The 2009 runner-up needed just 71 minutes to post a 6-0 6-1 6-1 victory and set up a last-32 clash against either qualifier Tobias Kamke of Germany or Spain's 29th seed Albert Montanes.
So far in the tournament the fifth seed has conceded just seven games after his first round defeat of Laurent Recouderc.
Dent finally registered on the scoreboard when he held serve early in the second set but he had no answer to the baseline power of Soderling who powered on to victory.
