Applicant,
To answer your questions:
1)Q: How much work is dental school?
A: Although I don't start dental school until next year, I have many friends that are current dental students in various dental schools in the U.S. Dental schools are A LOT of work from what I've heard. Some would even say it's harder than medical school in some cases, for instance, the first two years, dental and medical schools are fairly similar in their curriculi with all basic science courses (Biochemistry, Histology, Gross Anatomy, Physiology, Pathology, Microbiology, Neuroanatomy, and Immunology). With dental schools, in addition to all these basic science courses, we have pre-clinical laboratory courses that we have to attend that medical students do not have. According to some, dental schools are much more time consuming than medical schools.
2) Q:Is it really hard and you have to be always working in dental school during the 4 years?
A: Yes and No! Yes, because if you want to get good grades and be competitive for specialties after 4 years of pre-doctoral dental education, you must dedicate all your free time to your studies. To get in "some" specialties, you must aim to be in top 10% of your class speaking generally. The answer is partly No because dental students that I know (my friends) are some of the craziest partiers I know. They work hard and they play hard. Four years of dental school should not only be educational, but it should also be a great time in your academia life. You'll definitely have time to party and relax, trust me on this one.
3) Q:What about after dental school?
A: After your pre-doctoral dental education, you'll have two major path ways. One, you go into a practice and start to do dental work as general dentists. Two, you continue dental education with POST-DOCTORAL dental education (specialties = ENDO, ORAL SURGERY, ORTHO, PROSTHO, PEDO, PERIO, or Advance Education General Dentistry [AEGD] or General Practice Residency [GPR]) There's much to say about each of the post-doctoral dental education programs, we won't get into them here. Regardless which pathway you choose, I guarantee you that you'll also have fun doing it. Remember, "DENTISTRY IS FUN"!!
General break down of 4 years of pre-doctoral dental education:
Year 1: Basic Sciences (50%) and Pre-clinical labs (50%)
(some dental schools will incorporate patient exposure at the end of year 1 or even during year 1 or during year 2)
Year 2: More Basic Sciences (40%) and More Pre-clinical labs (60%)
Year 3: Clinic exposure (70%) and lectures on specialties (30%)
Year 4: General and Specialty Clinics (90%) and Electives (10%)
Again, this 4 year curriculum outline is VERY general. Every dental school will vary from this curriculum backbone. If you're interested in a particular dental school, I would suggest you to look up their school's website and look for their curriculum structure.
To sum, dental school will be tough and challenging, but it also should a great time in your life. Will you have fun during dental school, you bet ya!
Hope this helped.
