Polytechnics, also known as technical colleges, generally do not offer programs in dentistry or dental surgery. Dentistry and dental surgery are highly specialized fields that require extensive education and training, and are typically only offered at universities or dental schools To become a dentist, individuals must complete a rigorous educational program that typically includes a four-year undergraduate degree followed by four years of dental school. This program includes both classroom instruction and clinical training, and covers a wide range of subjects including anatomy, physiology, pharmacology, and dental procedures.
