When Do Babies Start Teething? Signs, Timeline & What to Expect

One day, your baby is all smiles and gums. The next day, there's a tiny white edge poking through, and suddenly you're googling at 2 a.m., wondering why your usually cheerful baby is gnawing on everything in sight. 

Welcome to teething: a milestone every parent looks forward to and one that almost always arrives with a side of drool, fussiness, and sleepless nights.

The good news? Once you know what's actually happening beneath those gums and what's coming next, teething stops feeling like a mystery and starts feeling manageable. Here's everything you need to know: the signs to watch for, the order in which teeth typically arrive, and how to get your baby (and yourself) through it comfortably.

Signs of Teething

What teething actually looks and feels like

So what does it look like when one of those hidden teeth decides it's time to make an appearance? As it nears the surface, it presses against and irritates the gum tissue above it, and the result is a fairly predictable set of symptoms:

• Increased drooling: often the earliest sign, sometimes starting weeks before a tooth appears. Babies drool heavily during teething because the emerging teeth irritate and stimulate the salivary glands, causing an overproduction of saliva. This excess saliva acts as a natural, soothing lubricant for tender, inflamed gums and helps protect their mouth. 

• Swollen, tender, or bluish-red gums: you may even see or feel a hard bump under the gum

• Constant chewing, gnawing, or gum-rubbing on fingers, toys, or anything within reach as the pressure temporarily relieves the discomfort

• Drool rash: redness or chapping around the mouth, chin, and neck caused by constant moisture

• Irritability or clinginess, often worse in the evenings

• Disturbed sleep, even in babies who normally sleep through the night

• Ear-pulling or cheek-rubbing on the side of the emerging tooth, due to shared nerve pathways

• Mild rise in temperature: generally under 38°C (100.4°F), caused by localised gum inflammation

• Reduced interest in feeding: sucking creates pressure on sore gums

What teething does NOT cause

Despite popular belief, research from major paediatric bodies has consistently found that teething does not cause high fever, diarrhoea, vomiting, persistent cough, or body rashes. These symptoms are common in infancy simply because teething (which lasts on and off for two years) often overlaps with other minor illnesses by coincidence. If your baby has a fever above 38.3°C (101°F) or any of these symptoms, treat it as a separate illness and consult your paediatrician, don't assume it's "just teething."

Timeline: When Do Teeth Appear?

If there's one question every parent asks, it's "when?" The honest answer is: it depends, but there's a pattern worth knowing. Most babies get their first tooth between 4 and 7 months, though anywhere from 3 to 12 months is considered within the normal range. After that first tooth, new ones tend to follow roughly every 1–2 months. Sometimes one at a time, sometimes two or three in quick succession after a quieter stretch. By around age 3, most children have their full set of 20 primary teeth.

A few patterns worth knowing:

• Lower teeth usually arrive first: the lower central incisors are typically the very first teeth, though in about 1 in 10 babies, the upper central incisors appear first instead.

• Molars and canines erupt later and tend to be more uncomfortable, simply because they're larger and have to push through more gum tissue.

• Second molars are usually the last to arrive, often between 2 and 3 years of age.

• Premature babies often teethe a little later than their adjusted age would suggest, and this is completely normal.

What Parents Should Know

Knowing what's happening is one thing, getting through it is another. Here's how to make this stretch easier for your baby (and calmer for you), plus a few things worth avoiding altogether.

Easing the discomfort

• Chilled (not frozen) teething rings: the cold causes mild numbing and constricts blood flow to the inflamed area, reducing swelling and discomfort. Frozen rings can be too hard and bruise the gums.

• Clean finger massage: gently rubbing the gums with a clean finger applies counter-pressure, which often brings quick relief.

• Cold, damp washcloth: place it in the fridge (not freezer) for 15–20 minutes, then let your baby chew on it. The texture also helps "scratch the itch" of an emerging tooth.

• Teething biscuits or rusks: only once your baby has started solids, can sit upright, and is supervised throughout.

