Dentistry a branch of medicine dealing with the functioning, pathology and treatment of teeth, periodontium, tongue, mucous membrane and other tissues of the oral cavity and its surroundings, as well as the human temporomandibular joint.

We distinguish:
- conservative dentistry
- endodontics (root canal treatment)
- dental surgery
- maxillofacial surgery
- orthodontics
- periodontics
- prosthetics
- pedodontics (children's dentistry).

A dentist and/or hygienist also deals with prophylaxis, and check-up visits to the dentist's office should take place at least once a year.
