Tooth Eruption Process in Humans

Tooth Eruption Process

Tooth eruption in humans is a fascinating process that involves both deciduous (baby) teeth and permanent teeth.

Deciduous teeth, also known as baby teeth or milk teeth, typically start to appear around six months of age and continue to emerge until about the age of three. These primary teeth serve as placeholders for the permanent teeth that will eventually replace them.

Permanent teeth begin to replace deciduous teeth around the age of six, starting with the lower central incisors and upper central incisors. Over the following years, the rest of the permanent teeth, including premolars, canines, and molars, will gradually emerge.

Specifically, about tooth J and tooth K:

Tooth J refers to a primary lower right second molar in deciduous dentition.

Tooth K would be its permanent successor, the lower right second premolar.

Therefore, the succedaneous tooth that erupts beneath tooth J is tooth K, marking an important transition in the dental development of an individual.

It's important to note that wisdom teeth, the third molars, usually emerge in the late teenage years or early twenties, completing the set of 32 permanent teeth in adulthood.
