Dentistry is the field of medicine that focuses on the teeth, gums, and mouth. Dentists provide a variety of services, including preventive care, such as cleanings and fluoride treatments, restorative care, such as fillings and crowns, and cosmetic care, such as teeth whitening and veneers. To become a dentist, one must complete a bachelor's degree, followed by four years of dental school. After graduating from dental school, dentists must pass a national board exam and obtain a license to practice in their state.
The importance of dentists cannot be overstated. They play a vital role in maintaining the oral health of individuals and communities. Dentists can help prevent tooth decay, gum disease, and other oral health problems. They can also diagnose and treat oral diseases, such as oral cancer. In addition, dentists can provide cosmetic services that can improve the appearance of teeth and gums.
