Dentistry may be the popular "practical application of knowledge of dental science (the science of position, design, purpose of teeth and their supporting bones and soft tissues) to human beings." I'm sure you can see why generally in most countries, a long time of education are needed in university in order to become an actual dentist. A dentist is what we call a professional practitioner of dentistry. This "Dentist" has normally examined between 4-8 years at university and will normally also provide alot of practical experience with focusing on actual people, sometimes accompianed by a more experienced dentist. 

There's nine different areas that are branched from dentistry which all require training after the initial dental school. These are: 

Dental Public Health - Which can be the research of social health procedures and dental epidemiology 

Endodontics - That will be root canal treatment 

Oral and Maxillofacial Pathology - Which will be the treatment of maxillofacial and oral connected illnesses the study, diagnosis, and often 

Oral and Maxillofacial Radiology - That will be the study and radiologic interpretation of oral and maxillofacial conditions 

Oral and Maxillofacial Surgery - Which can be the extractions and facial surgery 

Orthodontics - Which can be straightening of teeth 

Pedodontics - Which will be pediatric dentistry for children 

Periodontics - That is treatment of gum infection 

Prosthodontics - Which can be the replacement of missing facial composition by prostheses such as dentures, links and improvements 

Sometimes visiting the Dentis is an un-nerving situation. Rest assured that if you are likely to a qualified dentist, they have most of the instruction that is needed to perform what it's that you need. You should speak those around you and find out who has already established good and bad experiences and where, if you're still un-easy or having an issue selecting a dentist locally.
