While sculpting a hand dyntopo stopped working after I unionized the last Finger to the hand. It worked for the first four, but after the last it didn't. It shows that it is activated, but it just doesn't add new geometry. I already checked for geometry inside the mesh after the union, but there isn't any. Anyone got an idea, why it is not working?

2$\begingroup$ have you set your geometry addition size low enough for new geometry? is it doing anything? Picture? $\endgroup$– dave44Mar 3, 2020 at 17:09

1$\begingroup$ You can try to make a new default scene and append your dyntopo mesh into it - could help, perhaps? $\endgroup$– Manu JärvinenMar 3, 2020 at 17:15

$\begingroup$ @dave44 Don't know how I can add an picture to a comment, but mydyntopo is set to relative detail, but it doesn't matter how close I am or how low my Detail size is, it doesn't add topology. $\endgroup$– SudragoMar 3, 2020 at 17:37

$\begingroup$ @ManuJärvinen I don't exactly know how I do that, but I tried to copy all objects into a new project and there it works without any problem. So it seems to be a problem with the project and not with my mesh $\endgroup$– SudragoMar 3, 2020 at 17:39

If anyone is still having this problem, the way I fixed it is to use the Snake Hook Brush. Make sure Dyntopo is enabled, and then just press wherever you need to make the mesh denser. There's no need to actually pull anything around – just tap and it subdivides it all. Hope this helps at least someone.

Here's a way of resetting the interface (including sculpt tools) while leaving the actual model alone. There are a lot of tools and options (A LOT) with sculpt mode, and sometimes it's easier to just reset everything to factory mode like when you created a new model, but without actually opening a new file.
As of Blender 2.92, go to the Edit→Prefrences menu. Make sure you're on the Interface tab. In the bottom left corner of the window, there is a hamburger icon. Click on it, and select "Load Factory Preferences".
This is an important last-resort move to know when your interface has gotten too out-of-hand to correct manually.
As a caveat, though, this also resets some system preferences, like switching your Cycles render device from CUDA or OptiX back to None (CPU only). This is an infrequent enough thing, and easy enough to fix, that having to change it back each time doesn't bother me so much.

Dyntopo doesn't work with the Draw (sharp) brush or any elastic deformation brushes (except if you're smoothing).
Try using the normal Draw brush, decreasing your detail size or changing to another brush.

I had this same problem. Try checking Refine Method. If it is set to Collapse Edges it can only make a mesh less detailed, you therefore have to swap it to Subdivide Edges or Subdivide Collapse. I believe Subdivide Collapse is the standard setting, but it got changed by accident.
