Tongue-Tie or Lip-Tie or Other Causes of Breastfeeding Difficulties
How Can I Tell If It’s Really a Tongue-Tie or Lip-Tie—or Something Else?
Breastfeeding can be a beautiful and rewarding experience, but it’s not always easy. Many mothers face challenges and wonder if issues like a tongue-tie or lip-tie could be the cause of their baby’s feeding difficulties. A proper latch is key for effective milk transfer and comfort for both mum and baby, but when things aren’t going smoothly, it’s natural to question why. Understanding the possible causes of breastfeeding difficulties can help you feel more confident and supported. In this article, our Brisbane Paediatric Dentist will talk about how to tell if a tongue-tie or lip-tie is the problem — or if something else might be affecting feeding.
What Are Tongue-Tie and Lip-Tie?
Tongue-Tie (Ankyloglossia)
Tongue-tie happens when the thin piece of tissue under the tongue (the lingual frenulum) is too short or tight, making it harder for the tongue to move properly. This can affect a baby’s ability to latch and breastfeed effectively, which may cause discomfort for both the baby and the mother. If untreated, tongue-tie can sometimes lead to speech difficulties and other oral issues later on.
Lip-Tie
Lip-tie occurs when the piece of tissue connecting the upper lip to the gum (the labial frenulum) is too tight or thick, restricting lip movement. This may make it hard for a baby to get a good seal while breastfeeding, leading to poor milk transfer and discomfort for the mum. In some cases, it may also affect the spacing of the front teeth and cause oral hygiene issues as the child grows.
A Tongue-Tie, Lip-Tie or Other Causes of Breastfeeding Difficulties?
Look at the Whole Picture First
Before assuming it’s a tongue-tie or lip-tie, check these basic factors:
Baby’s Latch: Is your baby’s mouth opening wide enough to take in enough of the breast? A shallow latch can look like a tongue-tie problem even when it’s not.
Baby’s Suck: Does your baby make strong, regular sucking movements Babies with a tight tongue might struggle to create a proper seal or have trouble lifting or extending their tongue.
Baby’s General Health: Are there other issues like low muscle tone, oral or facial differences, or health problems that might affect feeding? Prematurity or other medical conditions can also cause feeding issues.
Mum’s Health and Milk Supply
- Are you making enough milk?
- Is your nipple shape making it difficult for your baby to latch?
- Are you feeling stressed, exhausted, or unwell? Stress and health issues may affect the milk supply.
Feeding Environment: Is the room quiet and calm? Too much noise or distraction might make feeding harder for the baby.

Signs That Point to a Tongue-Tie or Lip-Tie
If you’ve checked the basics and are still seeing problems, a tongue or lip tie might be the issue. Here’s what to look for:
Physical Signs
- A short, thick piece of tissue under the tongue (lingual frenulum).
- A tight, thick band under the top lip (labial frenulum).
- The frenulum might attach close to the tip of the tongue or deep into the upper gum.
Feeding Troubles
- Difficulty latching or staying latched.
- Clicking or smacking sounds while nursing.
- Feeding sessions that last too long or happen very often.
- Poor weight gain despite regular feeding.
- Signs that your baby isn’t draining the breast properly.
- Mum experiencing sore, cracked, or bleeding nipples.
- Recurring mastitis (blocked ducts or infections).
Lip-Tie Specific Signs
- A noticeable gap between the top front teeth may suggest a lip-tie, but it might also result from natural spacing or genetics.
- A tight upper lip that doesn’t flange outward may indicate a lip-tie, especially if it restricts suction during feeding.
- Baby’s upper lip appearing stuck to the gum during feeding may suggest a lip-tie, but it can also happen due to poor latch positioning.
Rule Out Other Causes
Not all breastfeeding problems are caused by tongue-tie or lip-tie. Sometimes, the issue is something else entirely:
Poor Latch or Positioning
Even if your baby’s tongue and lips are fine, a poor latch can cause similar problems. Try different breastfeeding positions or consult a lactation consultant for help.
Milk Supply Issues
Too much milk (overactive letdown) can overwhelm your baby.
Too little milk can make it hard for your baby to feed properly.
