The tooth numbering continues by assigning teeth numbers descending to the lower left third molar (number 17) and follows the lower (mandibular) jaw up to the tooth farthest back on the bottom right side of the mouth (number 32).
Among deciduous (primary) teeth, ten are found in the maxilla (upper jaw) and ten in the mandible (lower jaw), for a total of 20. The dental formula for primary teeth is 2.1.0.22.1.0.2. In the primary set of teeth, there are two types of incisors â centrals and laterals, and two types of molars â first and second. All primary teeth are normally later replaced with their permanent counterparts.
