A drooly chin, a chewed-up sleeve, a suddenly fussy evening — baby teething is one of those milestones every parent braces for, but it rarely arrives exactly on schedule. Teeth can start pushing through anywhere from 3 to 14 months, and the symptoms are often more subtle (and less dramatic) than the reputation suggests. Here is what actually happens, in what order, and what genuinely helps.
This is general guidance based on widely used pediatric and pediatric-dental references. Always follow your own pediatrician's advice for your baby.
Teething timeline: which teeth come in, and when
Most babies get their first tooth between 6 and 10 months, but the normal range is wide. By around age 3, most children have a full set of 20 primary ("baby") teeth. The order is fairly consistent, even when the exact timing varies:
| Teeth | Typical age |
| Lower central incisors (bottom front) | 6–10 months |
| Upper central incisors (top front) | 8–12 months |
| Upper lateral incisors | 9–13 months |
| Lower lateral incisors | 10–16 months |
| First molars | 13–19 months |
| Canines | 16–22 months |
| Second molars | 23–33 months |
Bottom teeth almost always arrive before their upper counterparts, and each tooth tends to cause a short burst of symptoms — usually a few days before it emerges and easing once it breaks the surface. A single "episode" typically lasts around 3–8 days per tooth, though babies vary a lot in how much discomfort they show.
Real teething symptoms
These are the signs actually linked to a tooth on its way in:
- Increased drooling — often the earliest and most reliable clue
- Chewing and gnawing on hands, toys, or anything within reach
- Swollen, red or tender gums over the spot where the tooth is coming through
- Mild irritability or fussiness, more pronounced than usual
- Disrupted naps or night sleep, especially the night or two before a tooth breaks through
- Slightly reduced interest in feeding, if sore gums make sucking or chewing uncomfortable
Myths worth retiring: Teething does not cause a true fever, diarrhea, or vomiting, despite how often it gets blamed. Research consistently finds only a very small, temporary rise in temperature around teething — nothing close to a real fever. If your baby has a genuine fever (38°C / 100.4°F or higher) or digestive symptoms, treat it as a possible illness and check with your pediatrician rather than waiting it out as "just teething."
What actually helps
Simple, low-risk options work best:
- A chilled (not frozen) teething ring — cold, firm silicone rings soothe the gums; a fully frozen one can be too hard and even injure the gums
- A clean, cold, damp washcloth to chew on — an easy, always-available option
- Gentle finger massage — a clean finger pressed lightly along the gum line for a minute or two
- Extra cuddles and a bit more patience — comfort matters as much as any product on a rough day
- Age-appropriate pain relief when needed — for a genuinely uncomfortable night, ask your pediatrician about the correct dose of infant paracetamol or ibuprofen for your baby's age and weight
Track teeth as they come in — together
Trackeron lets you log teething symptoms, disrupted sleep and which tooth just came through, right alongside feeds and naps. Your partner or grandma can open the app and see exactly what's going on tonight — no re-explaining, no guessing which tooth is next.
How teething affects sleep and feeding
The two things parents notice most are a rockier night and a fussier feed. Sore, swollen gums can make sucking at the breast or bottle briefly uncomfortable, so it is common for a teething baby to feed for shorter stretches, pull off more often, or show less enthusiasm for a favourite meal for a few days — this usually passes once the tooth is through, and rarely lasts long enough to affect overall growth. Night waking is just as common: the ache tends to feel more noticeable when your baby is lying still and there are fewer daytime distractions, which is why teething nights often feel harder than teething days. A short return to more frequent night wake-ups during an active teething stretch is normal and is not the same as a sleep regression, even though the two can look alike from the outside.
What to avoid
Some traditional teething remedies carry real risks and are worth skipping entirely:
- Numbing gels and liquids with benzocaine or lidocaine — regulators including the FDA have warned these can cause a rare but serious blood condition (methemoglobinemia) in infants and young children, and are not recommended
- Amber teething necklaces or any teething jewelry — worn around the neck or wrist, these are a genuine choking and strangulation hazard, and there is no reliable evidence they relieve pain
- Homeopathic teething tablets or gels containing belladonna — some products have been subject to safety warnings and recalls over inconsistent, potentially unsafe ingredient levels
When to check with your pediatrician
Teething alone is not usually a reason to worry, but reach out if your baby has a genuine fever (38°C/100.4°F or higher), refuses feeds or fluids for an extended stretch, seems unusually unwell rather than just fussy, or hasn't cut a first tooth by around 18 months.
Frequently asked questions
Should I brush teeth as soon as the first one appears? Yes — start brushing with a soft, small infant toothbrush and a rice-grain smear of fluoride toothpaste as soon as the first tooth erupts, twice a day.
Can teething and a growth spurt happen at the same time? Yes, and it can be hard to tell them apart — both can disrupt sleep and appetite. Tracking patterns over a few days (drooling and gum swelling point to teething; increased hunger points to a growth spurt) usually clarifies which is going on.
The bottom line: teething is uncomfortable but rarely serious, follows a fairly predictable order, and responds well to simple, safe comfort measures. Watch for the real signs — not the myths — and you'll know when it's teething and when it's worth a call to the pediatrician.
