I would like to place a bullet in the same way that $\dot{x}$ places a dot above x. Does anyone have a clue?

Another clear case for the accents package: output.

\documentclass{article}
\usepackage{accents}
\begin{document}
$\accentset{\bullet}{x}$
\end{document}

Note that, in contrast to \overset, the slant of the letters is taken care of automatically:

Here you go:

enter image description here

\documentclass{article}
\usepackage{amsmath}

\begin{document}
$A \overset{\bullet}{B} C$
\end{document}

  • It would be worth editing your question to clarify, then, as that's the first thing everyone will see when they click this thread. – ach May 22 '13 at 10:52

I used the \; to add some horizontal space before the bullet, to account for the fact that the under-letter will be set in italic which is generally slanted:

\documentclass{article}
\usepackage{amsmath}

\begin{document}
\[
\overset{\;\bullet} B
\]
\end{document}
