We analyse the IR singularities that appear in a noncommutative scalar quantum field theory. We demonstrate, with the help of the effective action and an appropriate field redefinition, that no IR singularities appear in the quadratic part at one-loop order. No new degrees of freedom are needed to describe the UV/IR mixing.
