Tongue tie assessment & division for babies (frenulotomy)

We are able to assess and treat babies between 3 days and 16 weeks old for frenulotomy. An appointment includes a feeding assessment of your baby (breast or bottle) followed by an oral assessment, determining your baby’s tongue function and movement. Frenulotomy (division) is then offered as necessary.

You will be asked to send us a couple of photographs/videos of your baby’s mouth and a completed questionnaire about your experiences so far, prior to the appointment taking place. Full details will be given when booking an appointment.

What is Tongue Tie?

Tongue tie is defined as ‘ a congenital anomaly characterised by an abnormally short lingual frenulum, which restricts the mobility of the tongue’ (NICE 2005)

This means that some babies are born with a tighter than usual piece of skin between the underside of their tongue and the bottom of their mouth. As the lingual frenulum is shorter than usual, the tongue movement is restricted. it can run in families, occurs more in boys than in girls and when babies are born prematurely.

How do I know if my baby has it?

Sometimes it is possible to see that the lingual frenulum is tight and appears to restrict the baby’s tongue movement. Other times it is not visually obvious and the mother may be experiencing difficulties and/or pain with feeding the baby.

Occasionally soon after birth, a midwife or doctor examining your baby may have suggested to you that your baby has tongue tie. However until your baby has been feeding for a few days, it is not possible to know if it is significant or not.

How can my baby’s feeding be affected?

Tongue tie can affect both breast and bottle feeding. The effects are often more obvious with breastfeeding. Due to the tongue movement being restricted, often the baby finds it difficult to ‘latch’ onto the breast and/or cannot maintain the ‘latch’ on the breast – the baby slips off frequently causing nipple pain/damage, breastfeeding takes a long time and occurs frequently. Baby may appear restless, unsettled and hungry. Eventually weight gain could be affected.

If bottle feeding, the baby may also take a long period of time to feed, or drink only small amounts or dribble lots of milk when feeding. (It is important to note however that these issues may NOT be caused by tongue tie and therefore full consultation needs to be undertaken. It is also possible that performing frenulotomy affords no change or improvement to feeding)

How is it treated?

If your baby is diagnosed with tongue tie which is affecting their feeding, then the usual treatment is for the tight lingual frenulum under the tongue to be separated or divided releasing the tongue to be able to move normally. This is called frenulotomy or tongue tie division.

Frenulotomy is the medical name given to separating, dividing or cutting the lingual frenulum under the tongue. It is a simple procedure which can be performed safely on young babies without anaesthetic.

What can I expect during a tongue tie appointment?

Tongue tie appointments take 60 minutes and will usually be facilitated by two practitioners. It includes an observation and assessment of your baby’s feeding (breast or bottle) and an assessment of your baby’s mouth for tongue function and the appearance of the lingual frenulum. These results will then be discussed with you.

Should frenulotomy be indicated, this will be explained fully to you and should you wish to proceed, asked to sign a consent form.

Immediately after the frenulotomy procedure, the baby will need to be fed with either breast or bottle. Parents will be advised to leave the clinic only when any bleeding has stopped and the baby is calm. Parent(s) can be present throughout the whole appointment.

What follow up care will there be? 

All follow up care is free of charge. Parents will receive a follow up phone call to ask about wound healing, how feeding is going and any other questions they wish to discuss. Should parents have any concerns following frenulotomy, they are advised to call the Clinic and a practitioner will contact them as soon as possible. Parents can make a face to face follow up appointment if they desire (no charge).


16 weeks or older Tongue Tie Assessments

Stonegate Clinic offers a tongue tie assessment service for babies who are over 16 weeks old. If you are concerned that your baby has a tongue tie and would like a full assessment, we can offer this service.

The assessment involves you and your baby attending for a face to face appointment. During this appointment you will be asked about the feeding experience with your baby and your baby’s mouth would be examined. Although the tongue tie (if diagnosed) may not be treated by frenulotomy at the clinic, the results of the examination will be shared and discussed with you. A letter summarizing the details of the assessment findings will then be emailed to you.
