In this letter, we first investigate the gravity localization and mass spectrum of gravity KK modes on de Sitter and anti-de Sitter thick branes. Then, the effective Newtonian gravitational potentials for these bent branes are discussed by two typical examples. The corrections of the Newtonian potential turn out to be ΔU(r)∼1/r2 at small r for both cases. These corrections are very different from that of the Randall-Sundrum brane model ΔU(r)∼1/r3.
