We all know that a person responsible in pulling out our bad teeth when it is aching is our dentist. I remembered it clearly when I was young, our school dentist will let us open our mouth and make a big "ahhhh" until he sees everything what's inside our mouth.As I grow older, I realized the importance of the dentist's role in our oral health. He is there to diagnose and treat whatever oral problems we have, more so advising us on how to take care of our teeth and mouth through proper diet, brushing, flossing and using fluorides plus other related aspects of oral care. What are they doing?Dentists are trained to get rid of tooth decay, fill cavities, check x-rays, put protective plastic sealants on children's teeth, straighten and mend broken teeth. They also conduct corrective surgery on gums and treat gum diseases. They also extract teeth and create models and measurements for dentures to substitute missing teeth. They also direct anesthetics and prescribe antibiotics and other medicines. What are their tools for the job?Dentists utilize different equipment such as x-ray machines, drills, mouth mirrors, probes, forceps, brushes, scalpels, lasers, digital scanners and other computer technologies for dental care may also be utilized. Dentists wear masks, gloves and safety glasses to protect themselves and their patients from communicable diseases.How are they categorized? Dentists in private practice supervise various administrative responsibilities such as bookkeeping and purchasing equipment and dental supplies. They can hire and oversee skilled people like dental hygienists, dental assistants, dental laboratory technicians and receptionists.A lot of dentists are considered general practitioners where they are handling various dental needs. While other dentists practice in any of nine specialty areas, such as:1. Orthodontists - straighten teeth by applying pressure to the teeth with braces 2.
