Teething can indirectly cause watery eyes due to irritation and increased tear production linked to inflammation and discomfort.
Understanding the Connection Between Teething and Watery Eyes
Teething is a natural developmental stage that infants go through, typically beginning around 4 to 7 months of age. It involves the eruption of primary teeth through the gums, which can cause significant discomfort. Parents often notice a variety of symptoms during this period, including drooling, irritability, gum swelling, and sometimes even a slight fever. Among these symptoms, watery eyes may also be observed. But is there a direct link between teething and watery eyes?
The short answer is yes—teething can cause watery eyes, but not because the teeth themselves affect the eyes directly. Instead, the process of teething triggers physiological responses that may lead to increased tear production or eye irritation.
The underlying mechanism involves the close proximity of nerves and tissues in an infant’s face. The inflammation and discomfort in the gums can stimulate nearby nerve pathways that also influence tear glands. This can result in watery or teary eyes as a side effect of the overall irritation caused by teething.
Why Does Teething Cause Symptoms Beyond Gum Pain?
Teething is more than just teeth pushing through gums; it’s an inflammatory process that activates the body’s immune response. The gum tissues become swollen and tender as new teeth break through, which releases inflammatory mediators such as prostaglandins and cytokines. These substances trigger localized swelling but also affect neighboring areas.
Babies have highly sensitive facial nerves like the trigeminal nerve, which transmits sensory information from the face to the brain. This nerve has branches near both the gums and around the eyes. When inflammation occurs in one area (the gums), it can stimulate nerve endings linked to other regions (the eyes), causing reflex tearing or watery eyes.
Moreover, excessive drooling combined with rubbing or wiping near the eyes can irritate delicate skin around them. This mechanical irritation adds to tear gland stimulation or mild conjunctival irritation, increasing wateriness.
Common Teething Symptoms That May Accompany Watery Eyes
- Gum swelling and redness
- Increased saliva production (drooling)
- Fussiness or irritability
- Slight rise in body temperature
- Chewing or biting on objects
- Rubbing face or eyes frequently
- Mild nasal congestion
While watery eyes are not among classic teething symptoms like drooling or gum soreness, they often appear alongside these signs due to shared nerve pathways and physical irritation.
The Physiology Behind Watery Eyes During Teething
Tears serve several purposes: lubricating the eye surface, protecting against infection, and flushing out irritants. Tear production is controlled by lacrimal glands located above each eye and regulated by neural inputs from cranial nerves.
When an infant experiences gum inflammation during teething, sensory nerves send signals that sometimes cross over to stimulate lacrimal glands inadvertently. This neural cross-talk leads to reflex tearing even though no direct eye injury exists.
Additionally, swollen gums can cause mild discomfort that makes babies rub their faces more vigorously. This action may introduce foreign particles or saliva into the eye area causing mild conjunctivitis-like symptoms—redness with tearing.
How Nerve Pathways Influence Tear Production
The trigeminal nerve (cranial nerve V) plays a huge role here. It has three main branches:
| Branch | Area Served | Relation to Teething & Eyes |
|---|---|---|
| Ophthalmic (V1) | Forehead & Eye Region | Stimulates lacrimal gland for tears; affected by facial irritation |
| Maxillary (V2) | Upper Jaw & Cheeks | Sensory input from upper gums; inflammation here triggers signals |
| Mandibular (V3) | Lower Jaw & Chin | Sensory input from lower gums; involved in chewing reflexes |
Inflammation in maxillary or mandibular regions during teething sends signals that may indirectly activate ophthalmic branches causing increased tear secretion.
Differentiating Watery Eyes Caused by Teething From Other Conditions
Watery eyes alone don’t necessarily mean teething is responsible. Several other conditions can cause excessive tearing in infants:
- Conjunctivitis: Infection or allergy causing redness and discharge.
- Nasal Congestion: Blocked nasal passages increase tear overflow.
- Lacrimal Duct Obstruction: Tear drainage blockage common in newborns.
- Irritants: Dust, smoke, or foreign bodies causing eye watering.
- Crying: Emotional tears due to distress unrelated to teething.
To conclude if teething is behind watery eyes:
- Check for other teething signs like gum swelling and drooling.
- Observe if symptoms worsen when baby chews on toys.
- Look for absence of redness or thick discharge typical of infections.
- Note if watery eyes improve as teeth fully emerge.
If watery eyes come with fever above 101°F, persistent redness, pus discharge from eyes, or prolonged fussiness unrelated to feeding/teething relief methods—consult a pediatrician promptly.
Treating Watery Eyes During Teething: What Helps?
Since watery eyes during teething stem from irritation rather than infection most times, treatment focuses on soothing discomfort rather than medicating tears directly.
Here are some effective care tips:
Soothe Gum Pain First
Relieving gum pain reduces overall facial irritation which may calm tear gland stimulation:
- Teething rings: Chilled (not frozen) rings provide counter-pressure easing soreness.
- Mild gum massage: Using clean finger gently on swollen areas helps circulation.
