When do Babies Start Teething & How to Relieve Pain

Updated: Jun 1, 2023

So your little angel has turned into an unsettled, drooling vampire – unsettled at night, poor

feeding, fingers in the mouth, biting everything in sight and generating a tsunami of saliva.

‘Could it be teething?’ you ask, and ‘how would you know?’ Well, these eternal questions

are right up there with ‘What is the meaning of life?’ and ‘How to fix pandemics?’

When do babies teeth come through?

First, let’s go back to the basics. At birth, all babies have all their primary teeth hidden

under their gums, just waiting to burst out and wreak havoc. They usually start erupting

between 4 to 7 months. By now, I’m sure all you new parents would agree that the Golden

The rule about anything to do with pregnancy, childbirth and babies is that there are no golden rules. Some sprogs start teething anywhere from 3 months to well over a year, and the occasional newborn even arrives on day one with a tooth or two on display.

The two lower central incisors usually arrive first, followed by the four upper central fangs,

the lower side incisors, then the molars (the grinders) and finally, the pointy upper eye teeth

- 20 little baby teeth all up, usually by the third birthday. (Not that anyone is having big

birthday parties just now.) Then around three years later, those milk teeth start to shed and

the 32 permanent pearly whites begin to come through, with nothing to it. Piece of cake, really. (Well, not too many pieces of cake.)

When do babies start teething?

You won’t be surprised to hear that they all do it differently. Some babies just wake up one morning with a bright shining tooth. Happy as Larry. Others seem to absolutely sweat out each one with uber drama and great distress. In theory, each teething episode takes around 8 days i.e. 4 days of painful lead-up, then the great eruption and another 3 days of misery after. However, some babies go for the long slow build-up for some weeks before the big day. All the signs are there but nothing to see.

Most teething babies get a little cranky and fussy, don’t feed as well, and have more dirty

nappies, don’t sleep as well (it’s harder to ignore your aching gums lying in your cot at night

with no distractions), might pull the ear on the same side of the tooth coming through, stick

their fingers in their mouth, drool excessively and chew on anything they can get their hands


Do they get a temperature? The answer is no. Well, not much. Some babies do seem to develop a low-grade fever when they are teething, but anything over 37.5 or 38 is likely to be due to an infection, viral or bacterial. What about rashes? Sure, some little ones get a bit rashy, especially on the face and chin and upper chest, but teething usually doesn’t cause more generalised rashes. Lethargic and floppy? Certainly not. Teething bubs are more likely to be annoyed and agitated. So if your baby has a high temp, persistent vomiting/diarrhoea, an odd rash or seems flat and out of it, don’t blame it on those toothy pegs - time to seek

medical advice.

How to soothe a teething baby

No simple solution. It's best to wipe the face with a cloth to mop up the drool, rub your baby’s gums with a (clean) finger, give him/her something to bite on, like a cold teething ring or toothbrush, something firm to suck on, like a (sugar-free) rusk and prepare mushier foods. If your bub still seems pretty unhappy and teething is the obvious cause, then it’s worth a dose of paracetamol, or ibuprofen (if over 6 months).

We medicos are not crazy about teething gels because we feel they don’t really help and

usually contain aspirin, which we avoid in young children, and local anaesthetic which doesn’t absorb well via the gums. Also, any benefit rarely justifies the trauma of trying to rub

it on! Ditto about the ubiquitous amber bead necklaces, which are supposed to release a

soothing oil when in contact with warm skin. They can be dangerous if babies chew on them

or get them tangled up, ie. there is a small risk of choking. So, don’t let your baby sleep with

one of these necklaces on.

Taking care of baby teeth

I mean, the Tooth Fairy will end up with them anyway, right? The answer is, of course, you do need to take care of your baby's teeth. It’s important to get into the habit of cleaning them from the start. Mum or dad needs to brush these new teeth twice a day with water and a small soft toothbrush. After 18 months you can start using a small amount of appropriate toothpaste. From around 2, kids can start holding the toothbrush themselves but need adult supervision until they are 8 or so. And, of course, we love flossing and fluoride and we don’t love sugary snacks and going to sleep with a bottle in situ. Even baby teeth can develop decay, which can result in other health problems and early loss of those teeth can result in overcrowding when the permanent teeth arrive.

So, the bottom line is, the main thing that teething produces is …teeth.
