Also known as: tight upper lip frenulum, upper lip restriction, restrictive labial frenulum, tight lip tissue, limited upper lip mobility, tethered upper lip

Lip tie is a condition where the band of tissue connecting the upper lip to the gums is unusually tight, thick, or restrictive, limiting how freely the upper lip can lift or flange. In infants, this may show up as trouble latching, clicking during feeds, milk leakage, prolonged nursing or bottle-feeding, or frustration while eating. In older children, it may contribute to irritation where the lip attaches, food trapping, or difficulty lifting the upper lip comfortably during daily activities.

Not every lip tie causes symptoms, but when restriction affects feeding, oral function, or comfort, an evaluation can help determine how significant it is. Some children compensate well, while others develop latch challenges, irritation near the upper lip attachment, or ongoing functional concerns as they grow. Early assessment helps identify whether monitoring, supportive guidance, or treatment such as a frenectomy is the best next step.

Possible Causes of Lip Tie

Lip tie is commonly associated with:

  • Congenitally tight or thick upper lip frenulum – Some children are born with a band of tissue attaching the upper lip to the gums that is shorter, thicker, or tighter than usual, which can limit normal upper lip movement from infancy onward.

  • Restricted upper lip flanging during feeding – Limited upper lip mobility can make it harder for babies to latch well, maintain a seal, or stay comfortable during breast or bottle feeding.

  • Tension or irritation where the lip attaches – When the upper lip cannot lift freely, the attachment area may look tight, blanch, or become irritated, especially during feeding or oral care.

  • Ongoing restriction with daily oral function – As children grow, lip tie may contribute to food trapping, hygiene difficulty, or discomfort when lifting the upper lip for normal oral tasks.

Treatments for Lip Tie

Depending on the cause of lip tie, treatment may include:

  • Frenectomy – A frenectomy gently releases restrictive tissue under the upper lip so the lip can move more freely. When lip tie is affecting feeding, comfort, or oral function, this treatment can improve mobility and reduce restriction.
  • Well-Baby Exams – For infants, an early evaluation can help identify lip tie and determine whether the restriction is affecting latch, feeding, or oral comfort. This gives parents a clearer path forward if treatment is needed.
  • Laser Dentistry – In some cases, soft tissue treatment may be performed with laser technology for precision and comfort. This can be a useful option when restrictive tissue is contributing to feeding or upper lip function concerns.

When to See a Dentist

Consider scheduling an appointment if your child:

  • Has trouble latching, sealing, or staying latched during feeds
  • Seems frustrated, fatigued, or leaks milk during feeding
  • Cannot lift or flange the upper lip well
  • Has ongoing irritation, hygiene, or upper lip mobility concerns
