Svechnikov extended it to 2-0 at 4:58 of the second period on a power play, scoring on a wrist shot from the left face-off circle that went in off the left post.
Teravainen made it 3-0 at 11:55 on the man-advantage when Seth Jarvis received the puck at the left post from Kotkaniemi, spun around and whiffed, allowing the puck to slide to Teravainen at the right post.
"Special teams obviously played a pretty large role," Panthers forward Eric Staal said. "They were good, and we need to be better in that area. It was a tough night for us."
Kotkaniemi made it 4-0 at 3:50 of the third period with a wrist shot from between the circles five seconds after a power play ended.
Florida was held to a season-low 19 shots and was outshot 12-3 in the first period, including a 14:15 stretch without a shot on goal. Raanta made 11 saves in the second, including a glove save on forward Sam Bennett's shot from between the circles at 6:24.
"'Rants' had some tough saves tonight," Brind'Amour said. "It just settles the whole group when you're out there and you're messing up and the goalie makes the save. You're not talking about it. He was good tonight."
