Mouth breathing may seem like a harmless habit — after all, you’re getting the air you need, right? — but in reality, it can significantly impact your oral health and overall wellbeing. It’s a common issue among children and adults alike, and many people don’t even realize they’re doing it, much less the far-reaching effects it can have on health.
At VIP Smiles, we know that oral health goes beyond the mouth. Achieving a healthy, happy smile often requires a full-body approach, which includes the way you breathe. If you suspect you or your child are a mouth breather, keep reading to learn more about how this habit can negatively affect your oral health and what to do about it.
Nasal Breathing vs. Mouth Breathing
As humans, we can breathe through both our noses and mouths. Nose breathing filters, warms, and humidifies the air before it reaches your lungs, helping you breathe easier. However, if you need to breathe through your mouth every once in a while due to nasal congestion, that’s fine — the problem comes when you do it all the time.
Chronic mouth breathing can occur due to a deviated septum or structural airway issues, enlarged tonsils and/or adenoids, sleep apnea, or medications that cause nasal dryness or congestion. Some people simply breathe through their mouth because it has become a habit over time. But no matter the cause, it can have destructive effects on your oral health.
How Mouth Breathing Affects Oral Health
Let’s take a closer look at the specific effects of mouth breathing on oral health:
Dry Mouth (Xerostomia)
One of the biggest issues with mouth breathing is that it causes a dry mouth. Saliva neutralizes acids, washes away bacteria, and strengthens the enamel. Without a moist, balanced oral environment, you’re at a greater risk of bacteria growth, making you more likely to develop cavities, tooth sensitivity, or enamel erosion.
Tooth Decay and Gum Disease
The dry conditions caused by mouth breathing allow acid-producing bacteria to thrive, increasing plaque buildup and enhancing your risk of cavities. Additionally, dry tissue is more prone to irritation and infection, making you more likely to experience bleeding gums, gingivitis, periodontal disease, oral thrush, and sores.
Bad Breath (Halitosis)
When mouth breathing dries out the oral environment, your mouth becomes a breeding ground for bad breath-causing bacteria. If you breathe through your mouth at night, your morning breath is likely worse.
Changes in Bite and Facial Development
Chronic mouth breathing can affect children’s jaw growth and tooth alignment, putting them at a higher risk of developing a narrow palate, crowding, and orthodontic issues. It can also impact facial structure and airway development.
Signs You or Your Child May Be a Mouth Breather
If you’re in the habit of mouth breathing, chances are, you’re so used to it that you don’t even notice when you’re doing it, especially at night. Be on the lookout for these signs that you or your child may be a mouth breather:
- Frequently waking up with dry mouth or sore throat
- Chronic bad breath despite good dental hygiene
- Snoring or restless sleep
- An open-mouth posture during the day
- Chapped lips and frequent thirst
- Nasal congestion that never fully goes away
- Frequent cavities, speech issues, or orthodontic crowding in children
Treatment and Prevention Options
Protecting Oral Health
If you suspect an issue with mouth breathing, let your dentist know. They can look for dry tissues, gum inflammation, enamel wear, and cavity patterns that can indicate mouth breathing. In children, they can identify orthodontic crowding and development issues that often result from improper breathing habits.
Your dentist can help manage the effects of mouth breathing by providing fluoride treatments, filling cavities, prescribing dry mouth products or saliva substitutes, advising you on proper hydration habits, and recommending sugar-free gum or lozenges to stimulate saliva production.
Treating the Underlying Cause
It’s also important to address the underlying cause of mouth breathing. If necessary, your dentist can collaborate with physicians, ENT specialists, or sleep specialists to identify and treat the root cause of your breathing issues and prevent oral health issues from worsening.
Behavioral and Habit Changes
Changing your behavior and habits can also make a big difference. Your dentist or doctor may recommend proper sleep positioning, breathing awareness techniques, or humidifier use to help you breathe easier through your nose.
