In the US, dentists are microsurgeons specializing in teeth. Dental schools are slightly more competitive to enter than medical schools and, as in medical schools, students shoulder work loads equivalent to 26-28 undergraduate credits per semester. 1st year dental labs are measured in tenths of millimeters, and things get more exacting after that. Students who persevere earn the a DDS (Doctor of Dental Surgery) or DMD (Dental Medical Doctor) degree. Many will go on to spend 1-2 years in an optional residency (to gain experience) or specialty fellowships before entering dental practice. General dentists are trained to do almost anything that can be done with teeth, from cosmetics to orthodontics to implants, but many will refer odd or difficult cases to a specialist; for example, a root canal on a long, curved root might be referred to an endodonist, a dentist who is specially trained and equipped for complicated work inside teeth. Dentists tend to earn good money, though their student loans and overhead costs can be steep. Don't pursue dentistry if you're turned off by teeth, mouths, surgery, or micro-construction. Do consider dentistry if you want a hands-on medical specialty in a clean, well lighted workplace where your coworkers smile, emergency cases are rare, and nobody dies on the table.
By contrast, medical doctors first attend a 4-year general medical school, during which they learn about many specialties, then specialize by their choice of residency training. Depending on the specialty, residencies last 3-8 years. Different specialties offer a huge range of work conditions, challenges, and rewards, so if dentistry doesn't sound like your ticket then medical school probably has something for you.
