Teeth are an important part of people's lives. A scrutiny of the teeth structure and function is necessary for the public, as well as for pre-dental students going into dentistry. This paper contains the information necessary, in simplest terms, for understanding teeth structure, function, occlusion, and development patterns. The paper also depicts dental problems faced in today's society, such as tooth decay. Treatment options including root canal, crown, implant, dentures, orthodontics, and orthognathic surgery are also described. Having a basic understanding of how dental professionals treat dental problems will allow the general public to identify problems such as decay, teeth loss and malocclusion, and participate in the decision-making process regarding their dental health. It will also allow them to have a realistic expectation for the outcomes of these types of procedures.
