Torres came off the bench to score the second goal in the in the champions' 3-0 Barclays Premier League win over West Ham.
"It was a fantastic moment. It will help him move on quickly," said Ancelotti. "I think that the bad moment is gone and now his future will be fantastic here, at this club with his team-mates."
The Blues boss added: "He needed to score to move from this moment. He scored and the next game will be, for him, really better."
Ancelotti would have feared the worst when the ball got stuck in the mud and he added: "He was unlucky there but it was fantastic to move quickly, to come back and to shoot well."
Torres had been relegated to the bench for three successive games, with Didier Drogba's vastly superior form impossible to ignore. The pair have failed to strike up an understanding when they have played together but Ancelotti hinted he might field both against Tottenham next week.
"Considering the performance of Didier, considering that Fernando scored, we have to try to put both together," he said. "We have one week to train, we can try and I think that I will take a decision for the next game."
A 3-0 defeat was harsh on West Ham, who ended the day back on the bottom of the table, albeit still two points from safety. The Hammers missed several chances to score and manager Avram Grant said: "I think everybody in this room knows that we deserved better.
"Petr Cech was excellent (with) two or three great saves. If someone didn't see the game, they think 3-0, Chelsea is much better than us.
"I can be very proud of the players. Without the player of the year (Scott Parker), without Matthew Upson, without Gary O'Neil, and Mark Noble second half, they showed a lot of belief, a lot of spirit."
