Mouth breathing can dry out your mouth, and saliva plays a big role in protecting teeth. When saliva levels drop, bacteria and acids have an easier time sticking around.
Over time, this can lead to irritated gums, bad breath, and a higher risk for cavities since teeth are not getting their natural defense.
