Many people breathe through their mouths without giving it a second thought. It may happen during sleep or when allergies strike. But over time, this seemingly small habit can lead to big changes in your dental health.
Why Do People Breathe Through Their Mouths?
Mouth breathing can stem from a variety of causes. For some, it’s seasonal allergies or a common cold. For others, structural challenges – like a deviated septum – make nasal breathing more difficult. Some people may also breathe through their mouths out of habit, especially during sleep.
As Dr Yvonne Monte (Dentist) explains, “Breathing through the nose is our body’s natural filter. When that filter is bypassed, the mouth is left vulnerable, dry, exposed, and out of balance. That’s when dental concerns begin to appear.”
How It Affects the Health of Your Mouth
When the mouth becomes the primary airway, several things can shift:
- Dry mouth sets in. Saliva acts as your mouth’s natural defence system – rinsing away food particles, neutralising acids, and maintaining the balance of bacteria. Without enough saliva, the risk of tooth decay and gum disease increases.
- Bad breath becomes more likely. In a dry mouth, bacteria flourish, often causing halitosis.
- Facial and dental development may be affected. In children, mouth breathing can influence the growth of facial structures and lead to misaligned teeth that may later require orthodontic treatment.
- Gum health suffers. Dry, bacteria-rich environments can accelerate inflammation and the early stages of gum disease, including gingivitis.
- The oral microbiome is altered. Mouth breathing can disrupt the natural balance of bacteria in the mouth, encouraging harmful strains to grow while reducing beneficial ones. This shift can increase the likelihood of tooth decay, infections, and chronic inflammation.
What Can You Do?
If you or your child has noticed signs of mouth breathing – such as dry lips, open-mouth sleeping, or frequent congestion – it’s worth seeking professional support. A dentist, GP, or ENT specialist can help identify the root cause and recommend proper treatment.
A Healthier Habit, A Healthier Smile
While mouth breathing may seem like a minor detail, its effects on your dental health can be far-reaching. With awareness and early action, you can restore balance, protect your smile, and support overall wellness.
