Final answer:
Deciduous teeth emerge during infancy, permanent teeth replace them in childhood and adolescence, and wisdom teeth typically erupt in early adulthood but may remain impacted, necessitating orthodontic surgery.
Step-by-step explanation:
The question seems to imply that the student is asking for information related to the development and treatment of teeth, specifically about proper procedures in handling extracted teeth. In dental health, it is important to know that deciduous teeth, also known as baby teeth, typically emerge during infancy. Permanent teeth will replace them as a person grows into childhood and reaches adolescence. Lastly, wisdom teeth are the final set of molars to emerge, usually during early adulthood. It is not uncommon for wisdom teeth to remain impacted and not erupt properly, in which case they are often removed through orthodontic surgery. The original passage describes a dental procedure where a spot of caries on an incisor needs to be filled, a process which can be painful and requires great care, especially when dealing with apprehensive patients.
