right lower second primary molar tooth

The right lower second primary molar is the most distal deciduous molar in the mandible, erupting around 20-30 months of age.

It is located at the distal end of the mandibular primary dentition on the right side, following the first primary molar.

It serves as a major grinding tooth for food breakdown and maintains space for the erupting permanent first molar.

It is supported by mandibular alveolar bone through the periodontal ligament and innervated by the inferior alveolar nerve.

Its retention ensures proper jaw development and appropriate positioning of the permanent first molar, which is critical for long-term occlusion.
