The Hidden Impact of a Lip Tie

A lip tie happens when the tissue that connects the upper lip to the gums (called the labial frenulum) is too thick, too short, or too tight. While some lip ties are mild and cause no problems, others can significantly impact health, development, and daily function.

How a Lip Tie Can Affect Infants

In babies, a restrictive lip tie can make feeding difficult. When the upper lip can’t move freely, the baby may struggle to create a proper seal while nursing or bottle-feeding. This can lead to:

• Poor latch during breastfeeding

• Clicking or popping sounds while feeding

• Swallowing air, which may cause gas, fussiness, or reflux-like symptoms

• Inadequate weight gain

For parents, this often means longer, more frustrating feeding sessions and discomfort for both mom and baby.

Speech and Oral Development Concerns

As a child grows, an untreated lip tie can contribute to:

• Difficulty forming certain speech sounds

• Oral motor challenges, such as trouble with lip closure

• Delayed transition to solid foods or picky eating

• Mouth breathing habits that affect jaw and facial growth

Dental and Orthodontic Issues

Dentists often notice lip ties because the tight tissue can pull on the gums and affect dental development. A significant lip tie may cause:

• A gap between the front teeth (called a diastema)

• Increased risk of tooth decay if the lip tie restricts normal lip movement needed for cleaning food away

• Gum recession over time

What Can Be Done?

The good news is that lip ties can be evaluated and treated. An evaluation typically involves:

• A thorough functional exam by a myofunctional therapist

• Observing feeding, speech, and oral movements

• Collaborating with other providers (such as dentists, lactation consultants or ENTs) when needed

Treatment may include myofunctional therapy, feeding therapy, or—when appropriate—a minor procedure to release the tie. The key is early recognition and individualized care.

A lip tie isn’t always a problem, but when it is, it can have a ripple effect on feeding, speech, and dental health. If you suspect that you or your child may have a lip tie, it’s worth seeking a professional evaluation to understand the best path forward.
