Dentists diagnose and treat conditions affecting the teeth, gums, and oral structures. They fill cavities, perform root canals, extract teeth, place crowns and bridges, treat gum disease, prescribe medications, take and interpret dental X-rays, and educate patients about proper oral hygiene and preventive dental care. Some dentists specialize in areas such as orthodontics (braces and alignment), oral surgery (extractions and jaw surgery), pediatric dentistry (children), periodontics (gum disease), endodontics (root canals), or prosthodontics (dentures and implants). Dentistry offers a distinctive combination of hands-on clinical skill, foundational scientific knowledge, artistic precision in restorative and cosmetic procedures, and the opportunity for business ownership and entrepreneurship that many practitioners find deeply satisfying and professionally fulfilling throughout their careers. Most general dentists in the United States ultimately own or co-own their own private practices, giving them a level of professional autonomy that is increasingly rare in physician practice.
Education Pathway
Becoming a dentist requires approximately 8 years of post-secondary education. Undergraduate (4 years): Complete a bachelor’s degree with prerequisite courses (biology, general chemistry, organic chemistry, physics, biochemistry, English). Dental school prerequisites are similar to medical school prerequisites. DAT®: Take the Dental Admission Test, a standardized exam that tests natural sciences, perceptual ability (spatial reasoning), reading comprehension, and quantitative reasoning. See our DAT® prep guide. Dental School (4 years): Dental school leads to a Doctor of Dental Surgery (DDS) or Doctor of Dental Medicine (DMD) degree. The two degrees are functionally identical. The first 2 years focus on biomedical sciences (anatomy, physiology, biochemistry, pathology) and preclinical dental training (simulation labs where you practice procedures on models). The final 2 years are primarily clinical, with students treating patients under faculty supervision. Apply through AADSAS (Associated American Dental Schools Application Service). See our AADSAS guide. Optional Specialization (2 to 6 years): General dentists can practice immediately after dental school. Specialists (orthodontists, oral surgeons, periodontists, etc.) complete additional residency training lasting 2 to 6 years depending on the specialty.
What Dentists Do
A typical day for a general dentist in private practice includes examining patients (checking for cavities, gum disease, oral cancer, and other conditions), performing procedures (fillings, crowns, root canals, extractions, teeth whitening), taking and reviewing dental X-rays, developing treatment plans, counseling patients on oral hygiene and preventive care, and managing the business operations of the practice (staffing, scheduling, billing, equipment maintenance). Dentists work closely with dental hygienists (who perform cleanings and preventive care) and dental assistants (who assist chairside during procedures).
The variety within a general dentistry day is one of the profession’s appeals: in a single morning, you might do a routine cleaning exam, perform a complex root canal, discuss orthodontic options with a teenager, and treat a dental emergency (a broken tooth, an abscess). Specialists have more focused daily routines: an orthodontist adjusts braces and aligners all day, an oral surgeon performs extractions and jaw surgeries, and a pediatric dentist works exclusively with children and adolescents.
Salary and Job Outlook
The median annual salary for dentists is approximately $170,000, according to the Bureau of Labor Statistics, with specialists earning significantly more (orthodontists and oral surgeons often exceed $250,000 to $400,000). Dental school tuition is substantial, averaging approximately $250,000 to $350,000 for the entire four-year program at private dental schools and $150,000 to $250,000 at public schools. Dentists who own their practices have higher earning potential but also bear the financial risks and administrative responsibilities of business ownership. The profession is projected to grow 4 percent through 2032, with demand strongest in underserved and rural areas.
Advantages and Challenges
Advantages: High clinical autonomy (especially in private practice), strong financial compensation, regular work hours (most dental offices operate weekdays with limited evenings and weekends), the ability to own your own practice, lower call burden compared to physicians (dental emergencies are less common and less severe than medical emergencies), and a tangible, visible impact on patients’ health and confidence.
Challenges: Dental school debt is comparable to medical school debt but without the physician’s higher long-term earning ceiling in most specialties, the physical demands of dentistry (maintaining ergonomic positions for hours of detail-oriented work) lead to high rates of musculoskeletal issues among practicing dentists, practice ownership involves significant business risk and administrative burden, and the profession faces increasing competition from corporate dental chains that can reduce the autonomy and earning potential of independent practitioners.

Getting Started
Middle school: Explore science courses and healthcare careers. High school: Take AP® sciences, volunteer in clinical settings, and shadow a dentist. Undergraduate: Complete prerequisites (similar to pre-med), build clinical experience (dental office volunteering or shadowing is particularly relevant), prepare for the DAT®, and apply through AADSAS.
Private Practice vs. Corporate Dentistry: One of the biggest decisions facing new dentists is whether to pursue private practice ownership or join a corporate dental organization (also called a Dental Service Organization or DSO). Private practice offers maximum clinical autonomy (you decide how to treat each patient, what materials to use, and how to run the business), the potential for higher long-term earnings, and the satisfaction of building something that is entirely yours. However, practice ownership requires significant upfront capital ($300,000 to $500,000+ to purchase or start a practice), business management skills (hiring, marketing, accounting, compliance), and the financial risk of entrepreneurship. Corporate dentistry offers a guaranteed salary, lower financial risk, fewer administrative responsibilities, and a structured career path, but it may come with production quotas, less clinical autonomy, and a lower income ceiling compared to successful private practice owners. Many new dentists start in corporate or associateship positions to build clinical experience and pay down debt before purchasing their own practice.
Dental Specialties: Dentists who want to specialize complete 2 to 6 additional years of residency training after dental school. The nine recognized dental specialties are Orthodontics (braces, aligners, and jaw alignment; 2-3 year residency; among the highest-earning dental specialties), Oral and Maxillofacial Surgery (extractions, jaw surgery, facial trauma; 4-6 year residency; often the highest-earning dental specialty), Periodontics (gum disease treatment and dental implants; 3 year residency), Endodontics (root canal therapy; 2-3 year residency), Prosthodontics (crowns, bridges, dentures, and implants; 3 year residency), Pediatric Dentistry (dental care for children and adolescents; 2-3 year residency), Oral Pathology (diagnosis of oral diseases; 3 year residency), Dental Public Health (population-level oral health; 1-2 year residency), and Oral Radiology (dental imaging interpretation; 2 year residency). Specialty training is competitive, and admission to residency programs requires a strong dental school record.
Oral Health and Overall Health: One of the most compelling aspects of dentistry as a career is the growing recognition that oral health is integral to overall health. Research has established connections between periodontal (gum) disease and cardiovascular disease, diabetes, adverse pregnancy outcomes, respiratory infections, and Alzheimer’s disease. Dentists are increasingly recognized as primary care providers for the oral cavity who play a critical role in screening for systemic diseases (oral cancers, diabetes, nutritional deficiencies) that manifest in the mouth. This rapidly expanding understanding of the oral-systemic connection elevates the importance of dentistry within the broader healthcare system and creates opportunities for interprofessional collaboration between dentists and physicians.
