noun, plural: baby teeth
This first set of teeth develops during the embryonic stage. These teeth are sometimes referred to as baby teeth or milk teeth since they erupt during infancy. In humans, the twenty primary teeth emerge in the mouth typically as follows:
- 4 Central incisors - 6-12 months
- 4 Lateral incisors - 9-16 months
- 4 Cuspids - 16-23 months
- 4 First molars - 13-19 months
- 4 Second molars - 22-33 months
These teeth are eventually replaced by permanent teeth by age of six.
