"Everything is going to be just fine guys, I promise," Dempster said on "The Waddle & Silvy Show" on ESPN 1000. "There's a pretty good chance we we'll have a two-game losing streak at some point this season again."
Dempster said there's an easy way to calm fans who are seeing some of the same problems they witnessed last season, including an ineffective bullpen. Dempster left with a 2-1 lead Wednesday after throwing six strong innings, but the 'pen surrendered two in the eighth -- on a Chipper Jones home run -- in a 3-2 loss.
"We can put an end to that [fan reaction] real quick by going out and winning a bunch of ballgames," Dempster said. "Winning cures everything.
"Everybody wants to dwell on the past, whether it's yesterday or the last pitch, and you can't do that. You can't control yesterday and tomorrow may not come, so let's enjoy the present. I think if we take that philosophy as players, and even as fans, we'll have a really good season. We have a good team. We lost two games to start the year, and everything will be just fine and we'll get back on the winning track today."
Wells won 12 games as a rookie last year, and he was often the pitcher to turn things around when the team struggled.
"[He] didn't just catch lightning in a bottle, where he's going out and overpowering guys," Dempster said. "He knows how to pitch.
"He's got a real good game plan, works hard, keeps the ball down and makes adjustments really fast. You talk about guys having the sophomore slump, he's going to go out there and continue to do exactly what he did last year."
Dempster said he hasn't lost faith in his bullpen, which was one of the Cubs' biggest question marks entering the season.
"I always feel comfortable handing the ball to the guys in the bullpen," Dempster said. "And that's what Chipper Jones does. You can't make too many mistakes. He made us pay and hit a two-run home run, and we walked away losers.
"But we'll right back in there today and go out there and win a game on get-away day."
