Teeth is a Pixel shader available in all 
Source games. It is a shader for teeth that is used to dynamically adjust the brightness of the teeth based on how open the mouth is.
Note:This shader is likely obsolete, as Valve hasn't used it for any of their recent games. Instead, they include teeth on their facemaps, using the shader VertexLitGeneric.
Parameters
$clientshader "MouthShader"- Todo: What does this actually do?
$illumfactor
$forward
$bumpmap
$phongexponent
