The effects of charmed meson loops on the spectrum of charmonium are considered, with special attention paid to the levels above open-charm threshold. It is found that the coupling to charmed mesons generates a structure at the $D{\overline{D}}^{*}$ threshold in the ${1}^{++}$ partial wave. The implications for the nature of the $X(3872)$ state are discussed.
