NHS-aligned teething care at 4 months: chilled teething rings (refrigerator, not freezer), gentle gum rubbing with a clean finger, distraction and cuddles, with infant paracetamol from 2 months or ibuprofen from 3 months for the worst nights. Teething gels are not licensed below 5 months.

Teething Remedies for a 4 Month Old Baby: An NHS UK Guide

If you have a 4 month old soaking through a third bib by lunchtime, chewing on their fist with renewed vigour, and waking more often at night, you are likely asking one question: has teething started? It is a common concern for UK parents. While the average first tooth appears around 6 months, a sizeable minority, around 1 in 5 babies, will erupt their first tooth between 4 and 6 months. This, combined with the natural maturation of their salivary glands, can make for a drooly, fussy period. This guide walks you through exactly what the NHS recommends for a 4 month old. We will cover which medicines are licensed for this age, which popular remedies to avoid, and the simple, safe measures that genuinely help. Most babies get through this stage with basic comfort and patience. Let us look at the facts.

Is it really teething at 4 months?

The average UK baby cuts the first tooth around 6 months, but the normal range is broad, from 3 to 14 months. About 1 in 5 babies will show signs of teething between 4 and 6 months. The lower central incisors at the front are usually the first to appear, followed by the upper central incisors.

Typical teething signs at this age include increased drooling (though this is also a developmental milestone at 4 months), chewing on fists, toys, or your fingers, a red and slightly swollen patch on the gum, and mild fussiness, often peaking in the evening. You might notice one flushed cheek, slightly disturbed sleep with an extra waking or two, and even a temporary reduction in milk intake or marginally looser stools.

You need to know what is NOT teething. A true fever over 38C, persistent inconsolable crying, watery diarrhoea (four or more loose stools in 24 hours), vomiting, a rash with fever, refusing all feeds, or unusual lethargy are red flags. These symptoms can indicate an ear infection, urinary tract infection, or other viral illness. If you see these, do not put them down to teeth. Trust your instinct and contact NHS 111 or your GP for advice.

What the NHS recommends at 4 months

The NHS approach to teething at any age is comfort and distraction, not active medication as a first step. At 4 months, mechanical comfort is your safest and most effective tool.

Start with a cool teething ring. Place it in the refrigerator for about 30 minutes; never the freezer, as frozen rings are too hard and can damage gums. Solid silicone or BPA-free plastic rings are best. A clean, cool flannel or muslin cloth, dampened and twisted for your baby to gnaw on, also provides satisfying pressure. Gentle gum rubbing with a clean adult finger, pressed firmly along the inflamed area for 30 seconds, can bring instant relief.

Distraction is powerful. A change of scenery, a song, a baby massage, or a walk in the pram can shift your baby’s focus away from the discomfort. Do not underestimate extra cuddles; physical closeness helps babies regulate their pain response. Finally, manage the drool. Pat your baby’s chin and chest dry frequently and use a barrier cream like Sudocrem or Bepanthen to prevent a drool rash.

Infant paracetamol from 2 months: how it works and how to dose

If your baby is consistently distressed despite comfort measures, infant paracetamol is a safe, NHS-approved next step. Paracetamol (such as Calpol Infant or generic infant suspensions, all 120 mg per 5 ml) is licensed in the UK from 2 months, provided your baby was born after 37 weeks and weighs at least 4 kg.

For a baby aged 2 to 3 months, the dose is 2.5 ml. You can give one dose, and if needed, a second dose 4 to 6 hours later. If distress continues after two doses, contact NHS 111 or your GP. From 3 months onwards, the standard dose is 2.5 ml every 4 to 6 hours, with a maximum of four doses in 24 hours.

Always use the syringe provided in the bottle. Paracetamol dulls pain, helping your baby settle and feed. It takes 30 to 45 minutes to work and lasts about 4 hours. Do not use it for more than 48 hours without medical review. It is not a sleep aid for a baby who is not in pain. The community pharmacist can double-check the dose for you if you are unsure.

Infant ibuprofen from 3 months: when it has a place

Ibuprofen (like Nurofen for Children or Calprofen, 100 mg per 5 ml) is a non-steroidal anti-inflammatory drug licensed for UK infants from 3 months who weigh at least 5 kg. Most 4 month olds meet these criteria.

The dose from 3 to 6 months is 2.5 ml three times a day. Give it with or after a feed to minimise stomach upset. Ibuprofen reduces inflammation as well as pain, so it can be particularly effective for a visibly red, swollen gum. It works within 30 minutes and lasts 6 to 8 hours.

It has a useful role when paracetamol alone is not enough, and your baby is visibly uncomfortable. However, do not give ibuprofen if your baby has chickenpox, is dehydrated (fewer wet nappies, vomiting), has bloody stools, or has asthma that is reactive to NSAIDs. Paracetamol and ibuprofen can be alternated for short periods, but always seek pharmacy advice first and keep a written log to avoid accidental double-dosing.

Teething gels: why they are NOT for 4 month olds in the UK

Popular teething gels are not suitable for your 4 month old. Bonjela Teething Gel and Calgel both contain lidocaine, a local anaesthetic. In the UK, they are licensed only from age 5 months. This age restriction is set by the MHRA due to the small risk of methaemoglobinaemia, a blood disorder, and unpredictable absorption in younger infants.

