Parents Ask Why Their Child Snores. A Dentist Sees Part of the Answer

A snore is the sound of tissue vibrating as air squeezes through a narrow airway. A cold or allergy explains some noisy nights. Enlarged tonsils and adenoids are the most common cause of childhood sleep apnoea. Jaw width, tongue posture and palate shape play a part for some children. At JuniorDental, every standard exam includes an airway evaluation. Your paediatrician covers the medical side.

Maybe you stopped outside your child’s bedroom door last night and listened. Maybe a grandparent mentioned the noise first. Either way, you noticed, and noticing is a fair place to start.

Did you know our standard exam looks at jaw width, tongue posture and palate shape? Each one gives a clue about the space air has to move through.

Why does my child snore at night?

TL;DR: A snore has several causes, and tonsils, adenoids and nasal congestion head the list.

Childhood snoring is common. The NHS website Healthier Together says about one child in ten snores. The Royal Children’s Hospital Melbourne says 15% to 20%.

Most children who snore do not have sleep apnoea. The American Academy of Pediatric Dentistry (AAPD) puts the rate at roughly 1% to 4%.

A cold or seasonal allergy may cause sudden snoring. In most cases it clears up, says Texas Children’s Hospital.

Enlarged tonsils and adenoids behave differently. The University of Miami Health System says snoring from them usually continues without treatment. The Royal Children’s Hospital Melbourne says they grow fastest between ages two and seven.

Airway shape matters too. The same hospital lists very small jaws or flat faces as other causes of apnoea. Jaw and facial structure is the part of the picture a dentist sees.

Which other signs matter alongside snoring?

TL;DR: Three or more snoring nights a week, plus other signs, deserve a paediatrician’s time.

The American Academy of Pediatrics (AAP) lists frequent snoring as a sign to follow up. It counts three or more nights a week as frequent.

Night-time signs on the AAP and AAPD lists include laboured breathing and gasping or snorting. Others are breathing pauses a parent notices, restless sleep and frequent waking.

The AAP also lists sleeping upright or with the neck arched back. A return to bedwetting after six or more months of dry nights makes the list.

Daytime signs on the lists include morning headaches, sleepiness, attention problems and learning difficulties. The AAP links sleep apnoea with problems in thinking, learning and behaviour.

Regular snoring plus any other sign on the list changes the picture. The AAP then advises doctors to arrange a sleep study or refer to a specialist. A sign is a reason to ask a question. It is not a diagnosis.

How do jaw width and tongue posture affect breathing?

TL;DR: Narrow jaws restrict airway space, and a low tongue means less widening force.

The upper jaw forms the roof of the mouth and the floor of the nose. A narrow upper jaw restricts airway space.

The AAP lists a high-arched palate among the findings to note in a snoring child. It also lists a small or set-back lower jaw.

A low-resting tongue gives the upper jaw less natural widening force. Long-term mouth breathing goes with longer, narrower facial growth patterns.

A 2010 study compared 55 mouth-breathing children with 61 nasal breathers. All were orthodontic patients. The mouth breathers had narrower upper and lower arches and a taller lower face.

Posterior crossbite appeared in 49% of mouth breathers and 26% of nasal breathers. In a crossbite, the upper back teeth bite inside the lower ones. A narrow upper jaw may be the reason.

The study looked back at records, so it shows a pattern, not proof of cause.

A 2022 Dubai study used a sleep questionnaire with 65 children aged 7 to 16. All were healthy children seeking paediatric dental care. The questionnaire flagged 12.3% as high risk for sleep-disordered breathing.

Larger tonsils had the strongest statistical link. Higher body mass index, posterior crossbite and a Class II molar relationship also showed links. Class II describes a lower jaw sitting behind the upper.

The convenience sample was small, so the figures offer a hint, not a Dubai-wide rate.

What does an airway evaluation at JuniorDental look for?

TL;DR: Every standard exam at JuniorDental includes an airway evaluation, from birth onward.