- Pain relievers: Pediatrician-approved doses of acetaminophen or ibuprofen if fussiness is severe.
Keeps Eyes Clean Without Irritation
Gently wipe away excess tears using soft cloths dampened with clean water—avoid rubbing harshly near sensitive skin.
Avoid using any eye drops unless prescribed by a doctor since unnecessary medications might worsen symptoms.
Avoid Triggers That Aggravate Irritation
Keep baby’s hands clean so they don’t introduce irritants when rubbing their face or eyes. Maintain good hygiene around feeding areas to prevent infections that mimic teething symptoms.
The Timeline: How Long Do Watery Eyes Last During Teething?
Watery eyes related to teething usually appear intermittently throughout active tooth eruption phases. These phases vary but generally follow this pattern:
- Eruption starts: Mild gum swelling with occasional watering lasting days.
- Main cutting phase: Increased drooling and irritability with more frequent watery episodes.
- Eruption completion: Symptoms gradually fade once tooth fully breaks through gums.
Typically, each tooth takes several days up to two weeks before emerging fully. Since infants get around 20 primary teeth over two years on average, episodes of mild watery eyes may recur multiple times but remain temporary.
| Eruption Stage | Description | Tear Symptoms Duration |
|---|---|---|
| Eruption Onset | Sore gums swell before tooth breaks surface. | A few days up to one week. |
| Main Cutting Phase | Tooth pushing through gum causes peak discomfort. | A few days with possible frequent tearing. |
| Eruption Completion | Tooth fully visible; tenderness subsides. | Tearing reduces gradually within days. |
The Role of Parental Observation & When To Seek Help
Parents play a crucial role spotting whether watery eyes relate solely to teething or signal something more serious. Close daily observation helps track symptom patterns:
- If watery eyes appear only during chewing/teeth-related fussiness without other eye issues—they likely stem from teething irritation.
- If accompanied by persistent redness, swelling around eyelids, thick yellow discharge—or worsening despite soothing efforts—medical evaluation is essential.
- If baby shows signs of systemic illness like high fever (>101°F), lethargy beyond normal fussiness—it’s time for prompt pediatric consultation regardless of presumed cause.
Early intervention prevents complications such as bacterial conjunctivitis or blocked tear ducts becoming chronic problems requiring specialized treatment.
The Science Behind Why Some Babies Get Watery Eyes While Others Don’t
Not every baby experiences watery eyes during teething because individual differences affect how inflammation impacts surrounding tissues:
- Nerve Sensitivity: Some infants have heightened trigeminal nerve sensitivity leading to stronger reflex tear responses.
- Anatomical Variations: Differences in lacrimal gland size/function influence tear production rates under stimulation.
- Crying Thresholds: Babies who cry more intensely might produce emotional tears adding to baseline watering caused by gum irritation.
Environmental factors such as dry air causing eye dryness might paradoxically increase reflex tearing during this period too.

Frequently Asked Questions
Can teething cause watery eyes in infants?
Yes, teething can cause watery eyes indirectly. The inflammation and discomfort in the gums can stimulate nearby nerves that influence tear production, leading to increased tearing or watery eyes as a side effect of teething.
Why does teething cause watery eyes along with other symptoms?
Teething triggers an inflammatory response that affects not only the gums but also nearby facial nerves. These nerves connect to tear glands, so irritation from teething can result in watery eyes along with drooling, fussiness, and gum swelling.
How does teething lead to eye irritation and watery eyes?
The inflammation during teething stimulates nerve pathways near the gums and eyes. This stimulation can cause reflex tearing. Additionally, drooling and rubbing around the eyes may irritate the skin, increasing tear production and watery eyes.
Are watery eyes a common symptom during teething?
Watery eyes can be a common but less recognized symptom of teething. While not every infant experiences it, many show increased tear production due to nerve stimulation and mild eye irritation linked to the teething process.
When should I be concerned if my baby has watery eyes during teething?
If watery eyes are accompanied by redness, swelling, discharge, or persistent discomfort beyond typical teething symptoms, it’s best to consult a pediatrician. Watery eyes alone from teething usually resolve as inflammation decreases.
Conclusion – Can Teething Cause Watery Eyes?
Yes—teething can cause watery eyes mainly due to nerve-related reflex tearing triggered by inflamed gums and facial sensitivity during this developmental phase. While not every infant experiences this symptom, it’s common enough that parents should expect occasional watering alongside classic signs like drooling and irritability.
Watery eyes linked solely to teething tend to be mild and transient without redness or discharge typical of infections. Careful soothing of gum pain combined with gentle eye hygiene usually resolves symptoms quickly without medical intervention.
However, persistent eye redness, thick discharge, fever spikes above normal levels, or worsening distress warrant prompt pediatric evaluation since these could indicate infection or other issues unrelated directly to teething.
Understanding this subtle but real connection helps parents stay calm when faced with unexpected symptoms during their child’s early months—and ensures babies get safe comfort while growing those precious first teeth!
