The American Dental Association (ADA) is a professional organization that represents dentists in the United States. It was founded in 1859 and is the world's largest and oldest national dental association. The ADA sets standards for the practice of dentistry, provides continuing education opportunities, and advocates for the public's oral health. Dental GPs are general practitioners who specialize in providing comprehensive dental care to patients. They diagnose and treat a variety of dental conditions, including cavities, gum disease, and tooth decay. They also provide preventive care, such as regular cleanings and fluoride treatments.
