Primary dentition starts on the arrival of the mandibular central incisors, usually at eight months, and lasts until the first permanent molars appear in the mouth, usually at six years. [44] The primary teeth typically erupt in the following order: (1) central incisor, (2) lateral incisor, (3) first molar, (4) canine, and (5) second molar. [45]
First molars (4) at approximately 14 months; Canines (4) at approximately 18 months; Second molars (4) at approximately 2–3 years; Milk teeth tend to emerge sooner in females than in males. The exact pattern and initial starting times of teething appear to be hereditary. [10] When and how teeth appear in an infant has no bearing on the health ...
From the age of two-and-a-half until about six years, the deciduous teeth maintain stability, until a set of molars (also called “Six Year Molars”) appear in the lower jaw; these are the child’s first permanent teeth.
The duration of delay is around 0.2 to 0.9 years, with an average of 0.56 years when all types of clefts were accounted for. The lateral incisor on the cleft side was typically the most delayed. The type of cleft and the severity of the condition did not affect the duration of tooth eruption.
The dashes (-) in the formula are likewise not mathematical operators, but spacers, meaning "to": for instance the human formula is 2.1.2.2-3 2.1.2.2-3 meaning that people may have 2 or 3 molars on each side of each jaw. 'd' denotes deciduous teeth (i.e. milk or baby teeth); lower case also indicates temporary teeth.
