• People suffering from chronic sinus problems are more likely to breathe through their mouths. 
• Mouth breathing can lead to oral health issues and sleep disorders. 
• Some signs that you are a mouth breather include sleeping with your mouth open, snoring, drooling while sleeping, and irritability during the day.

Mouth breathing, the habit of breathing through your mouth rather than your nose, is an unpleasant side effect of sinus problems and can cause several health issues. According to Dr. Monty Trimble of Dallas Breathe Free, breathing properly is very important.

“Other than speaking or eating in general we're supposed to breathe through our nose because the nose is a filtering mechanism and also warms the air,” Dr. Trimble told the NE Dallas News. “The mouth is really not made for that purpose, the saliva in the mouth is very good at preventing infection and helping to heal things in the mouth, but when we begin to open our mouth when we breathe in a dysfunctional way the mouth dries out so it's harder for things to heal and then as a mouth dries out, it can be more irritating and people can develop oral health conditions. That's why I think for all health it's very important to breathe normally through the nose that way at night, our mouth is closed and not open.”

People who suffer from allergies or chronic sinus problems are more likely to breathe through their mouths, but mouth breathing can lead to oral health issues, according to McCarl Dental Group. Mouth breathing dries up saliva, allowing bacteria and plaque to build up on the teeth, which can cause cavities, gum disease, and chronic bad breath. Over time, regularly breathing through the mouth can also lead to strained jaw joints, snoring, sleep apnea, enlarged tonsils, and a higher risk for airway disorders, such as asthma. 

KTM Yoga reports that although most people should breathe through their noses most of the time, as much as 60% of adults often breathe through their mouths. Hair and mucus within the nose act as filters that trap bacteria and dust. Nasal breathing also increases oxygen intake and boosts brain activity. Another benefit of breathing through the nose is that it helps to slow airflow, which widens blood vessels and slows the heart rate, leading to a feeling of calm.

According to Healthline, mouth breathing dries out the mouth, creating the proper environment for gingivitis and cavity development. Overall, nose breathing is more beneficial than mouth breathing.

Chronic sinus problems are one reason that people may begin snoring, according to Kaplan Sinus Relief. Short-term effects of snoring include fatigue during the day, headaches, chest pain during the night, and a sore throat in the morning. Snoring takes place when your body is unable to breathe properly through the nose while sleeping, which can happen when the sinuses are inflamed or infected. Breathing through the mouth while sleeping causes the airways to narrow, and the soft tissues in the throat vibrate, causing the snoring sound.

According to Dallas Breathe Free's website, Dr. Monty Trimble is certified in otolaryngology. He earned his bachelor's degree in biochemistry from Texas A&M University and completed his medical education at the University of Texas Health Science Center in San Antonio. Dr. Trimble then completed his residency in otolaryngology at the University of Missouri Hospital and Clinics.
