Weaning and dental health

Tooth development begins at a very early stage in life with the initial stages being seen at about 28 d in utero and mineralization of primary teeth beginning well before birth at about 14 weeks in utero. Mineralization of permanent teeth starts later, at or just after the time of birth. The first tooth, usually a lower primary incisor, erupts at about 6 months of age, a time when weaning should have begun. Eruption continues in the months following, with the primary dentition being complete on average by the age of 2.5 years (Lunt & Law, 1974a, b).
