If you're wondering which kind of career is going to be best for you, you should think about dental training. You don't have to be a fully qualified dentist to develop a dental career. Medical and dental services are those least hit by any weakness of the US economy and that includes dental assistants and other supporting roles that require less training.
It takes a lot of hard work and dedication to become a fully qualified dentist or orthodontist but the subject is interesting and challenging as well as rewarding. Training is essential to work at any level of dentistry. On a dental training program you can qualify to work in any of the various aspects of the dental services. At the highest level, you can study to be a Doctor in Dental Surgery (DDS), or, with less training, you can qualify to be a dental administrative assistant, dental laboratory assistant or dental hygienist. Alternatively, you can study orthodontics, take a program in International Dental Studies (IDS) or an Advanced Education in General Dentistry (AEGD). Each of these programs qualifies you for different kinds of work and requires a different level of input and achievement. You should find out what is involved in each type of program and what it will qualify you to do before you enroll.
