# A metric space with a countable dense subset removed is totally disconnected?

I am wondering if it is true, and what the proof would go like, that given a metric space $X$ with a countable dense subset $D$, $\ X\setminus D$ is totally disconnected.

But $\Bbb R$ with any dense subset removed will be totally disconnected. –  Stefan Hamcke Feb 10 at 21:47
This is not true. $\mathbb Q^2\subset\mathbb R^2$ is dense, but in fact $\mathbb R^2\setminus\mathbb Q^2$ is path connected.
