Tongue-tie release (Frenotomy (frenulotomy) for ankyloglossia)

What is a tongue-tie release?

Tongue-tie (ankyloglossia) is when the strip of tissue connecting the underside of the tongue to the floor of the mouth (the frenulum) is short or tight, which can limit how far the tongue moves. A tongue-tie release, or frenotomy, divides this band so the tongue can move more freely.

In young babies the procedure is usually very quick and done without anaesthetic: the practitioner steadies the tongue and divides the band with sterile blunt-ended scissors. There is normally little or no bleeding, and the baby can feed straight afterwards.

The procedure is offered mainly to help with breastfeeding when a tongue-tie is genuinely getting in the way — for example causing problems with latching, ongoing nipple pain, or poor weight gain. Many tongue-ties cause no problems at all and do not need treating. There is little evidence that division helps with bottle feeding, and it is not done simply to prevent possible future speech problems.

Types, options & approaches

There may be different ways to do this. The right approach depends on the clinical question and your circumstances.

Options at a glance

These are the main approaches described in this guide. The right option depends on the diagnosis, your goals and what your clinician thinks is safe.

Preparing for your procedure

• Have your baby assessed by a trained tongue-tie practitioner or feeding specialist, who will check whether the tie is really the cause of the feeding problem.
• Ask for skilled breastfeeding support first, as positioning and attachment changes sometimes solve the problem without a procedure.
• Bring your baby's red book and feeding history, including any weight concerns.
• Dress your baby in clothing that is easy to unwrap and re-dress.
• Plan to feed your baby shortly before and straight after the procedure.
• For an older child having division under general anaesthetic, follow the fasting instructions you are given.

What happens

For a young baby, the practitioner checks the mouth and confirms the tongue-tie is likely to be affecting feeding. Your baby is gently wrapped to keep still, and the tongue is lifted. The tight band is divided with sterile blunt-ended, round-tipped scissors. The whole thing takes only seconds.

There is usually only a little bleeding, which settles quickly, often as soon as the baby feeds. The practitioner checks the bleeding has stopped before you leave, and you are usually encouraged to feed your baby in the clinic. A small diamond-shaped raw area is left under the tongue, which heals on its own.

For an older child, where the frenulum is thicker and the child cannot stay still, the same idea is carried out as a brief operation under general anaesthetic, sometimes with a dissolvable stitch.

Is this procedure right for me?

A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.

Before you decide

Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.

Comfort, sedation or contrast choices

If local anaesthetic, sedation, contrast or pain relief is used, ask what is planned, why, and what it means afterwards.

The biggest uncertainty is whether the tongue-tie is truly the cause of the feeding difficulty, because feeding problems often have several causes. The commonest complication is minor bleeding, and the main downside is that some ties re-form and need dividing again, which is more common with posterior ties. Ask the practitioner how they confirmed the tongue-tie is the problem, what feeding support comes with the procedure, and what to do if bleeding restarts at home.

Published figures to discuss

Division of tongue-tie in young babies is regarded as a low-risk procedure. NICE concluded the evidence is adequate to support its use for breastfeeding difficulty, provided proper consent, audit and governance are in place. The commonest complication is minor bleeding. The main uncertainty is not safety but whether division will actually improve feeding, which depends on correct selection and good feeding support.

These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.

What happens afterwards

There is usually no real recovery period for a young baby — feeding can resume immediately and the wound heals on its own over one to two weeks. For an older child having a general anaesthetic, recovery follows the usual day-case pattern.

• A small diamond-shaped white or yellow area under the tongue while it heals
• A little blood-tinged saliva at first
• Some babies feed better quickly; others take days to weeks
• Brief fussiness or mild discomfort
• No need for routine pain relief in most young babies

Aftercare

• Feed your baby as normal and as often as they want; feeding aids healing and comfort.
• Continue working with a breastfeeding or feeding specialist if latch or pain has not fully settled.
• Expect a white or yellow patch under the tongue — this is normal and does not need treatment.
• Do any gentle tongue or mouth movements only if your team has specifically advised them.
• Watch for bleeding restarting on the day of the procedure and apply gentle pressure if it does.
• Contact your tongue-tie service if feeding does not improve or you have concerns.

