Children produce clicking noises for a wide range of reasons, from completely harmless habits to conditions that benefit from professional attention. The sound can originate in the ears, the jaw joint, the soft palate, the throat, or even the child’s own deliberate behavior. Pinpointing the source usually comes down to when the clicking happens, where in the body it seems to come from, and whether the child can control it.
Ear Clicking and the Eustachian Tube
One of the most common sources of clicking in children is the Eustachian tube, the narrow passage that connects the middle ear to the back of the throat. Every time you swallow, yawn, or move your jaw, the tube briefly opens to equalize pressure on both sides of the eardrum. That opening can produce a soft click or pop. Research into these “physiological” ear clicks has found that the sound appears at the moment the tube opens and is likely caused by a thin film of mucus on the tube’s lining being briefly disrupted, much like a soap bubble popping on a tiny scale.1PubMed. Physiological Ear Clicking: Its Origin and Potential Usability as a Test Tool for the Eustachian Tube Function
Most children never notice this sound, but some become aware of it and start asking about it or trying to reproduce it on purpose. If your child says they hear clicking “inside their head” or near their ears during swallowing, there is a good chance the Eustachian tube is the culprit. The sound is typically harmless. It becomes worth investigating only if it accompanies ear pain, a sense of persistent fullness, or hearing loss, which could suggest Eustachian tube dysfunction or fluid behind the eardrum.
Jaw Joint Sounds
The temporomandibular joint, or TMJ, sits just in front of each ear and connects the lower jaw to the skull. A small disc of cartilage cushions the joint, and when that disc shifts out of its normal position, it can produce a noticeable click or pop every time the child opens or closes their mouth. This kind of disc displacement is the most common form of TMJ disorder and often shows up as clicking, jaw pain, limited mouth opening, or an uneven chewing pattern.2Journal of Clinical Pediatric Dentistry. Updates in orthodontic treatment of temporomandibular joint disc displacement in adolescents: review of the literature
In younger children, jaw clicking can also arise from bite misalignment. A case study of a child under four with a crossbite on one side found that the affected-side jaw joint moved before the opposite joint during mouth opening, creating asymmetric motion. After the crossbite was corrected, the two sides coordinated much better and chewing became more balanced.3Cranio. Improvement in jaw motion following treatment of unilateral crossbite in a child with primary dentition: a case report The takeaway for parents is that clicking linked to chewing or wide mouth opening often traces to the jaw joint, and dental evaluation can clarify whether anything structural is going on.
Occasional, painless jaw clicking in a child who eats and speaks normally is not usually a cause for concern. But if clicking is accompanied by pain, difficulty opening the mouth fully, or a jaw that seems to lock in place, a pediatric dentist or orthodontist should take a look.
Tics and Repetitive Vocal Clicking
Some children make clicking sounds as a tic, a brief, repetitive, semi-involuntary movement or sound. Tics are remarkably common in childhood. Transient, mild tics show up in as many as roughly one in seven elementary-school-age children, while a more persistent combined motor and vocal tic disorder, Tourette syndrome, affects about one in a hundred children with widely varying severity.4PubMed Central. Tourette Syndrome and Other Tic Disorders in Childhood, Adolescence and Adulthood Clicking, throat-clearing, sniffing, and tongue-clucking are all well-documented vocal tics.
The hallmark of a tic-related clicking sound is that it comes and goes, often waxes and wanes over weeks or months, tends to increase during stress or excitement, and may shift to a different sound or movement over time. Many children feel a brief urge or tension before the tic that is temporarily relieved by performing it. Parents frequently notice that the clicking disappears when the child is deeply focused on something enjoyable and returns when they are bored or anxious.
Most childhood tics fade on their own by adolescence without any treatment. When tics are frequent enough to bother a child socially or interfere with school, behavioral approaches like habit reversal training are a first-line option. A recent study found that combining music therapy with habit reversal training over eight weeks significantly reduced tic severity scores compared to habit reversal alone, with an overall effectiveness rate above 90 percent in the combined group.5PubMed Central. Effects of Music Therapy Combined with Habit Reversal Training on Children with Tic Disorders: A Retrospective Study The good news is that medication is rarely needed for mild-to-moderate tics, and many children outgrow them entirely.
