Partula dentifera was a tree snail species endemic to Raiatea in the Society Islands. It was last seen alive in 1972; there were no further surveys within its range until 1991 by which time only empty shells could be found. Its extinction can be attributed to the carnivorous Rosy Wolfsnail (Euglandina rosea) which was introduced in the late 1980s. Living animals previously thought to be this species were found in 1991-2 and bred in captivity, but these are actually P. navigatoria. Partula dentifera is assessed as Extinct.

This species was endemic to Raiatea, Society Islands.

There are no populations of this species remaining.

This species was found on trees in forest habitats.

The extinction of this species is attributed to predation from the introduced carnivorous Rosy Wolfsnail (Euglandina rosea).

Many partulids were used in necklace making but no trade was recorded in this species.

This species was thought to be present in the Partula conservation breeding programme, but this was a misidentification of P. navigatoria.
