Did you know waking up with a dry mouth could be connected to the way you breathe while you sleep?
Nighttime mouth breathing can happen for several reasons, including nasal congestion, allergies, a deviated septum, enlarged tonsils, certain medications, or sleep-related breathing problems.
When you breathe through your mouth for hours at a time, your mouth loses moisture, and saliva cannot protect your teeth as effectively.
Saliva helps neutralize acids, wash away food particles, and protect tooth enamel. Without enough of it, you may be more likely to experience cavities, bad breath, gum irritation, or increased tooth sensitivity.
Your dentist can often spot signs of chronic dry mouth during a routine dental exam. They can evaluate how it is affecting your teeth and gums, recommend ways to protect your mouth, and help determine whether you should speak with your physician, ENT, or sleep specialist about the underlying cause.
If you regularly wake up with a dry mouth, sore throat, persistent bad breath, or feel like you sleep with your mouth open, bring it up at your next appointment.
