Dele Alli scored his first league goal in 17 months and Harry Kane made his long-awaited return from his extended summer break as Tottenham maintained their 100% start to the season at Wolves.
Alli's ninth-minute penalty proved enough to separate the sides in a breathless encounter at Molineux.
Roared on by an enthusiastic crowd, Wolves were unlucky not to come away with a point.
The dangerous Adama Traore wasted the best of a succession of chances for the hosts when he was sent through by Ruben Neves, only to shoot straight at Hugo Lloris.
Tottenham, though, could justifiably argue they could have won by more.
Wolves keeper Jose Sa made four excellent second-half saves, including one to deny Kane a comeback goal.
It was a day to remember for new Spurs boss Nuno Espirito Santo, who was a hugely popular figure in his four years as Wolves boss before leaving in the summer. Now he appears to be bringing some stability back to a club that appeared in chaos for the last few months.
