A 4-month-old who’s drooling nonstop, gnawing on everything, and fussier than usual is likely starting to teethe. The lower two front teeth typically push through first, and while some babies don’t show signs until 6 months or later, 4 months is a perfectly normal time for the process to begin. The good news: most teething discomfort responds well to simple, hands-on remedies you can start right now.
Recognizing Teething at 4 Months
Teething symptoms can look a lot like general fussiness or even illness, so it helps to know what’s actually teething-related. The most reliable signs are red, swollen gums where a tooth is working its way through, a noticeable increase in drooling, and constant chewing or gnawing on hands, toys, or anything within reach. Your baby may also have one flushed cheek, rub or pull at their ear on the same side as the emerging tooth, sleep more poorly than usual, or develop a mild facial rash from all the extra saliva.
A slight rise in body temperature is common during teething, but it stays below true fever range, generally between 98 and 100.3°F. If your baby’s temperature reaches 100.4°F or higher, that points to an illness rather than teething. The same goes for persistent coughing with congestion or ear pulling that lasts more than a day or two, especially alongside a high temperature. Those symptoms warrant a call to your pediatrician.
Gum Massage: The Simplest Relief
Rubbing your baby’s gums with a clean finger or a piece of damp gauze is one of the most effective things you can do. The pressure directly counteracts the aching sensation of a tooth pushing up through the tissue. Aim for about two minutes of gentle, firm rubbing along the swollen area. You can do this as often as your baby seems to need it, and both the FDA and the American Academy of Pediatrics recommend it as a first-line approach.
Many parents find that gum massage works especially well right before feedings or naps, when discomfort tends to peak. If your baby resists a bare finger, try wrapping it in a cool, damp washcloth for a slightly different texture and temperature.
Cold and Texture: What Works Best
Cold helps reduce gum inflammation, and textured surfaces give your baby something satisfying to chomp on. The combination is the sweet spot for teething relief at this age. A few approaches that work well for 4-month-olds:
- Chilled washcloths. Wet a clean washcloth, wring it out, and place it in the refrigerator (not the freezer) for 15 to 20 minutes. The soft, cold fabric is easy for small hands to grip and safe to gnaw on.
- Refrigerated teething rings. Water-filled teething rings stored in the fridge provide both cold and counterpressure. Avoid freezing them, since frozen rings become too hard and can hurt tender gums.
- Textured silicone teethers. Silicone teethers with bumps or ridges give your baby varied textures to explore. Look for ones with handles sized for a 4-month-old’s grip.
- Knotted cloth. A clean muslin or burp cloth tied into a knot makes an effective, no-cost teether. You can dampen and refrigerate it for extra soothing power.
- Teething mitts. At 4 months, many babies haven’t mastered holding objects to their mouths consistently. A teething mitt that fits over their hand lets them chew without needing to grip anything.
Whichever option you choose, refrigerate rather than freeze. Frozen teethers and washcloths can bruise or irritate already-sensitive gums. Chilled pacifiers also work if your baby already takes one.
Managing the Drool
Teething drool is relentless, and if it sits on your baby’s skin, it causes a red, bumpy rash on the chin, cheeks, neck folds, and chest. Preventing drool rash is easier than treating it once it appears.
Keep a clean, dry burp cloth nearby and gently blot (don’t rub) saliva from your baby’s face throughout the day. Check the neck folds and chest where drool pools, especially after feedings and naps. A bib helps keep clothing dry and reduces skin contact with moisture. Swap it for a fresh one as soon as it gets damp.
If a rash does develop, wash the area gently with warm water twice a day and pat it completely dry with a soft cloth. Skip medicated soaps, which can make the irritation worse. Once the skin is dry, apply a thin layer of petroleum jelly or a healing ointment like Aquaphor. This creates a barrier between your baby’s skin and the constant stream of saliva, allowing the rash to heal underneath. Most drool rashes clear up within a few days with consistent care.
Pain Medication: What’s Safe at 4 Months
For nights when nothing else is cutting it, infant acetaminophen (the liquid form, 160 mg per 5 mL) can help. However, for children under 2, you should check with your pediatrician before giving it so they can confirm the right dose based on your baby’s current weight. There’s no standard over-the-counter dosing chart for this age group, and getting it right matters.
Ibuprofen is not safe for babies under 6 months old, so it’s off the table for a 4-month-old entirely.
Reserve medication for the toughest moments, like when pain is clearly disrupting sleep or feeding despite other comfort measures. Most teething discomfort is manageable with the physical techniques above.
Products to Avoid
Some widely marketed teething products carry real risks for infants. Topical numbing gels containing benzocaine or lidocaine should not be used on babies. The FDA has issued warnings about these products because they can cause a rare but serious blood condition that reduces the amount of oxygen carried through the body.
Amber teething necklaces and other teething jewelry are also unsafe. The FDA issued a formal warning in 2018 after receiving reports of children choking on beads that broke loose, including the death of an 18-month-old strangled by an amber necklace during a nap. The AAP recommends that infants not wear any jewelry at all. The risks of strangulation and choking apply whether the necklace is worn during sleep or supervised play.
Frozen vegetables like carrot sticks are sometimes suggested as teethers, but for a 4-month-old who doesn’t yet have the ability to manage solid pieces in their mouth, these pose a choking hazard. Stick with options that can’t break into small pieces.
What to Expect Over the Coming Weeks
Teething isn’t one continuous stretch of misery. The worst discomfort typically hits in the days right before and right after a tooth breaks through the gum surface, then settles down until the next tooth starts moving. Your baby’s two bottom front teeth will likely appear first, followed eventually by the two top front teeth.
Some days your baby will seem completely unbothered, and other days the fussiness will return. This on-and-off pattern is normal and can continue for months as additional teeth emerge. Having a few go-to comfort strategies ready, like a chilled washcloth in the fridge and a teething mitt in the diaper bag, makes it easier to respond quickly when a rough patch hits.
