I keep my guitars at 45% humidity, for all of them ( including my Les Pauls). It not only saves them from fret buzz or sharp edges, but from cracks due to the guitar shifting. Too much or too little humidity is a bad thing. So get a humidifier or dehumidifier, depending on where you live and the season. The other bonus, your instruments will stay in tune longer.
Living in western Canada, I have have seen my fair share of the damage that humidity can have. Take care of your girls!!!
