MOUTH BREATHING dries out your saliva, and saliva is your teeth’s #1 defense against cavities 🦷
Less saliva = more acid, more bacteria, more decay. Fix the breathing, save your teeth.
🦷 👅Here’s how:
Mouth breathing causes cavities mainly by drying out your mouth. Saliva is your teeth’s main defense: it washes away food and bacteria, neutralizes acid, and delivers calcium and phosphate that repair early enamel damage. Air flowing over your tongue and teeth, especially during sleep, evaporates that saliva.
What happens next:
• Lower pH: Without saliva buffering, plaque bacteria’s acid stays in contact with enamel longer, so teeth demineralize faster than they repair.
• Bacterial shift: A dry mouth favors acid-producing, acid-tolerant bacteria like Streptococcus mutans and lactobacilli.
• Less rinsing: Sugars and food debris linger instead of being cleared.
• Gum and soft-tissue changes: Dryness often brings gum inflammation and bad breath too, and root surfaces exposed by recession are especially cavity-prone.
If you or your child is chronically mouth breathing, there may be a tongue tie, tongue muscle tone, or jaw development /nasal passage issue.
Seeing a myofunctional therapist or airway focused dentist should be a first stop in finding out more!
