Where Community Health Workers Actually Work: 7 Settings You Haven't Considered
12 May, 2026
If you've ever searched "what is needed to be a dentist," you probably noticed something quickly: the answer is long, expensive, and highly specific. Dental school alone takes four years after a bachelor's degree, and the total investment of time and money can feel staggering. But here's the question I don't see asked often enough — have you considered how dentistry stacks up against other rewarding healthcare careers that might match your interests with a very different commitment level?
I've spent years helping job seekers on healthcareers.app navigate exactly this kind of decision. Some people arrive absolutely certain they want to be a dentist, and I admire that clarity. But many others are in an earlier exploratory phase, weighing dentistry against careers in medical lab sciences, ophthalmic technology, or other allied health fields. This post is for all of you. We're going to break down what is needed to be a dentist, then place it side by side with two other careers — medical laboratory science and ophthalmic certification paths — so you can make an informed choice about where to invest your next decade of education and training.
Becoming a dentist begins long before dental school. You'll need a bachelor's degree — while there's no single required major, most aspiring dentists study biology, chemistry, or a related science. The critical piece is completing prerequisite coursework that dental schools require, which typically includes:
Your undergraduate GPA matters enormously. Dental school admissions are competitive, and most successful applicants carry a science GPA of 3.5 or higher. Beyond academics, you'll want to accumulate shadowing hours with practicing dentists, volunteer experience in healthcare settings, and leadership roles that demonstrate your readiness for a demanding professional program.
The Dental Admission Test is a standardized exam covering natural sciences, perceptual ability, reading comprehension, and quantitative reasoning. Most students spend three to six months preparing for the DAT, and scores play a significant role in admissions decisions. I always recommend treating DAT prep like a part-time job — the students who score highest typically dedicate structured, daily study sessions over several months.
Dental school is a four-year doctoral program leading to either a Doctor of Dental Surgery (DDS) or Doctor of Dental Medicine (DMD) degree. These are functionally equivalent — the curriculum is virtually identical, and the title difference reflects individual school tradition rather than a difference in training quality.
The first two years emphasize biomedical sciences, dental anatomy, and preclinical simulation work. Years three and four shift to hands-on clinical rotations where you'll treat actual patients under faculty supervision. This is where the reality of dentistry hits: you're performing extractions, restorations, and diagnostic procedures while managing patient anxiety and learning practice management skills simultaneously.
The financial commitment is substantial. According to the American Dental Education Association, average educational debt for dental school graduates consistently exceeds $250,000, and many graduates carry significantly more. This is a critical factor to weigh honestly.
After graduation, you must pass the National Board Dental Examinations (now called the Integrated National Board Dental Examination, or INBDE) and a regional or state clinical licensing exam. Only after passing these exams can you practice independently. Some dentists pursue additional residency training in specialties like orthodontics, oral surgery, or pediatric dentistry, adding two to six more years of education.
In total, the path from high school diploma to practicing general dentist takes a minimum of eight years — four undergraduate plus four dental school — with specialists requiring even more.
Now let's shift gears entirely. Medical lab sciences represent one of the most essential yet underappreciated corners of healthcare. Medical laboratory scientists (also called clinical laboratory scientists or medical technologists) perform the diagnostic testing that drives roughly 70% of all medical decisions. If you're drawn to science but want to enter the workforce years earlier than the dentistry timeline allows, this path deserves serious consideration.
A career in medical lab sciences typically requires a bachelor's degree in medical laboratory science or a closely related field, completed in four years. Many programs are accredited by the National Accrediting Agency for Clinical Laboratory Sciences (NAACLS) and include a clinical practicum in the final year where you rotate through hospital laboratories.
Core coursework covers:
After completing your degree, most employers expect or require certification through the American Society for Clinical Pathology (ASCP) Board of Certification. The certification exam is challenging but achievable with solid program preparation.
The contrast is striking. You can enter the medical lab sciences workforce with a four-year degree and national certification — no graduate school, no six-figure educational debt, and no additional licensing exams beyond your board certification. The Bureau of Labor Statistics consistently projects strong growth for medical laboratory scientists, driven by an aging population and advances in diagnostic medicine. Meanwhile, you're earning a professional salary four or more years before a dental student even graduates.
