It really depends on how well your tile floor was grouted and sealed. But especially with it being on concrete, I wouldn't worry too much. If it was on wood subflooor on the other hand, I would be very concerned. My only concern at this point is whether or not you have a heat grid installed under the tile. As long as you don't have any heat grid under the tile, I would recommend putting down a layer of oil-dry (available at automotive stores) to absorb any residual moisture. Keep an eye on it for any mold development, but I really think you should be fine.
