If anyone wants to know it's just Freestyle set to the size of 1 in the render tab and 1 in the line style thickness tab and it's just the contour and edgemark (teeth were highlighted with edge, isn't good when you can see the back edge) and there's two render layers, one that's just the usual render layer without freestyle and one that's just freestyle. Then in the compositor the freestyle lines' alpha is used as the fac for a mix node that softlights black onto the other render layer, and to handle the bright areas the non-freestyle render layer is sent to a black and white converter and inverted and then the constrast is boosted with curves so that only the bright areas become black and everything else is white or near white, and then that's sent to a mix node set to multiply with the other freestyle softlight mix node and the freestyle render layer's alpha is used as the fac. Maybe a color ramp on the inverted image to control how dark the lines end up.
