Cause of scales missing on bottom of mouth

[Fall guys]

hi guys... me again ,

Has anyone had a problem with a patch of scales randomly disappearing from the bottom of a snakes mouth?



She has recently had a shed about 3 days ago and it was fine, humidity is fine, temp is fine, nothing "sharp" she could have scratched it on to cause scales to come off.

I have looked and can't find anything like it besides potentially being scale rot but doesn't really look like it..

Is it something I should be worrying about?

Doesn't really look too bad but knock on wood ;(

Thanks guys
