Many Americans today enjoy excellent oral health and are keeping their natural teeth throughout their lives. But this is not the case for everyone. Cavities are still the most prevalent chronic disease of childhood.
Too many people mistakenly believe that they need to see a dentist only if they are in pain or think something is wrong, but they're missing the bigger picture. A dental visit means being examined by a doctor of oral health capable of diagnosing and treating conditions that can range from routine to extremely complex.
The team approach to dentistry promotes continuity of care that is comprehensive, convenient, cost effective and efficient. Members of the team include dental assistants, lab technicians and dental hygienists. Leading the team is the dentist, a doctor specializing in oral health who has earned either a Doctor of Dental Medicine (DMD) degree or a Doctor of Dental Surgery (DDS) degree, which are essentially the same.
Dentists are doctors who specialize in oral health. Their responsibilities include:
Dentists' oversight of the clinical team is critical to ensuring safe and effective oral care. Even seemingly routine procedures such as tooth extractions, preparing and placing fillings or administering anesthetics carry potential risks of complications such as infection, temporary or even permanent nerve damage, prolonged bleeding, hematomas and pain.
Dentists' areas of care include not only their patients' teeth and gums but also the muscles of the head, neck and jaw, the tongue, salivary glands, the nervous system of the head and neck and other areas. During a comprehensive exam, dentists examine the teeth and gums, but they also look for lumps, swellings, discolorations, ulcerations — any abnormality. When appropriate, they perform procedures such as biopsies, diagnostic tests for chronic or infectious diseases, salivary gland function, and screening tests for oral cancer.
In addition, dentists can spot early warning signs in the mouth that may indicate disease elsewhere in the body. Dentists' training also enables them to recognize situations that warrant referring patients for care by dental specialists or physicians.
The level of education and clinical training required to earn a dental degree, and the high academic standards of dental schools, are on par with those of medical schools and are essential to preparing dentists for the safe and effective practice of modern oral health care.
Most dental students have earned Bachelor of Science degrees or their equivalent, and all have passed rigorous admission examinations.
The curricula during the first two years of dental and medical schools are essentially the same — students must complete such biomedical science courses as anatomy, biochemistry, physiology, microbiology, immunology and pathology. During the second two years, dental students' coursework focuses on clinical practice — diagnosing and treating oral diseases. After earning their undergraduate and dental degrees (eight years for most) many dentists continue their education and training. Some go on to achieve certification in one of nine recognized dental specialties.
Upon completing their training, dentists must pass both a rigorous national written examination and a state or regional clinical licensing exam in order to practice. As a condition of licensure, they must meet continuing education requirements for the remainder of their careers, to keep them up-to-date on the latest scientific and clinical developments.
A career as a dental hygienist offers a wide range of challenges. In the dental office, the dentist and the dental hygienist work together to meet the oral health needs of patients. Since each state has its own specific regulations regarding their responsibilities, the range of services performed by hygienists varies from state to state. Some of the services provided by dental hygienists may include:
Dental assistants greatly increase the efficiency of the dentist in the delivery of quality oral health care and are valuable members of the dental care team. If you have strong communication skills, enjoy working with your hands as well as your mind and want a career with responsibility, dental assisting is for you.
The duties of a dental assistant are among the most comprehensive and varied in the dental office. The dental assistant performs many tasks requiring both interpersonal and technical skills. Although state regulations vary, responsibilities may include:
