A few days ago, our toilet overflowed (clean water only) and the water reached our hallway, which has our Armstrong laminate floors.

The water traveled underneath the wood laminate (probably only a three foot by four foot area) to soak the carpets in the entryways of two bedrooms. There was no moisture or water visible on top of the laminate but clearly there was underneath.

Now four days later, there's minimal signs of damage (very slight rising on ends of a couple of boards- if you didn't know, you wouldn't notice). My main concern is unlike the carpets, we can't lift up laminate to dry it out - the floor is on a concrete slab. We're worried we might have mold underneath. Can we leave this alone? Or is this something we should still worry about because of possible mold?
