Slicing problem

[Killrob]

Hi all,
i have a slicing problem
i use Amazonbasic PLA Withe Pearl with 0.4 nozzle and 0.2 layer
in first image you can see the STL before slicing, the second one is post slicing, as you can see there is a problem with upper teeth, in STL they are solid with restof the body, in the sliced one there is a gap, and i don’t know witch paramenter i have to change.
Any help would be appreciated.
TY all

Would it be convenient for you to provide the STL file or the 3MF file?

here you are
LED_Skull.stl (1,5 MB)
LED_Skull.3mf (7,7 MB)
both files

the model has non-manifold errors. Please fix the model and then slice it.