That said, the trade-offs are real. Medical lab scientists generally earn less than dentists over a career, and the work environment — primarily laboratory-based — is fundamentally different from the patient-facing nature of dentistry. If direct patient interaction and entrepreneurial practice ownership appeal to you, medical lab sciences may not scratch that itch.
For those who want to enter healthcare even faster, ophthalmic technology offers a compelling path. Ophthalmic technicians and technologists work alongside ophthalmologists and optometrists, performing diagnostic tests, assisting with procedures, and managing patient care in eye care settings.
Ophthalmic certification comes in tiered levels, each building on the last:
What I find especially appealing about ophthalmic certification is its flexibility. You can start working in the field with relatively minimal formal education, earn while you learn, and progressively advance your credentials and salary over time. It's a "build as you go" career model that contrasts sharply with dentistry's front-loaded, all-or-nothing investment.
Demand for ophthalmic professionals is growing alongside the broader expansion of eye care services. An aging population means more cataract surgeries, more glaucoma management, and more retinal procedures — all of which require skilled ophthalmic technicians and technologists in the room. Sources such as the Bureau of Labor Statistics project continued growth in ophthalmic medical personnel as part of the broader allied health expansion.
The earning potential is more modest than dentistry, but the debt-to-income ratio is far more favorable. Many ophthalmic assistants begin working with little to no educational debt, which creates genuine financial freedom that dentists won't experience for years or even decades after graduation.
Here's how these three paths stack up on the factors I see job seekers care about most:
There's no universally "best" answer here. What is needed to be a dentist is a massive commitment that pays off handsomely for people who are genuinely passionate about oral health and patient care. But if you're motivated primarily by wanting a stable, rewarding healthcare career without a decade of school and six figures of debt, medical lab sciences and ophthalmic certification offer legitimate alternatives that deserve more attention than they typically receive.
Before committing to any of these paths, I encourage you to sit with these questions honestly:
You can absolutely pursue dentistry with a non-science bachelor's degree, but you'll need to complete all the prerequisite science courses that dental schools require. This often means one to two additional years of post-baccalaureate coursework before you can even apply. Some universities offer structured pre-dental post-bacc programs designed for career changers.
Yes, and this is one of the underrated advantages of medical lab sciences. The foundational knowledge in pathology, microbiology, and clinical diagnostics transfers well to roles in pathologists' assistant programs, public health, pharmaceutical research, and healthcare administration. Some medical lab scientists use their experience as a springboard to medical school or physician assistant programs.
JCAHPO certification — whether at the COA, COT, or COMT level — is nationally recognized and widely respected by employers. However, specific scope-of-practice regulations vary by state, so I always recommend checking your state's requirements. Some states may require additional registration or have specific rules about which procedures ophthalmic personnel can perform.
Dentists earn significantly more in absolute terms, with the BLS consistently ranking dentistry among the highest-paid healthcare professions. However, when you factor in educational debt, years of lost income during training, and the time value of money, the gap narrows more than most people expect. Medical lab scientists and ophthalmic technologists earn competitive healthcare salaries with far lower startup costs. The "net worth crossover point" — where a dentist's cumulative net worth surpasses someone who started earning earlier with less debt — often doesn't arrive until the dentist's late thirties or early forties.
All three offer some flexibility, but the nature differs. Dentists in private practice can set their own schedules, though practice overhead creates pressure to maintain patient volume. Medical lab scientists often work shifts, including evenings and weekends in hospital settings, but part-time positions are available. Ophthalmic professionals typically work regular clinic hours, making it one of the more predictable schedules in healthcare.
Understanding what is needed to be a dentist is essential whether you ultimately pursue that path or decide it's not the right fit for your life. I've seen too many aspiring healthcare professionals lock into a single career vision without exploring alternatives, only to feel trapped by debt or disillusionment later. By examining dentistry alongside medical lab sciences and ophthalmic certification, you give yourself the context to make a genuinely informed decision — one that accounts for your financial reality, your timeline, your personality, and your long-term goals.
