Deciduous teeth first teeth seen in the mouth are the mandibular centrals and the last are the maxillary second molars. The primary teeth are made up of central incisors, lateral incisors, canines, first molars, and secondary molars; there is one in each quadrant, making a total of four of each tooth. All of these are gradually replaced with a permanent counterpart except for the primary first and second molars; they are replaced by premolars. The replacement of primary teeth begins around age six, when the permanent teeth start to appear in the mouth, resulting in mixed dentition. The erupting permanent teeth cause
Neonatal teeth decrease the likelihood of removing permanent tooth buds with the natal tooth. They should also not be removed if the infant has hypoprothrombinemia. In case of complications when the natal teeth need to be removed, dental radiographs should be obtained whenever possible, and evaluated and followed up with pediatric dentists. Neonatal teeth Natal teeth are teeth that are present above the gumline (have already erupted) at birth, and neonatal teeth are teeth that emerge through the gingiva during the first month of life (the neonatal period). The incidence of neonatal teeth varies considerably, between 1:700 and 1:30,000 depending on the
