sudden teething

Overview

Teething is the normal process when a baby's first teeth push through the gums. It usually starts around 6 months of age and can cause soreness, irritability, and extra drooling.

Teething is a normal part of infancy and happens to every child. It is not a disease or a medical condition.

Teething affects babies and toddlers, typically from around 4 months to 3 years old. Some babies have more noticeable symptoms than others.

Symptoms

Common symptoms

• Drooling more than usual
• Swollen or tender gums
• Irritability and fussiness
• Wanting to chew or bite on things
• Waking more at night
• Mild flushed cheeks

Symptoms in children

• Same as common symptoms
• Rubbing the gums, ear, or cheeks
• A slight rise in temperature — but less than 100.4°F (38°C)
• Loss of appetite for solid foods

Symptoms in older adults

• Teething is specific to infants and young children. Older adults who have mouth or gum pain should see a dentist, as this is not teething.

Causes

Main causes

• New teeth moving upward through the jawbone and gums
• The pressure and cutting cause local swelling and tenderness
• The body responds with mild inflammation in the gum tissue

Risk factors

• There are no known risk factors — teething is natural.
• Some babies may feel more discomfort when several teeth come in at once.

When to see a doctor

See a doctor urgently if:

• Your baby has a high fever or is very unwell.
• Your baby cannot be comforted for long periods.
• Your baby refuses to drink and shows signs of dehydration.
• There is swelling in the face or jaw that is getting worse.

Book a routine appointment if:

• Your baby has no teeth by 18 months.
• You are worried about your baby's gums or teeth.
• Your baby's symptoms are causing sleep and feeding problems for more than a few days.

Diagnosis

A doctor or nurse will ask about your baby's symptoms and look inside the mouth for swollen or red gums and emerging teeth. This is usually enough.

Tests that may be done

• No routine tests are needed for teething.
• If there is fever or other concerning symptoms, the doctor may check for ear infection, throat infection, or other common childhood illness.

What to expect at your appointment

The visit is quick and easy. The doctor may gently touch the gums and reassure you that teething is normal. They will also ask about your baby's feeding, nappy output, and overall energy.

Treatment

Treatment for teething focuses on soothing your baby's gums and relieving discomfort. Most cases can be managed at home without any medicines.

Self-care at home

• Gently massage your baby's gums with a clean finger or a damp cloth.
• Offer a clean, cool teething ring — but not frozen, as that can harm gums.
• Let your baby chew on a chilled (not frozen) wet washcloth.
• Wipe away extra drool to prevent a rash on the face and neck.
• Try offering a clean, large teether that is too big to swallow.
• Keep to a normal routine as much as possible.

Medical treatments

If your baby is very uncomfortable, talk to your pharmacist, health visitor, or doctor about age-appropriate pain relief. They may suggest a sugar-free paracetamol or ibuprofen product made for babies if the baby is over a certain age. Avoid numbing gels or teething powders unless a doctor has recommended them.

When is surgery considered?

Teething does not require surgery. In rare cases, a dentist may need to remove a very difficult tooth or treat an overgrown gum bump, but this is uncommon.

Living with this condition

Teething comes and goes in phases. You can help your baby by offering safe things to chew on, wiping their face after drooling, and giving extra cuddles. Some babies sleep more poorly when teething — try a little extra comfort at night.

Lifestyle tips

• Start brushing your baby's teeth twice a day with a tiny smear of fluoride toothpaste as soon as the first tooth appears.
• Use a soft, age-appropriate toothbrush.
• Avoid sugar in bottles or dummies, and never dip a dummy in honey.

Diet and exercise

If your baby is over 6 months and eating solids, offer cool, unsweetened foods such as cucumber sticks or a cold spoon. Avoid sugary snacks or drinks. Playing and moving as usual are fine — teething does not require bed rest.

Mental health and emotional wellbeing

Sleep disruption and fussiness can leave parents feeling exhausted and stressed. It is normal to feel frustrated sometimes. Take turns with your partner or a family member, and speak to your health visitor or GP if you need extra support.

Prevention

Teething cannot be prevented — it is a natural part of growing. But you can reduce discomfort by using safe teethers and keeping your baby's gums clean.

Vaccines

Vaccinations are important for overall health, but there is no vaccine that prevents teething.

Screening programmes

No screening is needed for teething. However, your doctor or dentist may recommend a first dental visit by age 1 to check tooth development.

Complications

If left untreated

• Untreated teething usually has no complications — it resolves itself.
• If severe symptoms are caused by another illness and you do not get medical help, that illness could get worse. Always look for signs like high fever or poor feeding.
• Prolonged cheek or face irritation from drool can cause a skin rash, which is treatable with a gentle barrier cream.

Long-term outlook

Teething is temporary. The discomfort usually eases after the tooth breaks through, and most babies and parents manage well with simple home care. If any concerning symptoms appear, seeking medical advice quickly keeps your child safe and healthy.
