Page "Amphibian" Paragraph 93
from
Wikipedia
Amphibians usually swallow food whole but may chew it lightly first in order to subdue it.
They typically have small hinged pedicellate teeth, a feature unique to amphibians.
The base and crown of these are composed of dentine separated by an uncalcified layer and they are replaced at intervals.
Salamanders, caecilians and some frogs have one or two rows of teeth in both jaws but some frogs ( Rana spp.
) lack teeth in the lower jaw and toads ( Bufo spp.
) have no teeth.
In many amphibians there are also vomerine teeth attached to a facial bone in the roof of the mouth.
