What is your specialty?
As a general dentist I do not, by default, have a specialty. However, there are some dental procedures that I have worked extra hard to become very proficient at in addition to routine dental work. I have taken advanced training with world renown instructors in cosmetic dentistry, occlusion (how your teeth bite and function together), and composite (tooth-colored filling material) artistry using advanced layering techniques. My goal is to provide my patients with restorative dental work that appears indistinguishable to natural teeth, to not only the patient but to other dentists. It's actually not too hard to make something that looks white and roughly the same shape as a tooth, but the artistic challenge to recreate natural beauty is very rewarding.
As an FYI there are nine recognized specialties by the American Dental Association (ADA):
Dental Public Health, Endodontics, Oral and Maxillofacial Pathology, Oral and Maxillofacial Radiology, Oral and Maxillofacial Surgery, Orthodontics and Dentofacial Orthopedics, Pediatric Dentistry, Periodontics, and Prosthodontics.
Nearly all of these specialties require additional schooling above and beyond dental school. Some even require a residency. Perhaps the most intensive training is for Oral and Maxillofacial Surgery where the specialist goes through dental school, medical school, and also a residency--that's a lot of schooling!
