Becoming a dentist is a fairly arduous process. First, you'll have to complete a bachelor's degree in a subject like chemistry or biology. You then have to earn a DDS or DMD degree (the two are essentially identical) at dental school, which generally takes four years.
It's very tough to pass selection, and the national and state licensing exams are very hard. If that weren't enough, dental school in the United states generally costs about $50,000 per year! The good news is that you can take either your undergraduate degree, postgraduate dentistry studies, or both in Europe for a fraction of the cost, in English and using modern facilities.
Good dentists have excellent people skills, make people (including children) feel at ease, and have a knack for paying attention to details. They typically love science, enjoy helping people, and have excellent manual dexterity.
Other, related careers that don't require as high a degree of education include oral hygienists, dental assistants, and dental laboratory technicians. Qualified dentists may also specialize in a number of fields, such as oral and maxillofacial surgery and periodontics.