Medical Conditions
Thrush, infections, or oral pain in mum or baby can make feeding uncomfortable.
Neurological Problems
Low muscle tone or issues with your baby’s suck-swallow-breathe coordination can make feeding harder. Premature babies often struggle with this.
Mum’s Medications
Some medications can reduce milk supply or make your baby sleepy or fussy while feeding.
When to Get Help
If you’re struggling with breastfeeding and suspect a tongue-tie or lip-tie, it’s time to reach out for help:
Lactation Consultant
A lactation consultant can help with latch issues, positioning, and milk supply. They often notice signs of a tongue or lip tie early on.
Paediatric Dentist or ENT Specialist
Our Brisbane kids dentist can examine the frenulum closely. If there’s a true tongue-tie or lip-tie, they can discuss treatment options with you.
Speech Pathologist
A speech pathologist can assess your baby’s mouth coordination and swallowing skills. They can help if feeding issues are linked to oral motor development.
Tools Specialists Might Use
Specialists use specific tools and systems to diagnose tongue-tie and lip-tie accurately:
Hazelbaker (HATLFF)
The Hazelbaker Assessment Tool for Lingual Frenulum Function (HATLFF) is a scoring system used to evaluate how the tongue looks and moves. It assesses factors like tongue lift, extension, and side-to-side movement. The tool also checks how well the baby’s tongue functions during feeding, such as creating a proper seal and sustaining suction. A low score may suggest that a tongue-tie is affecting the baby’s ability to breastfeed effectively.
Coryllos Classification
The Coryllos Classification system categorises tongue-ties based on where the frenulum attaches under the tongue. Type 1 and Type 2 ties are located at the tip or front of the tongue, which are easier to identify and treat. Type 3 and Type 4 ties are further back, closer to the base of the tongue, and may be less visible but more restrictive. This system helps specialists determine the severity of the tongue-tie and whether treatment is needed.
Kotlow Classification
The Kotlow Classification grades lip-ties based on how far the tissue extends under the upper lip. A higher grade indicates a more restrictive lip-tie, which can make it harder for a baby to latch properly and create an effective seal. This system helps specialists decide if the lip-tie is severe enough to affect feeding and if a procedure is necessary. Accurate grading allows for more targeted and effective treatment recommendations.
Treatment Options
If a tongue or lip tie is confirmed, there are different treatment options depending on the severity:
Non-Surgical Approaches
If a tongue-tie or lip-tie is mild, non-surgical treatments are often enough to improve feeding. A lactation consultant can help adjust breastfeeding positions and improve your baby’s latch, which can make feeding more comfortable and effective. Oral exercises, like gently stretching the tongue or massaging the upper lip, can also help improve movement and flexibility over time. These non-invasive approaches can often resolve minor feeding issues without needing a procedure.
Surgical Options
Frenotomy
What It Is: A frenotomy is a quick and simple procedure where the tight tissue under the tongue or lip (the frenulum) is snipped or clipped. It’s usually done on babies and young infants because the tissue is thin and has very few nerve endings.
Healing Time: Healing is usually quick, with minimal discomfort for the baby. Most babies can breastfeed immediately after the procedure.
When It’s Used: Frenotomy is typically used for minor or simple tongue-ties or lip-ties that are causing feeding difficulties but are not severely restrictive.
Frenectomy
What’s Involved: A frenectomy involves the complete removal of the tight band of tissue (frenulum) under the tongue or lip.
How It’s Done: It’s usually a quick procedure performed with scissors, a scalpel, or a laser. The laser option may result in less bleeding and faster healing.
When It’s Used: A frenectomy is recommended for more significant or thicker tongue-ties or lip-ties that are clearly affecting feeding, speech development, or dental health.
Conclusion
Breastfeeding isn’t always easy, and it’s normal to face some bumps along the way. Figuring out if your baby has a tongue-tie, lip-tie, or something else going on is an important step toward making feeding easier and more comfortable. If you’ve already tried the basics and still have questions, don’t hesitate to reach out to a lactation consultant, pediatric dentist, or speech pathologist—they’re there to help you and your baby. Every breastfeeding journey is different, and with the right support, you’ll find what works best for both of you.
