Right Upper Second Secondary Molar Tooth (Dens molaris secundus maxillaris dexter)
Educational content only — not medical advice.
Anatomy
The right upper second secondary molar tooth (FDI #17, Universal #2), or 12-year molar, is situated posterior to the first permanent molar in the maxilla. Smaller than the first molar, it typically displays four cusps (with the distopalatal cusp noticeably reduced) and three roots that run closer together and parallel, functioning in heavy masticatory grinding.
Clinical notes
Its distal position in the dental arch can make plaque removal difficult, increasing susceptibility to interproximal decay and periodontal pocket formation around the roots near the maxillary tuberosity.
