Toddlers chew on everything because their mouths are powerful sensory tools, second only to their hands for gathering information about the world. Between 18 and 24 months, mouthing objects is a completely normal part of development. Your toddler’s brain is using chewing to learn about size, shape, hardness, and texture in ways that touching alone can’t provide. But exploration isn’t the only driver. Teething pain, emotional self-soothing, and sensory needs all play a role, sometimes at the same time.
The Mouth as a Learning Tool
Your toddler is in what developmental specialists call the sensorimotor stage, where physical interaction is the primary way of understanding objects. The mouth acts like a second pair of eyes, sending the brain detailed information about whatever your child picks up. Is it squishy or hard? Smooth or bumpy? Big enough to fit between the teeth? These are questions a toddler’s mouth answers faster and more precisely than their still-developing fine motor skills can.
This kind of oral exploration typically peaks between 18 and 24 months, then gradually fades. Most children move past the “taste everything” phase by age 2, though some take longer. A slower timeline isn’t usually a sign of a problem. Children develop at their own pace, and interest in mouthing objects varies widely from one child to the next.
Teething Can Extend the Chewing Phase
If your toddler seems to chew with extra intensity, teething is a likely explanation. The first molars come in between 13 and 19 months, and the second molars arrive between 23 and 33 months. Molars are broader and flatter than the front teeth that came in during infancy, and pushing through the gums can cause significant swelling and tenderness. Chewing on firm objects applies counterpressure to the gums, which temporarily dulls the discomfort.
Teething-related chewing often looks different from exploratory mouthing. You might notice your toddler gnawing repeatedly on one side of their mouth, drooling more than usual, or gravitating toward harder objects like wooden blocks or furniture edges rather than sampling a variety of items. This pattern typically lines up with the molar eruption timeline and resolves once the teeth break through.
Chewing as Self-Regulation
Chewing isn’t just about learning or teething. It’s also a calming strategy. The jaw is one of the most powerful muscle groups in the body, and biting down on something sends a strong wave of proprioceptive input to the brain. Proprioception is your body’s sense of where it is in space and how much force it’s using. That deep-pressure feedback from the jaw has a regulating effect on the nervous system, similar to how a tight hug or heavy blanket can help a child settle down.
Toddlers who chew more when they’re tired, overstimulated, anxious, or transitioning between activities are likely using their mouths to self-soothe. Their brains are overwhelmed by sensory input from the environment, and the rhythmic, repetitive motion of chewing helps filter out the noise. This is normal behavior, not a disorder. Many adults do the same thing unconsciously: chewing gum during stressful meetings, biting pen caps, or clenching their jaw while concentrating.
When Chewing Signals Something More
In most cases, a toddler who chews on everything is doing exactly what their developmental stage predicts. But there are a few situations worth paying attention to.
Children with developmental delays may continue mouthing objects well past age 2 because they’re still working through the sensorimotor stage at their own pace. If your child is also delayed in other areas like speech, walking, or social interaction, the extended mouthing could be part of a broader pattern worth discussing with your pediatrician.
Some children have heightened sensory processing needs and actively seek oral input more than their peers. You might notice them chewing on shirt sleeves, collars, fingers, or hair in addition to toys and household objects. This kind of oral sensory seeking isn’t inherently concerning, but if it’s intense enough to damage teeth, cause skin breakdown on fingers, or interfere with daily activities, an occupational therapist can help.
Pica, the persistent eating of non-food items like dirt, paint chips, or paper, is a separate condition. It’s not diagnosed in children under 2, because mouthing non-food items is developmentally normal at that age. After age 2, if a child consistently swallows non-food materials for a month or more, it may be linked to iron or zinc deficiency and warrants a medical evaluation.
Household Hazards Worth Checking
A toddler who chews on everything turns ordinary household surfaces into potential exposures. The most significant risk is lead paint. Lead-based paints were banned for residential use in 1978, but roughly 29 million housing units in the U.S. still contain lead-based paint hazards, and about 2.6 million of those are home to young children. Windowsills, door edges, and baseboards are common chewing targets, and if your home was built before 1978, these surfaces may contain lead. Children can be exposed by chewing painted surfaces directly, eating flaking paint chips, or even breathing in lead-contaminated dust.
Choking is the other major concern. The U.S. Consumer Product Safety Commission defines a choking hazard as any object that fits entirely inside a small parts cylinder, which approximates the size of a young child’s fully expanded throat. That includes whole small toys, detachable parts, and pieces that break off during normal play. A good rule of thumb: if it can pass through a toilet paper roll, it’s too small for a child under 3 to have unsupervised access to.
Practical Ways to Redirect the Chewing
You don’t need to stop the chewing. You need to make it safe. Giving your toddler appropriate things to chew on satisfies the sensory need without the risks that come with gnawing on furniture, cords, or random objects off the floor.
For teething discomfort, chilled (not frozen) teething rings or washcloths provide both counterpressure and a soothing temperature. For sensory-seeking chewers, purpose-built chew tools come in a range of shapes and textures. Some have long, slender extensions that reach the back molars where the proprioceptive input is strongest. Others feature textured surfaces with bumps or ridges that add extra sensory feedback. Look for tools made from food-grade silicone that are free of common allergens and small parts.
Crunchy and chewy foods also channel the urge productively. Carrot sticks, apple slices, dried mango, or bagels give the jaw the deep-pressure workout it’s looking for. Offering these as snacks during high-stimulation moments (after daycare pickup, during errands, before nap transitions) can preempt the urge to chew on less desirable items.
For toddlers who chew more when overwhelmed, reducing sensory input in the environment can lower the drive. Dimming lights, turning off background noise, or moving to a quieter room gives the brain less to process, which means less need to self-regulate through the mouth. Pairing a calming environment with an acceptable chew option teaches your child to recognize and meet their own sensory needs over time.
