In brief: See below
It's not necessarily bad, but it can be a sign of obstructed airways in the nose, obstructing tonsils or adenoids or other serious health issues.
It can also lead to dry mouth, gum disease and decay. If you have issues with snoring or stopping breathing while sleeping, you may have sleep apnea that could be due to obstruction and mouth breathing would be one sign.