Soft Palate Clicking (Palatal Myoclonus)
Less commonly, a clicking sound comes from rapid, rhythmic contractions of the muscles in the soft palate, the fleshy tissue at the back of the roof of the mouth. This is called palatal myoclonus or palatal tremor, and it produces clicks that can be audible not just to the child but to anyone standing nearby. In a reported case, a five-year-old boy experienced clicking in both ears that was audible to an examiner within about ten centimeters. A physical exam revealed rhythmic bilateral movements of the soft palate producing the sound.6PubMed. Objective tinnitus due to essential palatal tremor in a 5-year-old
There are two forms of this condition. In the “essential” type, which is more relevant to otherwise healthy children, the clicking is associated with an internal clicking sensation or tinnitus. The child can sometimes start and stop the movements voluntarily, the clicking ceases during sleep, and it is not lifelong.7PubMed Central. Loud clicking sounds associated with rapid soft palate muscle contractions The other type, “symptomatic” palatal myoclonus, involves an identifiable brain lesion and is far rarer in children.
If you can see the back of your child’s throat twitching in rhythm with the clicks, that is a strong clue. A pediatric neurologist can confirm the diagnosis, but in many pediatric cases the essential form resolves over time and does not require aggressive treatment.
Throat and Neck Clicking During Swallowing
Some children produce a click in the front of the neck that coincides with swallowing or turning the head. This so-called “clicking larynx” or “clicking throat” involves structures in the voice box and the small horseshoe-shaped bone above it, the hyoid. Patients with this presentation typically notice a clicking sensation in the neck during head movement or swallowing.8PubMed Central. A Throat that Clicks
The underlying cause is usually anatomical. The clicking can result from an unusually elongated or thickened hyoid bone contacting the cervical spine during swallowing, the thyroid cartilage bumping against the hyoid, or ossification of the tissue connecting those two structures.9Practica Oto-Rhino-Laryngologica. A case of clicking of the larynx and hyoid bone while swallowing In a growing child, these variants can become more or less noticeable as the skeleton matures. The condition is generally painless and benign, though in rare cases where the clicking is accompanied by discomfort or difficulty swallowing, surgical trimming of the offending bone has been performed.
Airway-Related Sounds in Infants and Toddlers
In babies and very young children, clicking or similar noisy breathing can come from the airway itself. Laryngomalacia, a condition in which the tissues above the vocal cords are floppy and partially collapse inward during breathing, is the most common cause of noisy breathing in infants. While the signature sound is usually a high-pitched inspiratory stridor, some infants produce clicking or popping sounds as well, particularly during crying or feeding. Acoustic analysis of an infant with laryngomalacia found that the crying episode was longer than normal and contained proportionately more inspiratory sounds and more irregular sound qualities compared to typical infants.10Logopedics Phoniatrics Vocology. Acoustic characteristics of crying in infantile laryngomalacia
Enlarged adenoids are another airway factor. Children with adenoid hypertrophy often develop a nasal or “blocked” quality to their speech, and the changes in airflow can produce unusual oral sounds. A study comparing children with adenoid enlargement to controls found significantly higher rates of sound substitution and nasalization in the adenoid group.11PubMed Central. Articulation error of children with adenoid hypertrophy While this does not always manifest as a discrete “click,” the altered resonance and compensatory mouth movements can lead parents to describe unfamiliar sounds that fall into the clicking or clucking category.
If your baby makes clicking sounds specifically during breastfeeding, the most likely explanation is a latch issue. The baby may be breaking suction repeatedly on the breast, producing an audible click with each break. A tongue tie can contribute to this pattern, though many clicking babies simply need a positional adjustment. A lactation consultant can usually sort this out in one visit.
