Help | how can i sculpt inside mesh?

Hi everyone, I sculpted a figure and now I want to sculpt the teeth, the tongue, and the pharynx…
I have no idea how I actually go through the figure into it, as we say you can do it in blender…, of course I looked for guides on the subject on YouTube and here in the forum and I didn’t find anything appropriate…
I would appreciate an answer as soon as possible so that I can continue with the sculpture
