Looks like you used a brush without back face masking and then re-dynameshed.
Basically your brush is sucking up the geometry from the other side of your mesh making it paper thin.

Under: Brush < Auto Masking < Backfacemask should solve your problem. You have to apply back face masking for each brush you use, it doesn’t apply to all your brushes at once.<auto masking<backfacemask="" should="" solve="" your="" problem.="" you="" have="" to="" re-apply="" back="" face="" masking="" any="" new="" brush="" you’re="" using,="" it="" doesn’t="" turn="" on="" for="" all="" brushes="" at="" once.<="" html=""></auto>


I recently had a problem with dynamesh that was similar to this. I was sculpting fan art of a character when this happened with dynamesh. I don’t know what happened, but I do know how to correct it.
In the Tools tab, go down to Geometry and open Modify Topology. Click Optimize Points. Next time you dynamesh, it should be gone.

Fixing the Backfacemask worked great

thank you so very much!

I have had this problem a few times but don’t always realise until I’ve done a bunch of other work so I don’t want to undo back to before I did this to fix it. What is the best way to patch these holes up?

I tried using the clay build up brush but it never closed it off.
