Does Teething Really Stop Babies Sleeping?

What teething is published as causing

The lists are shorter than the reputation. The NHS says teething symptoms include a sore, red gum where the tooth is coming through, a mildly raised temperature of less than 38C, one flushed cheek, a rash on the face, rubbing the ear, dribbling more than usual, gnawing and chewing, and being more fretful than usual.

The American Academy of Pediatrics is similar and adds a ceiling: teething may occasionally cause mild irritability, a slight rise in temperature but not over 38.3C, excessive drooling and a desire to chew on something hard, and more often, swollen and tender gums around the new tooth.

The sentence that reframes the whole question

The AAP writes: "If your child seems particularly miserable or has a fever higher than 101 degrees Fahrenheit (38.3 degrees Celsius), it's probably not from teething. You should consult your pediatrician." The NHS makes the same move from the other direction, noting that a temperature of 38C or above is not caused by teething.

That is the answer to the night-waking question in one line. Teething can make a baby fretful, and a fretful baby settles less easily, so it can plausibly account for a few unsettled nights around a tooth arriving. It is not published as an explanation for a fortnight of hourly waking, and treating it as one means an ear infection, a cold, reflux or a genuine change in sleep needs goes unexamined for two weeks.

Teeth take months, and waking does not track them

The AAP puts the usual start at about four to seven months and says the timing varies a lot. Teeth continue arriving through the second and third years. Any explanation that is available every night for two years is not a diagnosis; it is a coincidence with good marketing.

What is safe to do at night

The NHS lists what helps: something hard to chew on, such as a teething ring; a teething ring cooled in the fridge, never the freezer, and never tied around your baby's neck; gently rubbing the gums with a clean finger; and if your baby is six months or older, pieces of cool, hard fruit or vegetable to gnaw on under supervision, though not at night in a cot.

On medicines, the NHS says sugar-free painkillers made for babies of your child's age can be used and tells you to follow the instructions that come with them. This page does not give amounts. If you are unsure whether a medicine is suitable or how much to give, ask a pharmacist, health visitor or GP, and read the label rather than any website.

What health bodies tell you not to use

The AAP is direct. Never use teething gels to numb the gums, because in rare cases they can poison babies' blood cells and stop them carrying oxygen. Homeopathic teething tablets provide no benefit and in some cases have been made with potentially harmful toxins. Amber teething necklaces do nothing at all for pain and have caused cases of choking and strangulation. The AAP also notes that teethers you freeze get too hard and can do more harm than good.

The safer-sleep point sits underneath all of this. The Lullaby Trust's clear-cot advice means nothing goes into the sleep space with your baby — no teething necklace, no amber beads, no teething ring left in the cot, no comforter soaked in gel. Never leave anything around a baby's neck, and never leave a teething toy in the cot for a sleeping baby.

What to do about the waking itself

Treat it as a night waking, because that is what it is. Ireland's HSE publishes the script: soothe by talking softly rather than loudly, feed if hungry, use a dim yellow or red night light rather than a bright or blue one, avoid screens, do not change the nappy unless it is dirty, and put your baby back into the cot drowsy but awake, on their back. It also says not to leave a baby crying for longer than a few minutes.

When it is not teething

Look for another explanation if the waking comes with a temperature of 38C or above, pulling at one ear with distress, a cough that worsens at night, feeding less than usual, diarrhoea, or a baby who cannot be consoled at all. Ear infections in particular are worse lying down and are commonly mistaken for teeth. The NHS asks you to see a GP if your child has earache with a high temperature, is being sick, or if fluid is coming from the ear.

Why the teething and sleep link is hard to study

Part of the reason no health body attributes long stretches of broken sleep to teething is that the timing makes it almost impossible to separate. Teeth arrive across the same months as the biggest changes in infant sleep, the start of solids, the first colds from nursery, and separation anxiety. Anything that happens continuously for two years correlates with everything. The Lullaby Trust and Basis both describe infant sleep as individual, variable and prone to periods of more waking without an identifiable cause, which is a more honest description of most teething fortnights than the tooth is. That does not mean your baby is not uncomfortable; it means treating comfort and treating the sleep are separate jobs.

When to ask

Speak to your health visitor, public health nurse or GP if the unsettled nights last more than a few days, if your baby has a temperature of 38C or above, if they are off their feeds, if there is ear pain or discharge, or if they are inconsolable rather than grumbly. Call 999 if your baby is limp, very hard to wake, or has a rash that does not fade when you press a glass against it.
