Sloths are related to anteaters, a group of mammals known as edentates
1. Lacking teeth.
2. Of or belonging to the order Edentata, which includes mammals having few or no teeth, such as anteaters, armadillos, and sloths.
Any of various mammals belonging to the order Xenarthra (or Edentata), having no front teeth and few or no back teeth. The lumbar vertebrae have extra
joints, which add support during digging. Sloths, armadillos, and anteaters are edentates.
Well that explains the teeth thing.
