We estimate pionic decay widths of the narrow charm-strange resonances ${D}_{sj}(2317)$ and ${D}_{sj}(2460)$ using the $^{3}P_{0}$ model. Their one-pion decays occur through $\ensuremath{\eta}\ensuremath{-}{\ensuremath{\pi}}^{0}$ mixing while the two-pion decays of ${D}_{sj}(2460)$ occur through the virtual ${f}_{0}(980)$ meson. The mixing between $^{3}P_{0}$ and $^{1}P_{1}$ states enhances the single-pion decay width of ${D}_{sj}(2460)$ and suppresses its double-pion decay width significantly. As a byproduct, we also calculate pionic decay widths of ${B}_{sj}(5765)$, ${B}_{sj}(5765)$ mesons in the $({0}^{+},{1}^{+})$ heavy doublet.
