Dentist

Who is a Dentist / Dental Surgeon ?

A dentist is a person who is licensed by the nation or state's licensing body to practice dentistry independently. He can either run a private practice or work as a government employee or an employee in other's clinic. A dentist can examine and diagnose the disease of your oral cavity, perform restorations, rectify maloccluded teeth by the use of removable and fixed orthodontic appliances, extract your tooth, provide partial or complete / removable dental prostheses, etc. The dentist deals not only with the teeth, the rest of the soft tissues like tongue, palate, buccal and labial mucosa are also dealt by the dentist. Extra-oral lesions, swellings, and tumors of the head and neck region too come to the attention of the dentist first. Some facial reconstruction surgeries, surgical correction of cleft lips and palates, implants,etc. all come under the duties of a dentist or dental surgeon.
