Teething gets blamed for a lot of things it does not cause

There is a short answer about teething and a useful one, and they are not the same. What follows is the useful one.

The timetable is loose

First teeth appear across a wide window, and a late first tooth is common and usually means nothing at all. The order tends to follow a rough pattern with a great many exceptions, and some babies are born with a tooth already through. Comparing with a cousin who had eight by the same birthday produces worry without producing information.

If no teeth have appeared by the age your health service flags, a dentist or health visitor can check, and the visit is usually reassurance.

What is genuinely associated

Drooling, gum rubbing, chewing everything, mild irritability and some disruption to sleep and feeding are the symptoms that hold up in the research. The effects are generally modest and cluster in the few days either side of a tooth breaking through, rather than running for weeks. That timing matters, because a fortnight of misery blamed on one tooth is usually about something else.

When it is going badly, discomfort is real even when it is mild, and a baby who is uncomfortable is entitled to be treated as such.

What is not

High fever, significant diarrhoea, vomiting and rashes beyond ordinary drool irritation are not established as teething symptoms. The coincidence is easy to make, because teeth arrive at exactly the age babies start meeting a large number of viruses.

When it is going badly, the cost of the assumption is that an illness gets attributed to a tooth and nobody looks at it. If a baby has a fever or seems unwell, that is a question for your health service, not for a teething chart.

What actually helps

Counter-pressure is the mechanism, which is why chewing on something firm gives more relief than anything soothing. A chilled teether, a clean finger or a cold flannel work on the same principle, and freezing solid is discouraged because it becomes hard enough to bruise gums. Amber necklaces have no evidence behind them and carry strangulation and choking risks, and several health bodies advise against them outright.

Teething gels and pain relief differ between countries, some ingredients are restricted for infants, and a pharmacist will tell you what is appropriate where you are.

Drool rash is a skin problem

Constant wetness on the chin and neck breaks down skin, which is why the rash follows the drool rather than the tooth. Patting dry rather than wiping, and a barrier ointment, treat the actual cause. A rash that spreads, blisters, or appears in a baby who is unwell is a different matter and worth showing to a professional.

Bibs changed often do more than any cream.

Every child is different, and so is every week.

Start brushing before it feels necessary

Brushing begins with the first tooth, and the habit is far easier to establish before a child has opinions about it. Fluoride guidance, including how much toothpaste and from what age, differs between countries, so follow your own dental service. Milk or juice in a bottle at night pools around new teeth and is one of the more common causes of early decay.

In practice, many countries offer free or subsidised dental care for children, and the recommended age for a first visit is earlier than most parents assume.

The takeaway

Give them something firm and cold, and stop letting a tooth take the blame for an illness.
