England won a third straight ODI series in the Caribbean, after 2009 and 2014, but it's the first time it has swept the West Indies on its own turf.
Amid the harrowing second-innings collapse from the hosts that at one stage saw them 87 for eight came a moment of mild catharsis for Ben Stokes, who with his first ball to Carlos Brathwaite since the Bajan's six-hitting assault on him in the World Twenty20 final previous year managed to trap his old nemesis lbw.
Jonathan Carter provided some fearless resistance with his 46 but it would prove to be in vain as the West Indies floundered in the face of scoreboard pressure.
No England batsman before Hales has reached five one-day centuries quicker than his 39 innings and while it was chancy in parts - not least the top-edged six that brought up the milestone from 99 balls and prompted a fist-pumping roar from the 28-year-old - it also featured his trademark long-levered swats through leg.
Hales found the necessary momentum, largely by hitting Devendra Bishoo out of the attack.
His 110 here was his fifth ODI century but given the circumstances it may have felt even sweeter for Hales than the England-record 171 he bludgeoned against Pakistan at Trent Bridge last August.
Root's unbeaten 90 was pivotal in helping England recover from 124 for six to win the second match of this series in Antigua last Sunday.

Rivlin added: "The same appreciation goes to President Trump, who condemned the recent attacks. The visit also was meant to bolster economic ties between Israel and New York State.
Alzarri Joseph picked up 4 for 76 to be the pick of the West Indies bowlers.
"That's down the to the selectors in terms of picking the team for that match".
But he speared in a delivery that hit Brathwaite on the pads and, after a review by England, Stokes had his man lbw as the hosts limped to 75 for seven in their forlorn chase.
When Carter was the ninth wicket to fall to Steven Finn (2-35 from 10), a late flurry from number 11 Joseph (22 not out) did add a glimmer of respectability to the home side's score.
So it was perhaps some kind of comfort to Stokes that he dismissed Brathwaite with his first delivery to him since that epic finale in India.
Kieran Powell looped a catch to square leg off the fourth ball of the innings, Evin Lewis gave a soft caught-and-bowled to Chris Woakes for a duck in the next over, and Kraigg Brathwaite gave Woakes another wicket in the fourth over.
