After England denied them a bid for successive Grand Slams last week, a sluggish Ireland looked at risk of relinquishing their grip on the title and giving the English something to play for in Paris after eking out an unconvincing 7-6 halftime lead.
Andy Farrell's men showed far more intent straight after the break, however, pushing hard until Andrew Porter's 65th-minute try put daylight between the sides, only for a late Huw Jones try and an Irish yellow card to set up a nervy finish.
The victory kept Ireland too far ahead of second-placed England, who play France in the final game of the championship later on Saturday (local time). Scotland finished with two wins and three losses.
