Toyota sequoia bumper filler?

Stupid mistake on my part, I hit the wall in a parking garage in my 03' sequoia. The front bumper is ok but it seemed to to have shifted a bit from the body lines....the bumper filler got pitched and is now dented inwards under the grill which for the most part you cant really see. I want to know if this will all line up if i re-fit the bumper on the mounts and get a new filler? I hit the wall at about 3mph, all i can do is laugh about how stupid this whole situation was. I'm wondering if that is a significant impact in order to do some hidden damage under the bumper cover?
