"The periodontal ligament (PDL) connects the tooth root to the underlying lamina dura, which itself is the cortical bone which lines the tooth socket. This joint between a tooth and alveolar bone is a fibrous joint called a dentoalveolar syndesmosis."
"The deciduous (primary) teeth start erupting at six months (lower central incisor) and are completely erupted by around 3 years of age. They are then progressively replaced by permanent (secondary) teeth from the age of six with the final eruption of the third molar between 18-24 years 5."

"The teeth (singular: tooth; collective term: dentition) can be both primary and secondary, with the eruption of permanent teeth occurring over a long period between the ages of 6 and 24 years. When an individual has a complete set of teeth, they are said to be dentate, if some are missing they are partially dentate. Complete absence of the teeth is termed edentulism, if only a few teeth are remaining then partial edentulism."
