Question 40-Minute Layover at HEL: Is It Enough?

We're flying from DFW to HEL and only have a 40-minute layover. We won't have any checked bags, which should help, but I'm curious if that's enough time to make our connecting flight? Has anyone experienced a similar situation at Helsinki Airport? How was the process, and did you make your connection without a hitch? Any tips for navigating tight layovers would be super helpful!
