In recent years tetraquark and pentaquark states have received much attention due to the significant experimental findings. In this work masses of some heavy tetraquarks are estimated by considering the spin-spin interaction, the dipole-dipole interaction, and the meson-meson interaction. It is found that such interactions give significant mass contributions. The Regge trajectory of X(3872) state is also studied and is found to be non-linear. Masses of some tetraquark states are also proposed.
