such as orthodontists and oral surgeons add a residency on top.
What a dentist’s day actually looks like
Dentistry is hands-on, detailed work in a small space, often with a nervous patient.
- Clinical work: exams, fillings, crowns, root canals, extractions and treatment plans, using fine motor skills for hours at a time.
- Team leadership: dentists direct dental hygienists, assistants and front office staff, and the mood of the office often follows the dentist.
- Business decisions: many dentists eventually own or co-own a practice, which means hiring, equipment, insurance billing and budgets on top of patient care.
- Settings: private practices, group practices, community health centers, hospitals, the military and public health agencies.
If the patient side appeals but eight years does not, see how to become a dental hygienist.
Education: from prerequisites to dental school
- Undergraduate years: any major works, but you need biology, general and organic chemistry, physics and often biochemistry. Many applicants major in biology or chemistry; see what you can do with a biology degree if you want a backup plan built in.
- The DAT: a standardized exam covering natural sciences, perceptual ability (spatial reasoning), reading comprehension and quantitative reasoning.
- Dental school: four years at a program accredited by the Commission on Dental Accreditation (CODA). The first years are heavy on science and lab work on models; the later years move into supervised patient care.
- Residency: optional for general dentists, required for specialties like orthodontics, oral surgery, pediatric dentistry and periodontics, and it can add two or more years.
Licensing in plain terms
Every state requires a license to practice. The usual pieces are graduating from an accredited dental school, passing the Integrated National Board Dental Examination (INBDE), and passing a clinical licensure exam or, in some states, completing a residency year instead. Many states add a law and ethics exam. Requirements vary by state, so check the dental board in the state where you plan to work.
The path, step by step
- In high school, take biology, chemistry and the most math you can handle, and build steady study habits. Dental school admissions look closely at science grades.
- Shadow a general dentist and at least one specialist. Most dental schools expect real shadowing hours, and the experience tells you more than any brochure.
- In college, plan your prerequisites early, keep your science grades strong and find volunteer work that puts you around patients or underserved communities.
- Study for the DAT on a real schedule and take it the spring or summer before you apply.
- Apply through the centralized dental school application, with letters of recommendation and a personal statement.
- Finish dental school, pass the INBDE and your clinical exam, and apply for your state license. Decide whether to practice right away or apply to a residency.
The road overlaps heavily with medicine, so our pre-med roadmap is useful reading, and many applicants take a year to work and strengthen their file; see a gap year before professional school.
Checking the fit before you spend eight years
- Work as a dental assistant or front desk staff for a summer. You see the real rhythm of the office.
- Ask a dentist for an informational interview and ask what surprised them about owning a practice.
- Notice how you feel about close, precise handwork. Hobbies like model building, sculpting or playing an instrument are a decent early signal.
- Read through careers for people who like science to see neighboring options.
Who thrives, and why some leave
Dentistry suits people who like precision, can put an anxious person at ease and are comfortable eventually running a small business. The common reasons people reconsider are the cost and length of training, the physical strain on the neck, back and hands, and the isolation some feel working chairside all day. Experienced dentists sometimes shift into teaching, public health or administration.
Changing careers into dentistry
Career changers are common in dental school classes. Many take post-baccalaureate courses to finish prerequisites while working. The question is less about age and more about whether the debt and the years make sense for your life; our guides on changing careers and whether to go to grad school help frame it. For current pay and outlook, check the Bureau of Labor Statistics Occupational Outlook Handbook.
Where a mentor helps
Pre-dental students juggle prerequisites, shadowing, volunteering, the DAT and applications all at once. A mentor helps them explore whether dentistry is the right fit, build a semester-by-semester plan, stay accountable through hard science courses and DAT prep, keep applications on schedule and adjust to dental school. Mentors are not credentialed career counselors, admissions counselors or licensing experts. See career and education mentoring and mentoring for pre-med and pre-health students.

Common questions
How long does it take to become a dentist?
Usually about eight years after high school: four years of college and four years of dental school. Specialties add a residency of two or more years.
What is the difference between a DDS and a DMD?
Nothing practical. They are two names for the same dental degree, and both lead to the same licensing exams and the same work.
Do I have to major in biology to get into dental school?
No. You can major in anything as long as you finish the science prerequisites and do well in them. A major you enjoy often helps your grades.
Is the DAT hard?
It is demanding mainly because it covers so much: biology, chemistry, spatial reasoning, reading and math. Most people study for several months on a set schedule.
