Teeth problem in a body mod

[Reecoom]

hi there, i have a body mod that i downloaded many years ago that has a problem in the teeth. it is a mod that is more than 10 years old so the problem must be old and i could not find any information on how to fix it.  the teeth for some strange reason load the texture of the tongue on the teeth or so it seems. when trying to change teeth nothing happens. it is as if by default this assigned the texture of the tongue to the teeth. if anyone has any idea what could be, I can pass the file. helpme :f
