The two-time defending champion remained nine points ahead of Roma, which drew 0-0 at bitter rival Lazio in the capital derby. Roma has a match in hand on Juventus after last week's game against Parma was called off due to a waterlogged pitch.
"It's not good enough to dominate for 45 minutes, seeing as the slightest lack of concentration can make everything in vain," Juventus coach Antonio Conte said. "We let them back into the game... it was unacceptable. A lost chance.
"We're conceding a lot from deadball situations, we need to focus more. It's useless to study our opponents' tactics and then make mistakes like this." Carlos Tevez scored twice in the first half for Juventus to take his tally to 13 for the season.
But Luca Toni reinforced his bid for a World Cup spot when he reduced the deficit with his 11th goal in 20 matches and substitute Juanito Gomez Taleb, who only came on in the 86th minute, leveled deep in stoppage time.
Verona is fifth, three points ahead of Inter Milan which hosts Sassuolo later. "We drew against a great team and we are very happy with this point," Gomez said. "Safety remains our aim though, not qualifying for Europe. We're doing well."
