A dentist, also called a dental hygienist, is a dentist who specializes in the diagnosis, treatment, and prevention of dental conditions and diseases of the oral cavity, especially the teeth. The dentist’s support staff helps in giving personal dental care. They include the patient’s family members and closest friends, a registered dental practitioner, an assistant to the dentist, a pharmacy technician, a receptionist, and an office manager.

To practice dentistry successfully, one needs to have a four years of undergraduate study and a two years of dental school. After graduation, one needs at least two years of professional experience and a year of residency in a recognized dental facility. Dentists also complete a year of education at an additional fee. After gaining experience and completing all the requirements, a dentist can apply for a license to practice dentistry in a particular state. This process involves passing the state board exam and getting a certificate of dental surgery.
A dentist is supposed to use modern techniques in performing dental procedures. One such procedure that is followed by most dentists is the procedure of root canal therapy. In this procedure, the root canal therapists or the dentists remove the decayed or damaged tooth or teeth cavity of the patient. After the removal of teeth cavity, the dentist drills into the gums to expose the nerve endings. For gum infections, antibiotics are usually given intravenously before the dentist removes the infected gums with surgical instruments.
