Abstract: In this work we use an effective field theory (EFT) approach to study the $X(3872)$ resonance, assuming a heavy meson-heavy antimeson molecule as itsinner structure. From this EFT we extract some direct consequences for the hidden charm and bottom hadronic spectrum.Within this EFT we also study the decay $X(3872) \to D^{0}\bar{D}^{0} \pi^{0}$. This decay is unique since it is more sensitive to the long-distance part of the $X(3872)$ wave function than the $X(3872)\to J/\psi \pi\pi$ and $X(3872)\to J/\psi \pi\pi\pi$ modes. We also show that the possible $D\bar{D}$ Final State Interactions (FSI) effects can lead to experimental constrains on the Low Energy Constants (LECs) that appear in the EFT and the possible existence of a loosely $D\bar{D}$ bound state.
