I'm not an expert, but it seems to me that gear teeth should mesh 'rounded top-to-rounded top'.
Is this proper for an internal gear ... ? http://i1260.photobucket.com/albums/ii564/BitHead77/ring_teeth_zps3bxx8sjb.jpg

image is gone. Gears mesh by contact wit the sides of the teeth. An involute gear is specially shaped so there is no sliding between gear faces which lowers friction. So the shape of the top of the gear is not important as long as it does not collide with valley of the meshing gear.
