When I Had to shut off the cold and hot water now it is turned back on but doesn't work in all faucets?

Very often when the water is shut off and turned back on, mineral deposits come loose and plug the screen in the faucet spout. That's the first place to look. It may be in the faucet itself. If neither side works, look at the spout, if it is only one side, check the side that isn't working.
