# Bool tool leaves parts after slicing

How can I cut out the slice(bite) without leaving any teeths?

1. Select teeth
2. Select fish
3. Bool Tool - Slice
4. Delete the slice

I can't see any face orientation problems (shown in screenshot above) I tried before slicing:

• Deleting everything possible eg. rigs, poses, vertex groups
• Ctrl+A Apply - All transforms
• Shift+N Recalculate Normals

Similar problem though not solving my case: The difference boolean doesn't seem to work on a specific area

• I would say it is an issue of topology (too small or ugly after cut). Also try to use regular Boolean Modifier, because I'm not sure BooTool can use "Exact" solver. If you want to let us see your issue closer attach simplified blend. Use blend-exchange.com copy-paste given code into your Q. – vklidu Mar 1 at 17:32
• @vklidu Thank you, tried regular without success. Attached the simplified file 13MB. – 412p9wej Mar 1 at 18:17
