i had same kind of problem in my M800's front bumper [Black one, not the body colored] and some portion was gone inside. When I checked with MASS they said the entire bumper has to be replaced.
When I checked with local workshop guys they did it in Rs.200. Simply removed the bumper. Heated it with some tool and pushed it from inside. Tatadang. it came to normal shape without any damage.
So I suggest the decision you have taken for that small dent is right.
