What happens if you exceed max takeoff weight?

Operating over weight will cause the aircraft to not meet the climb rates published in POH/AFM data, require longer runway distance for takeoff, lessen single-engine performance in a multi-engine aircraft, reduce glide distance in an emergency, and contribute to poor stablity if a stall is encountered, potentially ...

In the rare instances where dumping fuel becomes necessary, there are procedures that are supposed to be followed.
