Agree on both posts above concerning the light meter.  Now you will need to remove the reflection from the teeth.  Somehow, this last image looks correct given the immediate conditions available.  There is quite a bit of blue present. 

You mentioned BB's beach light set for the scene.  Is this the original light set created for VSS?  If so, that light set was incorrectly created.  It is initially way too bright.  My suggestion, delete the light set and recreate it using 1 infinite light and IDL.
