If you’ve noticed your baby having difficulty breastfeeding or your child struggling with certain oral functions, you might have heard the term “lip tie” mentioned by healthcare providers. While it’s a condition that often flies under the radar, understanding what a lip tie is and how it’s diagnosed can help you identify potential issues early and seek appropriate treatment.

What Is a Lip Tie?

A lip tie occurs when the small piece of tissue connecting the upper lip to the upper gums (called the labial frenulum) is too thick, too tight, or extends too far down the gum line. This restrictive tissue can limit the movement of the upper lip, making it difficult for the lip to lift properly. While everyone has a labial frenulum, problems arise when this tissue restricts normal oral function.

In infants, a lip tie can interfere with breastfeeding by preventing the baby from creating a proper seal around the breast. In older children and adults, it can contribute to various dental and speech issues if left untreated.

Common Lip Tie Symptoms

Recognizing lip tie symptoms is crucial for early intervention. The signs can vary depending on age:

In Infants

  • Difficulty latching during breastfeeding
  • Clicking sounds while nursing
  • Poor weight gain or slow growth
  • Excessive gassiness due to swallowing air
  • Frequent breaking of the latch during feeding
  • Inability to hold a pacifier

In Older Children and Adults

  • A gap between the upper front teeth
  • Difficulty cleaning the front teeth, leading to decay
  • Speech difficulties, particularly with certain sounds
  • Gum recession or inflammation
  • Discomfort when moving the upper lip

How Is a Lip Tie Diagnosed?

Lip tie diagnosis is typically straightforward and can be performed by a qualified dental professional like Dr. Priti Dagli, DDS, FICOI, at Plainsboro Dental Services. The diagnostic process involves a simple visual and physical examination.

During the evaluation, the dentist will gently lift your child’s upper lip to observe the frenulum attachment. They’ll assess several factors, including where the tissue connects to the gum line, how thick the tissue is, and whether it restricts lip movement. The dentist may also check for related conditions, such as tongue tie, which often occurs alongside lip ties.

Dr. Dagli will classify the severity of the lip tie, which helps determine the appropriate treatment approach. Classifications typically range from mild to severe based on how much the tissue restricts movement and function.
