Dentistry is the branch of medicine that is involved in the study, diagnosis, prevention, and treatment of diseases, disorders and conditions of the oral cavity, maxillofacial area and the adjacent and associated structures and their impact on the human body. Dentistry is widely considered necessary for complete overall health. Doctors who practice dentistry are known as dentists. The dentist's supporting team – which includes dental assistants, dental hygienists, dental technicians, and dental therapists – aids in providing oral health services.  

Dentistry usually encompasses very important practices related to the oral cavity. Oral diseases are major public health problems due to their high incidence and prevalence across the globe with the disadvantaged affected more than other socio-economic groups.   The majority of dental treatments are carried out to prevent or treat the two most common oral diseases which are dental caries (tooth decay) and periodontal disease (gum disease or pyorrhea). Common treatments involve the restoration of teeth as a treatment for dental caries (fillings), extraction or surgical removal of teeth which cannot be restored, scaling of teeth to treat periodontal problems and endodontic root canal endodontic treatment to treat abscessed teeth.  

Just over a quarter (26 per cent) of adults say the type of dental treatment they chose in the past has been affected by the cost of the treatment. And almost a fifth (19 per cent) said that they have delayed dental treatment for the same reason, according to a major survey published today.   

The Executive Summary of the 2009 Adult Dental Health Survey shows that adults' dental health continues to improve over time and that whilst the large majority of adults who tried to get an NHS dental appointment in the three years prior to being interviewed successfully made and attended the appointment, accessing NHS dental services remained difficult for a small minority.   

The findings show that, overall, half (50 per cent) of all adults with at least one natural tooth ('dentate') reported that they attended the dentist at least once every six months, 21 per cent indicated that they attended at least once a year, and a further 6 per cent once every two years.  

"The results of the survey give a clear picture of improving oral health amongst adults in England, Wales and Northern Ireland. Nearly four out of five adults (78 per cent) told us they had been given advice by a dentist or a member of the dental team on cleaning their teeth and gums. And three quarters of adults surveyed cleaned their teeth at least twice a day."
