Babies drool during teething because increased saliva helps soothe gums and signals oral development.
The Science Behind Baby Drooling During Teething
Teething is a critical developmental stage for infants, typically starting around 4 to 7 months of age. One of the most noticeable signs during this period is excessive drooling. But why does this happen? The answer lies in the body’s natural response to the discomfort caused by emerging teeth.
When a baby’s teeth start breaking through the gums, it can cause irritation and mild inflammation. To counter this, the salivary glands ramp up production of saliva. This extra moisture acts as a natural lubricant, soothing the tender gums and reducing friction from chewing or rubbing. Saliva also helps protect against infection by washing away bacteria that might enter through tiny breaks in the gum surface.
Moreover, babies haven’t yet developed full control over swallowing saliva, so it tends to pool and spill out of their mouths. This combination of increased saliva production and immature swallowing reflexes results in noticeable drooling.
How Teething Triggers Increased Saliva Production
The eruption of teeth stimulates nerve endings in the gums, which sends signals to the brain to activate salivary glands. This process is part of a reflex arc designed to protect delicate oral tissues. Increased saliva not only soothes but also aids digestion by preparing enzymes that will soon be needed when solid foods are introduced.
Saliva contains important enzymes like amylase that begin breaking down carbohydrates right in the mouth. This early digestive aid is crucial as babies transition from milk to more complex diets.
Common Signs Accompanying Drooling During Teething
Drooling rarely happens alone during teething; several other signs usually appear alongside it:
- Gum Swelling: Gums often look red and puffy where teeth are about to emerge.
- Irritability: Babies may become fussy or restless due to gum discomfort.
- Biting and Chewing: Infants tend to gnaw on toys or fingers to relieve pressure on their gums.
- Slight Temperature Rise: A mild increase in body temperature can occur but high fever is uncommon.
These symptoms combined with drooling form a clear picture that teething is underway.
Why Drooling Can Be Messy but Normal
Excess saliva production means babies often have wet clothes, bibs, and bedding. While this can be frustrating for parents, it’s a normal part of development. The skin around the mouth may become irritated or chapped from constant moisture, so using gentle barrier creams or keeping the area dry helps prevent rashes.
Drooling also encourages babies to explore with their mouths since wet surfaces feel different and stimulate sensory development.
The Role of Oral Motor Development in Drooling
Babies develop control over their mouth muscles gradually. Early on, they lack coordination between breathing, swallowing, and managing saliva flow. This immaturity causes saliva overflow outside the mouth during teething when production spikes.
As oral motor skills improve over months, drooling decreases naturally even if teeth continue erupting. This progression reflects broader neuromuscular development essential for feeding and speech later on.
How Feeding Patterns Influence Drooling
Breastfeeding or bottle-feeding requires different oral muscle actions than eating solids. When babies start teething and drooling more, they may show changes in feeding habits—sometimes refusing food due to gum soreness or sucking less vigorously.
Parents can support comfort by offering chilled teething rings or soft foods that don’t irritate gums while maintaining hydration and nutrition.
Comparing Drooling Levels: Teething vs Non-Teething Babies
Not all infants drool equally; some produce more saliva even without teething stimuli due to individual variations in salivary gland activity or oral sensitivity.
| Baby Stage | Average Saliva Production (ml/day) | Drooling Frequency |
|---|---|---|
| Pre-Teething (0-3 months) | 20-30 ml | Low – occasional dribble |
| Active Teething (4-12 months) | 50-100 ml | High – frequent drooling & spills |
| Post-Teething (12+ months) | 30-40 ml | Moderate – controlled swallowing improves |
This table highlights how saliva output peaks during active teething phases then settles as babies gain better oral control.
Caring Tips for Managing Drooling During Teething
Parents can take several steps to ease discomfort caused by teething drool:
- Keepskins Dry: Change bibs frequently; gently pat around mouth instead of rubbing.
- Use Soothing Remedies: Cool teething rings or damp washcloths provide relief when chewed.
- Avoid Irritants: Skip acidic foods or harsh soaps near the mouth area.
- Dab Protective Creams: Apply barrier ointments like petroleum jelly or zinc oxide sparingly.
- Mild Pain Relief: Consult pediatricians about appropriate use of infant acetaminophen if fussiness worsens.
These simple measures help minimize skin irritation while supporting baby’s comfort through this phase.
The Importance of Monitoring Symptoms Beyond Drooling
Although drooling is normal with teething, parents should watch for signs that suggest other issues such as infections or allergies:
- Persistent high fever (above 101°F/38.3°C)
- Difficulties breathing or swallowing
- Poor feeding lasting more than a day or two
- Bloody or pus-filled gum sores instead of typical swelling
If any of these occur alongside excessive drooling, professional medical advice should be sought promptly.
The Developmental Benefits Hidden in Drooling Episodes
Though messy and sometimes annoying, drooling plays a role beyond soothing gums—it supports oral sensory learning vital for speech development later on. Saliva keeps oral tissues moist which enhances taste perception and tactile feedback inside the mouth.
Babies experiment with sounds by babbling while managing saliva flow; this practice strengthens muscles involved in talking down the road.
Drooling as an Indicator of Healthy Growth
In many ways, excessive drooling signals your baby’s body is progressing normally through growth milestones:
- The nervous system responds correctly by activating salivary glands at appropriate times.
- The immune system uses saliva’s protective enzymes against germs entering through new gum openings.
- The digestive system prepares early enzymes needed for solid food breakdown.
Far from being just a nuisance, drool marks healthy developmental steps during infancy’s complex changes.

Frequently Asked Questions
Why do babies drool when teething?
Babies drool during teething because their salivary glands produce more saliva to soothe irritated gums. This extra saliva helps reduce friction and discomfort as new teeth break through the gum line.
Additionally, babies have not yet developed full control over swallowing saliva, causing it to spill out of their mouths.
How does teething cause increased drooling in babies?
Teething stimulates nerve endings in the gums, signaling the brain to activate salivary glands. This natural reflex increases saliva production to protect and soothe sensitive gum tissue.
The increased moisture also helps wash away bacteria and prepare the mouth for solid foods.
What are common signs that babies drool because of teething?
Along with drooling, babies often show gum swelling, irritability, biting or chewing on objects, and sometimes a slight temperature rise. These signs indicate that teething is causing discomfort and increased saliva.
Why is drooling messy when babies are teething?
The excess saliva produced during teething often soaks clothes, bibs, and bedding. This messiness is normal and part of the developmental process as babies adjust to new oral sensations.
Parents should keep skin dry to prevent irritation around the mouth area.
Can drooling during teething help a baby’s development?
Yes, drooling aids development by keeping gums moist and reducing discomfort. Saliva also contains enzymes that start breaking down food, helping babies transition from milk to solid foods.
This natural process supports oral health and digestion during early growth stages.
Conclusion – Why Do Babies Drool When Teething?
Drooling during teething happens because babies produce extra saliva to soothe irritated gums as new teeth push through. Their still-developing ability to swallow means this saliva often escapes their mouths causing noticeable dribbles. Alongside other common symptoms like gum swelling and irritability, drooling serves both as a natural pain relief mechanism and an indicator of healthy oral growth.
Understanding why babies drool when teething helps parents stay patient through this messy phase while providing practical care tips that ease discomfort and protect delicate skin. Rather than just being bothersome wetness, those little drips are signs your baby’s body is doing exactly what it should—growing strong one tooth at a time.
