Can particle board flooring in a mobile home go from swollen back to almost normal? - board

My father lives in a mobile home in 1998. Your air conditioning pipe clogged sewer and water penetrated into the linoleum floor for a while, until I realized the world was swollen. His unit was introduced by what is expected that a leak of water is no longer replaced. Now it is swollen particleboard should never again be replaced by something lower by new board of directors or dry? How big is an agreement?
