While attempting to learn a bit of sculpting in Blender 2.92, I ran into an ugly problem: tiny holes started appearing in my sculpture.
I learned that using the Grab brush/functionality in Sculpt Mode and holding Shift while going over the holes, closes them back up.
Now, I do not believe it is a perfect method, but it does work.
Thank you for checking out my Blender Note! I am by all means a beginner in Blender, so I do not feel qualified to label this post as a 'tip' or 'tutorial'. However, I decided to upload this note for myself, and hopefully it can be useful to others as well.