Oral Habits and Their Ripple Effects
Prolonged thumb sucking, pacifier use, or habitual tongue thrusting can change the shape of a child’s palate and the alignment of their teeth over time. These structural shifts can in turn alter how the tongue, lips, and jaw interact during speech and swallowing, sometimes producing unusual sounds. Oral habits have been shown to interfere with normal jaw growth, contribute to open bite, and change swallowing and speech patterns depending on how long, how often, and how forcefully the habit occurs.12PubMed Central. Breaking the Thumb Sucking Habit: When Compliance Is Essential
A child who has developed an anterior open bite from a sucking habit may compensate by pressing the tongue forward or sideways during speech, which can generate clicking or clucking sounds that were not present before the bite changed. Addressing the habit early is important because the open bite associated with these habits can often be corrected with simple interceptive measures, but only if the habit itself stops first. Otherwise, the malocclusion tends to recur.
Medication-Related Oral Movements
Although rare in young children, certain medications can cause involuntary repetitive movements of the mouth and face known as orofacial dyskinesias. These movements can include lip smacking, tongue protrusion, chewing motions, and clicking sounds. The phenomenon is most commonly associated with long-term use of antipsychotic medications.13PubMed Central. Orofacial dyskinesia. Clinical features, mechanisms and drug therapy While this mainly affects older adults in psychiatric care, children who take certain psychotropic medications for behavioral conditions can occasionally develop similar movements. If your child is on any such medication and starts making new mouth or clicking sounds, it is worth flagging to the prescribing doctor promptly, because early recognition can prevent the movements from becoming entrenched.
Deliberate Clicking and Self-Taught Echolocation
Sometimes the clicking is entirely voluntary and purposeful. Some children, especially those who are blind or have significant visual impairment, discover on their own that making sharp tongue clicks and listening to how the sound bounces off walls and objects helps them navigate their surroundings. This is human echolocation, the same principle used by bats and dolphins, adapted through palate clicks. A training study found that both blind and sighted participants of various ages improved substantially in echolocation tasks over a ten-week period. Participants who were blind reported improved mobility, and more than four in five reported better independence and wellbeing after learning the skill.14PLoS One. Human click-based echolocation: Effects of blindness and age, and real-life implications in a 10-week training program
Even some sighted children experiment with clicking as a form of play or sensory exploration, testing how sounds change in hallways, stairwells, and open rooms. This kind of clicking is voluntary, situation-dependent, and not a sign of any disorder. If a blind child has developed the habit, it is worth encouraging rather than discouraging, since formal echolocation training has demonstrated real benefits for daily life.
When to Seek Professional Evaluation
Not every clicking sound warrants a trip to the doctor. If the sound is occasional, painless, and does not bother the child, watchful waiting is a reasonable approach, particularly because many childhood tics and Eustachian tube clicks resolve without intervention. A few situations, however, tip the balance toward getting an evaluation:
- Jaw locking or pain: Clicking that comes with difficulty opening the mouth, pain while chewing, or a jaw that gets stuck points toward a TMJ issue that a pediatric dentist should assess.
- Audible clicking others can hear from a distance: When the clicks are loud enough for people across the room to notice, palatal myoclonus or a related neuromuscular condition is worth ruling out.
- Clicking during feeding in infants: Persistent clicking at the breast or bottle may indicate a latch problem or tongue tie, and a lactation consultant or pediatrician can evaluate.
- Worsening tics or social distress: If clicking tics increase in frequency, begin interfering with school, or cause the child significant embarrassment, a pediatric neurologist can discuss behavioral interventions.
- New involuntary movements on medication: Any new repetitive mouth or face movements in a child taking psychotropic medication should be reported to the prescribing physician quickly.
- Noisy breathing or swallowing difficulty: Clicking accompanied by stridor, choking episodes, or trouble swallowing suggests an airway or structural issue that needs a direct look by an ENT specialist.
For most children, the clicking turns out to be one of those quirky, benign things developing bodies do. Keeping a brief log of when the clicking happens, whether the child can control it, and any accompanying symptoms gives any clinician a head start if you do decide to have it checked.
