Since the experimental discovery of the first tetraquarks in 2003, there has been a lot of excitement around this topic from the theoretical as well as the experimental side. We employ hadronic bound state equations, i.e., Bethe-Salpeter equations, to study the properties of these four-quark states. In this talk we will present a comprehensive overview of the mass spectra for hidden- and open-flavour four-quark states in the charmonium and bottomonium sector, as well as their internal structure.
