Most babies start teething somewhere between 4 and 10 months, but there's a wide normal range. The first tooth to come through is usually a lower front tooth, with the upper front teeth often appearing a couple of months later.
Teething can come in waves — a difficult few days, then a quiet stretch. Many parents notice symptoms a few days before they can see or feel the tooth.
- Dribbling more than usual
- Chewing on hands, toys, or the side of the cot
- Sore or swollen-looking gums
- One flushed cheek
- Mild fussiness or unsettled behaviour
- Slightly disturbed sleep
- A small white or sharp point visible under the gum, or you can feel it

- Fever, vomiting, diarrhoea, or a rash — these are unlikely to be teething
- Poor feeding or unusual drowsiness
- Baby seems very unwell or you feel something is not right
- Persistent ear-pulling with other signs of illness — could be an ear infection rather than teething
Frequently asked questions
When do babies usually start teething?
Teething often starts somewhere between 4 and 10 months, but it varies widely. Some babies cut their first tooth earlier, others much later. The first tooth to appear is usually a lower front tooth.
What are the signs my baby is teething?
Dribbling more than usual, chewing on hands and toys, sore or swollen-looking gums, one flushed cheek, mild fussiness, and slightly disturbed sleep are all common. A new tooth visible or sharp under the gum is the clearest sign.
Can teething cause a fever or diarrhoea?
Teething is unlikely to cause a high fever (37.8°C or above), diarrhoea, vomiting, or a heavy nasal discharge. These are more likely to be signs of illness — contact your GP or NHS 111 if you're unsure, especially in younger babies.
Are teething necklaces or gels safe?
Amber teething necklaces are a choking and strangulation risk and are not recommended. Teething gels containing benzocaine are not recommended for babies. Speak to your pharmacist or GP about suitable pain relief if baby is clearly uncomfortable.
What helps with teething pain at night?
A cool (never frozen) teething ring, gentle gum rubbing with a clean finger, and a damp muslin to chew are all worth trying. Keep the chin dry to protect the skin. If baby is clearly uncomfortable, ask your pharmacist or GP about suitable pain relief.
