Primary teeth that are shed and replaced by permanent teeth are called______teeth.
Choose Your Answer:
deciduous
non-deciduous
non-succadaneous
non-exfoliating
The correct answer and explanation is:
The correct answer is deciduous teeth.
Deciduous teeth are commonly known as “baby teeth” or “milk teeth.” These are the first set of teeth that humans grow, usually beginning around six months of age. There are typically 20 deciduous teeth, which include incisors, canines, and molars. These teeth serve as placeholders for the permanent teeth that will come later.
Deciduous teeth start to fall out at around age six, and this process continues until about age 12. The shedding of these teeth is called exfoliation, and they are gradually replaced by the permanent teeth. This transition is crucial for the development of a full set of permanent teeth, which are meant to last for most of a person’s life.
The term “deciduous” refers to the natural process of shedding, much like how leaves fall off trees each year. These teeth are important for several reasons: they allow a child to chew food properly, they help with speech development, and they maintain the space needed for the adult teeth to emerge properly. The loss of deciduous teeth makes way for the permanent teeth, which are larger and more durable.
The other terms listed are incorrect in this context:
- Non-deciduous teeth would refer to permanent teeth, which are not shed and replaced.
- Non-succadaneous teeth are not the term used in dental anatomy; this term would be confusing.
- Non-exfoliating is not used to describe teeth in the dental context.
Thus, deciduous teeth are essential in a child’s oral development and their replacement marks a major step in their growth.
