So, let’s break down each step:
Step 1: Finish High School (4 years)
When: Ages 14–18
Goal: Build a strong academic foundation
In high school, focus on science and math classes like:
- Biology
- Chemistry
- Physics
- Algebra and Calculus
- Anatomy (if available)
Also, take part in extracurricular activities that build leadership, communication, and community service—these will help with college applications.
Tips for high school students:
- Maintain a high GPA (aim for 3.5 or higher)

- Volunteer at dental offices or clinics
- Shadow a local dentist to gain real-world experience
Step 2: Earn a Bachelor’s Degree (4 years)
When: Ages 18–22
Goal: Complete undergraduate education and prepare for dental school
While you don’t need a specific “pre-dental” degree, you must complete certain science prerequisites. Most students major in:
- Biology
- Chemistry
- Biochemistry
- Health Sciences
Typical prerequisite courses:
- General Biology with lab
- General Chemistry with lab
- Organic Chemistry with lab
- Physics
- English
- Mathematics
Important: Maintain a strong GPA (above 3.3) and build a strong application for dental school.
Step 3: Take the Dental Admission Test (DAT)
When: Junior or Senior year of college
Purpose: Standardized test for dental school admission
The DAT tests your academic ability, scientific knowledge, and perceptual skills. It includes:
- Natural Sciences (Biology, General and Organic Chemistry)
- Reading Comprehension
- Quantitative Reasoning
- Perceptual Ability
Preparation Tips:
- Start studying 3–6 months in advance
- Use DAT prep books and online tools
- Consider a prep course if needed
A competitive DAT score is typically 18–21 on a scale of 1–30.

Dental school is intense and demanding. The curriculum includes:
- First 2 years: Classroom and lab work in basic sciences (anatomy, physiology, pathology)
- Final 2 years: Clinical training with real patients under supervision
Key subjects:
- Oral pathology
- Periodontics
- Prosthodontics
- Radiology
- Dental materials
- Pharmacology
- Dental ethics
You will also take the National Board Dental Examinations (NBDE) in two parts to become licensed.

- Orthodontics (braces and jaw alignment) – 2–3 years
- Oral & Maxillofacial Surgery – 4–6 years
- Pediatric Dentistry – 2 years
- Periodontics (gum care) – 3 years
- Prosthodontics (restorative dentistry) – 3 years