We look at four things: jaw width, tongue posture, palate shape and breathing patterns. Poor airway development affects sleep quality and cognitive performance, so we look early.

Assessments start from birth. The AAPD recommends a check-up every six months. Repeat visits give us more than one look as your child grows.

An airway evaluation looks at structure. It does not measure sleep, and it does not diagnose sleep apnoea. When we notice a pattern, we tell you what we see.

You hear the nights. We see the mouth. Tell us what you hear, how many nights a week and for how long.

Who else looks at a snoring child?

TL;DR: Your paediatrician leads, and a dentist adds the view of jaw, palate and tongue.

In our view, regular snoring belongs with your paediatrician first. The AAP asks doctors to inquire about snoring at routine health visits. The AAPD advises dentists to refer suspected sleep apnoea to a medical provider.

When sleep apnoea comes with enlarged tonsils and adenoids, the AAP names adenotonsillectomy first-line. Adenotonsillectomy means surgery to remove the tonsils and adenoids.

Dental treatment has a narrower role. The AAPD says rapid maxillary expansion rests on small studies without control groups. Follow-up periods are relatively short.

The AAP says expansion may be effective in specially selected patients. The AAPD advises appliances only after a complete orthodontic and craniofacial assessment.

Healthier Together says sleep videos help, so a short clip is worth recording. The AAP advises calling emergency services if breathing stops for more than 20 seconds. The same goes for pale, blue or grey skin.

Frequently Asked Questions

Is snoring normal in children?

Childhood snoring is common, and most children who snore do not have sleep apnoea. A cold or seasonal allergy may cause noisy nights, which usually clear up. Regular snoring is different, so mention it to your paediatrician. A short sleep video helps the conversation.

What is the difference between occasional and regular snoring?

Occasional snoring comes and goes, such as during a cold or seasonal allergy. Texas Children’s Hospital says sudden snoring from either clears up in most cases. The American Academy of Pediatrics counts three or more snoring nights a week as frequent. Frequent snoring, especially with other signs, is the point to raise with your paediatrician.

Does a narrow jaw affect breathing?

Narrow jaws restrict airway space, so jaw width matters for some children. Tonsils, adenoids and nasal congestion matter as well, and your paediatrician checks them. A 2010 study of 116 orthodontic patients found narrower arches in mouth breathers. Such studies show a pattern, not proof of cause.

At what age does JuniorDental assess airway health?

From birth. Every standard exam at JuniorDental includes an airway evaluation. It covers jaw width, tongue posture, palate shape and breathing patterns. We see children from birth to early adulthood. The American Academy of Pediatric Dentistry recommends a check-up every six months.

What happens if the exam finds an airway cause?

It depends on the cause. Enlarged tonsils or adenoids belong with your paediatrician or an ear, nose and throat doctor. For a narrow upper jaw, expansion between ages 6 and 12 widens the arch. Expansion also opens nasal airway space. JuniorDental offers fixed and removable palatal expanders, plus Invisalign First. A full assessment comes first.

Does a dental exam diagnose sleep apnoea?

No. A doctor makes the diagnosis. The American Academy of Pediatrics recommends a sleep study when snoring comes with other signs. A dental exam adds information about the jaw, palate and tongue. We tell you what we see, and your paediatrician weighs it.

Who checks child snoring in Dubai?

Start with your paediatrician or GP, who leads the medical assessment. Ear, nose and throat doctors and sleep specialists handle tonsils, adenoids and sleep studies. JuniorDental adds a dental airway evaluation at either of our two Dubai clinics. Tell us about the snoring when you book.

How do you raise snoring at your child’s next visit?

Tell us what you hear at night, and we will look with it in mind.

The information above is general and does not replace a doctor’s examination. If your child snores, book a visit with JuniorDental, a paediatric dentist in Dubai. We care for children from birth to early adulthood at two Dubai clinics. Come with your questions and a short sleep video. Nobody expects you to know the cause, and nobody judges a noisy night.
