Epstein Pearls

Overview

Epstein pearls are very small, whitish or yellowish bumps that can appear inside a newborn baby's mouth. They usually show up on the roof of the mouth (the palate) or along the gums, often in a line. They are tiny collections of keratin — a protein that makes up skin, hair and nails — that got trapped under the surface while the baby was growing in the womb. They are not teeth, not an infection, and not a sign that anything is wrong. They are harmless and they go away on their own, usually within a few weeks to a couple of months.

Yes, very common. They are seen in a large share of newborn babies, though some studies put the number lower or higher depending on how closely babies are checked. Many parents never notice them, and they are often found during a routine newborn check.

Epstein pearls are only seen in newborns and young babies. They appear in babies of all backgrounds and are not linked to sex, feeding method, birth weight or anything the parent did or did not do during pregnancy. They are not found in older children or adults — white patches in an older child's or adult's mouth should be checked by a doctor or dentist.

Symptoms

Common symptoms

• One or more tiny white or creamy-yellow bumps, usually 1 to 3 millimetres across
• Bumps often sit in a line along the roof of the mouth, or on the gum ridge
• The bumps are firm and do not rub off or wipe away
• The skin around them looks normal — not red, swollen or sore
• The baby feeds, sleeps and behaves normally, with no signs of discomfort

Symptoms in children

• Epstein pearls are a newborn finding — they are not expected in older babies or children
• If white patches or bumps appear in an older child's mouth, they may be something else (such as thrush or a mouth ulcer), so it is worth having a doctor or dentist look at them

Symptoms in older adults

• Epstein pearls do not happen in adults
• White patches or lumps in an adult's mouth have many possible causes and should be checked by a dentist or doctor rather than assumed to be harmless

Causes

Main causes

• During normal development in the womb, small amounts of keratin (a tough protein found in skin and hair) get trapped in the lining of the mouth
• The trapped material forms tiny cysts just under the surface, which we see as white bumps after birth
• As the mouth lining renews itself, the cysts come to the surface and disappear on their own

Risk factors

• Being a newborn is the only real factor — this is a normal part of development
• Nothing the parent did or did not do during pregnancy causes Epstein pearls
• They are not caused by feeding, hygiene, teething, or any illness, and they are not contagious

When to see a doctor

See a doctor urgently if:

• Your baby is not feeding well, is very sleepy, or seems unwell in any way
• The bumps become red, sore-looking, bleed, or fill with pus
• Your baby has a fever — especially if they are under 3 months old, seek advice the same day
• You notice fewer wet nappies, a dry mouth, or other signs of dehydration

Book a routine appointment if:

• You are not sure whether the bumps are Epstein pearls or something else
• The bumps are still there after about 3 months
• You notice new white patches that look like milk curd and do not wipe off easily (this can be a sign of oral thrush)
• You notice a tooth-like hard white lump at birth (some babies are born with early teeth, called natal teeth, which a clinician should check)

Diagnosis

A doctor, midwife, nurse or health visitor can usually tell what the bumps are just by looking in your baby's mouth. No special tests are needed. They will check that the bumps are in the typical places, that the surrounding skin looks healthy, and that your baby is feeding and behaving normally.

Tests that may be done

• Usually none — the diagnosis is made by looking
• A general newborn examination, if one has not already been done
• Weight and feeding checks if there are any worries about feeding
• Rarely, a referral to a specialist if the appearance is unusual or the bumps do not go away

What to expect at your appointment

The check is quick and painless. Your clinician will gently look inside your baby's mouth, possibly with a small light, and ask how feeding is going. You may be told that nothing needs to be done and that the bumps will fade. If you are asked to come back for a review, it is usually just to confirm the bumps have cleared.

Treatment

No treatment is needed. Epstein pearls clear up on their own as the lining of the mouth renews itself, usually within a few weeks and almost always within a few months. The most important thing is to leave them alone — popping, squeezing or scrubbing them can hurt your baby and let germs in.

Self-care at home

• Leave the bumps alone — do not squeeze, pop, pick at or scrub them
• Keep cleaning your baby's mouth gently as usual, for example wiping the gums with a soft clean cloth
• Continue normal feeding — breast or bottle — and watch that your baby is feeding and gaining weight well
• Keep up usual nappy counts as a simple check that your baby is getting enough milk
• Take a photo every week or so if you want to track whether the bumps are fading

Medical treatments

There is no medical treatment for Epstein pearls, and none is needed. Because they are harmless and heal by themselves, clinicians do not prescribe creams, mouthwashes or medicines for them. If a clinician thinks the white patches are something else — such as oral thrush — they will explain the options and discuss any suitable treatment with you.

When is surgery considered?

Surgery is never needed for Epstein pearls. They are not removed, cut or drained. Any suggestion of surgery for white bumps in a newborn's mouth would be unusual and worth discussing carefully with your child's doctor.

Living with this condition

Life carries on as normal. Feed your baby as usual, keep up gentle mouth care, and enjoy the early weeks. You do not need to check the bumps constantly — a glance now and then is plenty. Many parents find the bumps have quietly disappeared at a routine check without anyone noticing exactly when.

Lifestyle tips

• Keep up your usual feeding routine and skin-to-skin contact
• Wash your hands before touching your baby's mouth or anything that goes into it
• Sterilise bottles and teats as you normally would if you are bottle feeding
• Attend your baby's routine newborn and postnatal appointments
• Ask your midwife or health visitor anything that is on your mind — no question is too small

Diet and exercise

There is nothing to change about feeding. Breast milk or formula is all your baby needs. Epstein pearls do not affect feeding, and babies with them feed just as well as other babies. For you, eating well, drinking enough and resting when you can will help your own recovery. Gentle movement, like short walks with the pram, is good for your mood and energy once you feel ready.

Mental health and emotional wellbeing

It is very normal to feel worried when you spot something new in your newborn's mouth. Many parents describe a rush of 'what if' thoughts, especially in the exhausting early weeks. Remember that Epstein pearls are a normal, harmless finding, and your worry is a sign of how much you care — not a sign that something is wrong. If anxious thoughts are stopping you sleeping, eating or enjoying your baby, please tell your midwife, health visitor or doctor. Postnatal anxiety and low mood are common and treatable, and support is available. If you ever have thoughts of harming yourself or your baby, contact your local emergency number or a crisis line straight away.

Prevention

No, Epstein pearls cannot be prevented, and there is nothing you could have done differently. They happen before birth as part of normal development and are not caused by diet, hygiene, stress, medicines or anything else during pregnancy.

Screening programmes

No screening is needed. Epstein pearls are usually spotted during the routine newborn physical examination or noticed by parents, and they do not need any follow-up tests once identified.

Complications

If left untreated

• There are no complications from leaving Epstein pearls alone — they simply fade
• The main risk comes from trying to remove them: squeezing or picking can break the skin and allow infection
• Rarely, an injured spot could become sore and make feeding uncomfortable for a short time
• If white patches are actually oral thrush and are not recognised, feeding may become uncomfortable — which is why a check is useful if you are unsure

Long-term outlook

Excellent. Epstein pearls are harmless, painless and clear up completely on their own, usually within weeks and almost always within a few months. They leave no marks, cause no lasting problems, and do not affect teeth or speech. If you have any doubt at all, ask your midwife, health visitor or doctor to take a look — a quick check is all it takes to feel reassured.