• Pain relief medication: paracetamol or ibuprofen (age-appropriate, correctly dosed) can help on particularly difficult days, but only after checking with your paediatrician.

• Extra cuddles and feeds: comfort feeding (breast or bottle) can be soothing even if your baby isn't drinking much; just watch for gum sensitivity making this uncomfortable too.

What to avoid

• Teething gels containing benzocaine or lidocaine: these numbing agents have been linked to a rare but serious blood condition in infants and are not recommended for children under 2.

• Amber teething necklaces or bracelets: marketed as natural remedies, but they pose genuine choking and strangulation risks and have no proven benefit.

• Frozen, rock-hard teething toys: can bruise or injure sensitive gum tissue.

• Hard, raw foods (like whole carrots or apple chunks) given unsupervised: choking hazard for babies still learning to chew.

• Homeopathic teething tablets: some have been recalled in the past due to inconsistent ingredient levels; check with your paediatrician before using any.

When to start brushing

Start brushing as soon as the first tooth appears, usually around 6 months, and no later than the first birthday. Guidelines from American Academy of Pediatric Dentistry recommend:

• A soft-bristled, infant-sized toothbrush

• A smear (roughly the size of a grain of rice) of fluoride toothpaste

• Brushing gently, twice a day

• Once teeth start touching each other, introducing flossing to clean between them

This is also where choosing the right baby oral care products matters. Look for brushes that are soft, age-appropriate, easy to hold, and gentle on delicate gums. STIM Junior make this transition easier with stage-wise oral care products designed to grow with every tooth, from the Infant Kit (finger brush, 0-6 months) for those very first gums, to the Toddler Kit (silicone brush, 6-24 months), to the Baby Toothbrush (1-3 years) built for little hands learning to brush independently, and more. Each product is dentist-recommended and designed so parents are never guessing what to use at each stage. 

Other key points

• Wipe gums even before teeth appear: using a clean, damp gauze pad or soft cloth after feeds removes milk residue and builds an oral hygiene routine from day one.

• Avoid bottle-feeding at bedtime: milk pooling around the gums overnight is one of the leading causes of early childhood tooth decay, sometimes called "baby bottle tooth decay."

• Schedule the first dental visit by age 1, or within six months of the first tooth erupting. Early visits are mainly about establishing a routine and catching issues early, not about treatment.

• Watch for delayed eruption: if no teeth have appeared by 18 months, mention it at your next paediatric or dental visit.

• Discoloured or unusually shaped teeth at eruption should also be flagged to a dentist, as this can sometimes indicate enamel development issues that are easier to manage when caught early.

Final Thoughts

Teething isn't a single event, it's a journey that unfolds in stages over nearly three years, and every baby moves through it at their own pace. Some sail through with barely a grumble; others need a little extra patience, cuddles, and chilled teething rings along the way. Either way, what matters most is consistency: keeping those tiny gums and emerging teeth clean from the very start sets the foundation for healthy oral habits that last well beyond the toddler years.

If something feels off, a tooth that's very late, oddly shaped, or accompanied by symptoms that don't fit the usual teething picture, trust your instincts and check in with your paediatrician or dentist. Otherwise, ride it out one tooth at a time. Before you know it, you'll have a baby with a full, gummy grin turning into a full set of pearly whites.

FAQs

1. My baby is 9 months old with no teeth yet. Should I be worried? 

Not necessarily. Some babies don't get their first tooth until 12–14 months. If there's no sign of any tooth by 18 months, it's worth discussing with your paediatrician.

2. Can teething affect appetite for breastfeeding or bottle-feeding?

 Yes, sore gums can make babies less interested in feeding for a few days. Offering shorter, more frequent feeds can help during this time.

3. Is it normal for a tooth to take weeks to fully come through? 

Yes. A tooth can take several weeks to break through the gum completely, and discomfort often comes in waves rather than constantly.

4. Do girls and boys get teeth at different times? 

There's a very slight tendency for girls to get teeth marginally earlier than boys, but the difference is minor and not something to worry about.
