The tooth on the left has an “s” type curve in it an the one on the right is more “c” shaped (the crown). Does that make a difference in the genus?

The blade on the second one is flatter & wider, and the cusps shorter/stouter. Not sure about this one. 'Those who cannot remember the past are condemned to repeat it.'
