Newborns Sleeping With Mouth Open: What Parents Should Know

why does my newborn sleep with her mouth open

It is not uncommon for newborns to sleep with their mouths open, and while it may look cute, it could be a sign of a medical issue. Newborns breathe almost exclusively through their noses, so mouth breathing could indicate a blockage in the upper airway, such as a stuffy nose from a cold or allergies. If it persists, mouth breathing can lead to complications, including dental issues, sleep apnea, and long face syndrome, where the lower facial features elongate disproportionately. If your newborn sleeps with their mouth open, it is important to observe and consult a healthcare professional if concerned.

Mouth breathing may indicate a blocked nasal passage

Mouth breathing in newborns is usually due to a blockage in the nasal passage. This could be caused by a deviated septum, which is when the cartilage and bone in the nose are collapsed, deformed, or bent, blocking one nostril. A deviated septum can be congenital or caused by an injury during childbirth.

Newborns can also experience nasal congestion due to allergies or a cold, which can make breathing through the nose difficult. Allergies can cause an increase in mucus production, leading to a blocked nose and forcing the baby to breathe through their mouth. Even in the absence of a runny nose or stuffed-up sound, a blockage can occur due to the tiny size of newborn nostrils.

In some cases, mouth breathing in newborns can be a symptom of sleep apnea, which is caused by an obstruction in the upper airway, such as enlarged tonsils or adenoids. This can lead to snoring, pauses in breathing, restlessness, and coughing or choking. Sleep apnea is a rare condition in newborns but can be fatal in some cases, so it is important to consult a pediatrician if you notice any of these symptoms.

Babies may develop allergies early on, causing a blocked airway

Newborns typically breathe through their noses, almost exclusively. So, if your newborn sleeps with their mouth open, it could be a sign of a blocked nose or nasal passage. This could be due to a stuffy nose, a cold, or allergies. Babies can't easily clear mucus on their own, so they may compensate by breathing through their mouths. Mouth breathing in newborns could also be due to problems with their bite and mouth structure, such as an inability to close their mouths properly because of the shape of their jaw.

If you notice that your newborn is sleeping with their mouth open, it is important to monitor for any other symptoms that may accompany it. Some possible symptoms to look out for include snoring, restlessness during sleep, pauses in breathing, coughing, choking, irritability, cracked lips, and excessive crying. These symptoms could indicate underlying issues such as sleep apnea, enlarged tonsils or adenoids, or other physical obstructions in the upper airway.

If you suspect that your newborn's mouth breathing is due to allergies or any other respiratory issues, it is important to consult a pediatrician or a healthcare professional. They can advise you on the necessary testing, such as an overnight sleep study, and recommend appropriate treatment options. Treatment for allergies may include medications, such as Flonase or Rhinocort, to help manage the symptoms and improve your baby's breathing.

It is worth noting that mouth breathing during sleep can sometimes become a habit, even after the underlying issue has resolved. This can lead to potential dental health concerns and other overall health issues, including behavioural problems such as irritability and a lack of focus. Therefore, addressing the cause of mouth breathing early on is crucial to prevent any long-term complications.

Mouth breathing can lead to dental and health issues

Mouth breathing can lead to various dental and health issues. Firstly, it can cause dental issues such as tooth decay and gum disease. This is due to the decrease in saliva production that results from mouth breathing, leading to a dry mouth environment that is conducive to the growth of harmful bacteria and an increase in cavities. The constant airflow can also dry out and inflame the gums, causing redness, swelling, and an increased risk of gingivitis.

Mouth breathing can also lead to skeletal abnormalities and changes in facial structure, such as a longer, narrower face and jaw, often referred to as "mouth breather jaw" or "adenoid face". These alterations can affect the alignment of teeth, leading to dental malocclusions or misalignments of the teeth and jaw, further complicating oral hygiene efforts and overall well-being.

In addition to the physical changes, mouth breathing can cause behavioural problems in children, including symptoms similar to those found in children with attention deficit hyperactivity disorder (ADHD). It can also contribute to an inability to focus, irritability, and lack of sleep.

Mouth breathing can be a result of an obstruction in the nasal passage, such as a blocked nose or throat, or it can be due to problems with the bite and mouth structure, such as the shape of the jaw preventing the mouth from closing properly.

If you are concerned about your newborn's sleeping habits, it is important to consult a healthcare professional for personalized advice and guidance.

While mouth breathing may be harmless in some cases, it can also be a sign of breathing difficulties or other health issues. If you are concerned, it is always best to consult your paediatrician or a healthcare professional.

Mouth breathing can lead to various health and dental issues over time. It can cause a decrease in saliva production, leading to bad breath, tooth decay, and other dental problems. Additionally, mouth breathing can affect a child's speech development, causing them to struggle with certain sounds or develop a lisp. In some cases, mouth breathing can also contribute to behavioural problems, including irritability, lack of focus, and lack of sleep.

If your baby seems to be struggling to breathe or exhibits other symptoms such as snoring, restlessness during sleep, or pauses in breathing, it is important to seek medical advice.

  • Loud snoring
  • Pauses in breathing during sleep
  • Restless sleep
  • Daytime sleepiness

These symptoms can indicate a more serious condition, so it is always best to seek medical advice if you are concerned. In some cases, mouth breathing in newborns can be caused by enlarged adenoids or tonsils, a deviated septum, or allergies, all of which can contribute to sleep apnea.

If your newborn is breathing through their mouth while sleeping, it is important to address the issue promptly. Mouth breathing can lead to long-term health consequences if left untreated. It is always recommended to consult a pediatric dentist or a doctor to help resolve the issue and ensure your baby's overall health and wellbeing.
