Dental Care is the practice of keeping one’s mouth clean and free of disease and other problems (e.g. bad breath) by regular brushing and cleaning between the teeth. It is important that oral hygiene be carried out on a regular basis to enable prevention of dental disease. The most common types of dental disease are tooth decay (cavities, dental caries) and gum diseases, including gingivitis, and periodontitis.Regular brushing consists of brushing twice a day: after breakfast and before going to bed. Cleaning between the teeth is called interdental cleaning and is as important as tooth brushing.This is because a toothbrush cannot reach between the teeth and therefore only cleans 50% of the surfaces. There are many tools to clean between the teeth, including floss, flossettes, and interdental brushes. It is up to each individual to choose which tool he or she prefers to use. Oral and maxillofacial surgery (OMS or OMFS) specializes in treating many diseases, injuries and defects in the head, neck, face, jaws and the hard and soft tissues of the oral (mouth) and maxillofacial (jaws and face) region. It is an internationally recognized surgical specialty. In countries such as the UK, Australia and most of Europe, it is recognized as both a specialty of medicine and dentistry, and a dual degree in medicine and dentistry is compulsory. In other countries including the United States, India, Canada, Brazil, Sweden and Israel, it is a recognized specialty of dentistry.Dentistry is a branch of medicine that consists of the study, diagnosis, prevention, and treatment of diseases, disorders and conditions of the oral cavity, commonly in the dentition but also the oral mucosa, and of adjacent and related structures and tissues, particularly in the maxillofacial (jaw and facial) area.Although primarily associated with teeth among the general public, the field of dentistry or dental medicine is not limited to teeth but includes other aspects of the craniofacial complex including the temperomandibular and other supporting structures.
