The girls were flown to a hospital following Wednesday's accident in which one lost all of her teeth.
The girls were riding around the partially wooded yard of a home in Hunterdon County when the go-cart plunged off the edge of a cliff and landed on a bank of the Raritan River.
Rescuers waded across the river from a nearby YMCA camp to help the girls, ages 16 and 17.
