The science of teeth is an important field of study, and two terms are commonly used to refer to it: DENTISTRY and odontology. DENTISTRY is the practice of diagnosing, preventing, and treating diseases and conditions of the oral cavity, as well as the placement and restoration of dental prosthetics. Odontology is the scientific study of teeth, including their structure, development, and diseases. Both DENTISTRY and odontology are essential for maintaining good oral health.
