At birth people usually have 20 baby (primary) teeth, which start to come in (erupt) at about 6 months of age. They fall out (shed) at various times throughout childhood. By age 21, all 32 of the permanent teeth have usually erupted. Download the following eruption charts: Baby Teeth Eruption Chart (PDF) Permanent Teeth Eruption Chart (PDF)

Tooth eruption is a process in tooth development in which the teeth enter the mouth and become visible. It is currently believed that the periodontal ligament plays an important role in tooth eruption.

Feb 20, 2025 · Tooth eruption is the natural process in which teeth emerge through the gums and become visible in the mouth. This occurs in a specific sequence, beginning with the eruption of primary (baby) teeth in infancy, typically around six months of age, and continuing with the emergence of permanent teeth during childhood and adolescence.

This review focuses on human and other mammalian teeth with a time- and spacewise limited period of eruption and analyzes recent observations and experimental data on dogs, rats, primates, and humans in a framework of basic biological parameters to formulate a guiding theory of tooth eruption.

Why a tooth begins eruption and what enables it to move eruptively and later to end these eruptive movements is not known. Pathological eruption courses contribute to insight into the aetiology behind eruption. A new theory on the eruption mechanism is presented.
