Not a way I can think of. There is no online library of morphs. You could contact the author tell them the scene is broken and ask them what morphs they used.
Anyway the originating VARs for the morphs you are looking for should be:
AA Mouth Kiss 1:AshAuryn.AshAuryn_Sexpressions_2_Point_0.4.var
AA Mouth Kiss 7:AshAuryn.Assorted_Expressions_Pack_2.3.var
AA_L - Tongue 1:AshAuryn.Expressions.5.var
Teeth UpDown Upper

o_Not_Distribute.Import_Reloaded_Full_Addon.3.var
Teeth Upper Angle 02:kemenate.Morphs.10.var
Tongue+LowerJawOpen:QBase.AutoMorphsFromEasyMate.1.var
asco - Teeth Smile:ascorad.asco_Expressions.12.var
QDR Tongue Width:qdaro.Morphs.1.var
asco - Tongue Scream:ascorad.asco_Expressions.12.var
All these morphs are packed in morph collections. For 'teeth_bite' I couldn't find any morphs collection VARs and I could find it only in VAR scenes where the author added the morphs. For example BANANANA.WitchGirl_WAKARASE.1.var.
This is why you need a lot of VARs to search in. Some early morphs might never have been initially packaged to a VAR and are just standalone files that you add to your VAR. Also the descriptive text which we are searching with is not a singular signature for a morph. There is a chance different authors with different morphs could have named their morphs with the same name 'teeth_bite'.