Anbesol products, which contain benzocaine, are for adult use only and are unsafe for babies. Other saline or chamomile-based gels may be marketed for younger babies, but evidence that they work is very weak.

The simple truth is that at 4 months, you do not need a gel. The safest path is to use a cool teething ring and a clean finger for gum rubbing. If pain relief is needed, use infant paracetamol or ibuprofen as described above. Wait until your baby is at least 5 months old before considering a licensed teething gel, and even then, many health visitors suggest they are unnecessary.

Things to avoid completely at 4 months

Some popular remedies are ineffective and dangerous. Amber teething necklaces are advised against by the NHS and the Royal College of Paediatrics. There is no scientific evidence they release pain-relieving succinic acid. The real risks are choking on loose beads and strangulation, especially during sleep.

Frozen teething rings are too hard and can cause cold burns and gum damage. Always use a fridge-cooled ring, not a freezer one. Adult oral gels like Anbesol or Orajel are too strong for infants. Homeopathic teething powders lack evidence of benefit, and some imported brands have been linked to belladonna toxicity.

Never put honey on a dummy or finger; it poses a risk of infant botulism under 12 months. Do not use alcohol on the gums. Avoid hard food sticks like frozen bagels, which are a choking hazard. At 4 months, your toolkit is simple: a chilled ring, a clean finger, and if necessary, infant paracetamol or ibuprofen.

When to call NHS 111 or your GP

Teething should not make your baby seriously unwell. Call NHS 111 or your GP if your 4 month old has a fever over 38C, persistent inconsolable crying for over two hours, watery diarrhoea more than four times in 24 hours, repeated vomiting, a rash with fever, or is lethargic and hard to wake.

Other red flags include refusing all feeds for more than six hours, having fewer than six wet nappies in a day, a bulging or sunken fontanelle, or a suspected ear infection with fever. You know your baby best. Trust your gut feeling that something is not right.

For routine concerns, contact your health visitor team through your GP surgery. Many hold weekly drop-in clinics. If your baby is over 6 months and has a tooth, remember to register them with an NHS dentist. Dental care is free for under 18s.

Sleep and feeding tips for the teething patch

Teething can disrupt night sleep for a few days. Expect one to three extra wake-ups. Keep the bedtime routine identical. A cool teething ring before bed and a quick gum rub can help. A dose of infant paracetamol 30 minutes before bed is reasonable on the worst nights, but avoid using it routinely as a sleep aid.

For feeding, breastfed babies might bite; a calm, firm “Ouch” and unlatch usually stops this. Bottle-fed babies may chew the teat; try a softer or wider one. Prioritise hydration over volume; aim for six wet nappies a day. This is not the time to start weaning unless your baby is already showing all the developmental readiness signs, which is uncommon at 4 months.

Manage drool rash with frequent bib changes and a barrier cream like Sudocrem.

Looking after the first tooth and beyond

Once that first tooth appears, start brushing twice a day. Use a smear, the size of a grain of rice, of family fluoride toothpaste with at least 1000 ppm fluoride. Use a soft baby toothbrush or a clean muslin wrapped around your finger. Brush in the morning and, most importantly, last thing before bed.

Register your baby with an NHS dentist as soon as the first tooth comes through. Care is free for children. Avoid putting anything sweet in a bedtime bottle to prevent tooth decay. Continue with daily NHS Healthy Start vitamin drops (vitamin D) for breastfed babies and formula-fed babies taking less than 500 ml a day.

Frequently Asked Questions

Can a 4 month old really be teething?

Yes. While the average is 6 months, around 1 in 5 UK babies get their first tooth between 4 and 6 months. Look for a red, swollen gum patch and increased chewing, not just drool.

Is Calpol safe for a 4 month old?

Yes. Infant paracetamol is licensed from 2 months in the UK for babies over 4 kg and born after 37 weeks. From 3 months, the dose is 2.5 ml every 4 to 6 hours, up to four times a day. Use the syringe provided.

Is Bonjela or Calgel safe at 4 months?

No. These lidocaine gels are licensed in the UK only from 5 months due to safety risks in younger babies. Use mechanical comfort and infant painkillers instead until your baby is old enough.

Can I give Nurofen for teething at 4 months?

Yes, if your baby is over 3 months and weighs more than 5 kg. The dose is 2.5 ml three times a day with food. Avoid if your baby has chickenpox, is dehydrated, or has reactive asthma.

Are amber teething necklaces safe?

No. The NHS and UK paediatric experts advise against them due to choking and strangulation hazards. There is no evidence they work. Use a cool teething ring instead.

My baby has a high fever, is it the teeth?

No. Teething does not cause a fever over 38C. A temperature at this level in a 4 month old needs assessment for infection. Phone NHS 111 or your GP.

Should I be cleaning the new tooth right away?

Yes. Start brushing twice daily with a smear of fluoride toothpaste as soon as it appears. Register with an NHS dentist for a free check-up.

How long does this stage last?

Each tooth takes about 3 to 5 days to erupt, with the worst symptoms just before and after it breaks through. Episodes are spaced out, so you will not be teething constantly for years.