• A plan for ongoing breastfeeding or feeding support
• The tongue-tie service's contact number
• Knowing what the healing patch looks like (diamond-shaped, white/yellow)
• A feed planned for straight after the procedure
• Awareness of the warning signs for bleeding
• A follow-up feeding review arranged if needed

Scars and how they heal

Inside the mouth the small wound usually heals without a visible scar. A white or yellow diamond-shaped patch under the tongue during healing is expected and fades over one to two weeks.

⚠ Get urgent help if…

• Bleeding from under the tongue that does not stop with gentle pressure
• Bleeding that soaks through and keeps refilling the mouth — seek urgent help
• Your baby refusing to feed for a prolonged period
• Signs of a poorly baby: fewer wet nappies, drowsiness, or a high temperature
• Increasing redness, swelling or pus under the tongue
• Any difficulty breathing — call emergency services

Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.

General guidance — it doesn't replace the specific advice your surgeon gives you.

Results & realistic expectations

When a tongue-tie was genuinely limiting feeding, division can make breastfeeding more comfortable and effective, and may reduce nipple pain. Some families notice a difference at the next feed; for others it takes days or weeks and depends on continued feeding support.

A tongue-tie release cannot guarantee that feeding will become easy, because latch, positioning, milk supply and the baby's general health all play a part. It is best thought of as one part of feeding support rather than a complete fix, and there is no reliable evidence it prevents future speech difficulties.

Once divided, an anterior tongue-tie usually stays divided. Some ties, particularly deeper posterior ones, can re-form and occasionally need a second procedure. As a child grows, the tongue and mouth keep developing normally, and any later concerns about speech should be assessed in their own right by a speech and language therapist.

Related tests, treatments or support

Tongue-tie division is most effective alongside skilled breastfeeding support, which addresses positioning and attachment. Some families also see a lactation consultant. In older children, assessment by a speech and language therapist may be more useful than division if the main concern is speech.

Follow-up & long-term care

Many services offer a feeding review after the procedure to check that latch and comfort are improving. If problems continue, ongoing support from a feeding specialist or lactation consultant is usually more helpful than repeating the procedure straight away. Your team will advise whether a repeat division is appropriate.

• Continued breastfeeding support until feeding is comfortable and effective
• A speech and language assessment later only if there are genuine speech concerns
• Review if the tie appears to re-form and feeding difficulties return

Repeat, follow-on and what comes next

• Some ties, particularly posterior ones, re-form and a small number of babies need a second division.
• Repeating the procedure is not always the answer if feeding problems persist — feeding support is often more useful.
• Division is one part of feeding care, not a guaranteed one-off fix.

Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.

What good aftercare looks like

• Feeding observed and supported in the clinic, with the baby fed before leaving.
• Clear written advice on normal healing and when bleeding needs attention.
• A named contact for feeding worries and a follow-up feeding review where appropriate.
• Honest discussion that improvement can take time and may need continued support.
• Onward referral to speech and language therapy if speech concerns arise later.

What affects the cost

Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:

• The practitioner's fee for assessment and the procedure
• Whether feeding or lactation support is included
• Whether it is done in clinic (young baby) or as a day-case operation under general anaesthetic (older child)
• Any follow-up feeding reviews
• Whether a repeat procedure is included if the tie re-forms
• Facility or hospital fees if a general anaesthetic is needed

• The practitioner's fee for assessment and division
• Whether breastfeeding/feeding support is included
• Whether follow-up feeding reviews are included
• What happens, and what it costs, if the tie re-forms and needs repeating
• For older children, the anaesthetic and facility fees
• The cancellation policy

On the NHS? Tongue-tie division for breastfeeding problems is available on the NHS through tongue-tie services, usually after a feeding assessment; some families use private practitioners for speed.

You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.

Consent traps and marketing red flags

These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.

Choosing a specialist safely

• Check the surgeon is on the GMC Specialist Register for this area.
• Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
• You're entitled to time to consider and to have your questions answered before you agree — the surgeon who looks after you should explain it, not a salesperson.
• Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
• You're entitled to your total cost in writing — including any follow-up — before you decide.
