A lip tie, or maxillary labial frenulum restriction, occurs when the band of tissue connecting the upper lip to the gum line is too short or thick, limiting the lip’s mobility. A restricted frenulum can interfere with the complex coordination required by the lips, tongue, and jaw for successful eating. This restriction can affect a child’s ability to manage different textures and efficiently consume a balanced diet.
The Physical Mechanics of Lip Tie and Solid Feeding
The process of eating solid foods requires a coordinated action from the entire oral structure, and the upper lip plays a distinct role that is impaired by restriction. A tight labial frenulum physically limits the necessary upward and outward movement of the upper lip, which is necessary for achieving a proper lip seal. This seal is necessary to contain liquids and purees inside the mouth, preventing them from leaking out. Limited mobility also makes it harder for the child to wrap their lips around food when taking a bite or sipping from a cup.
The inability of the upper lip to move freely also directly impacts how a child manages food placed on a spoon. Successfully clearing a utensil requires the upper lip to sweep the food off. When the frenulum is too restrictive, the child cannot effectively “clear” the spoon, leading to excessive food loss and messiness during mealtimes.
The lips are responsible for manipulating or gathering food that has migrated into the upper sulcus (the space between the gums and the lip). An unrestricted upper lip contributes to proper chewing and swallowing mechanics by helping to form a cohesive food mass, known as a bolus.
When the lip is restricted, the child may struggle to keep the food positioned correctly for chewing and swallowing safely. Difficulty forming the bolus and keeping food centralized increases the risk of the child pushing food out of the mouth or having it pocketed in the cheeks. This struggle to manage food efficiently can make mealtimes frustrating.
Recognizing Feeding Difficulties in Infants and Toddlers
The mechanical difficulties caused by a lip tie manifest as several observable symptoms when infants and toddlers transition to solids. One common sign is excessive messiness or drooling of food, indicating an inability to maintain the necessary lip seal during eating. This trouble keeping food and liquids inside the mouth is a direct consequence of limited upper lip mobility.
Parents may also notice food avoidance or a strong preference for soft, pureed, or mashed foods over those with more substantial textures. This preference occurs because the child instinctively avoids foods that require the complex lip and oral movements they struggle to perform. Children may stick to softer foods simply because they are easier to manage, which can negatively affect growth and overall health.
If the child attempts to eat textured foods, they may exhibit habitual gagging, coughing, or choking more often than expected. Another indicator is food pocketing, where food gets stuck under the upper lip or accumulates in the cheek area because the child cannot effectively retrieve it. This difficulty in moving food around the mouth can lead to prolonged mealtimes as the child tires easily from the effort required.
This constant struggle can result in frustration during meals and may delay the child’s readiness for solid foods. If a lip tie is not addressed early, these symptoms can continue into school age.
Treatment Options for Lip Ties
The standard intervention for a restricted labial frenulum is a frenotomy or frenectomy. This procedure involves the release of the restrictive tissue to restore full mobility to the upper lip. The frenotomy is typically quick and can be performed using specialized instruments like a sterilized surgical scissor or a CO2 laser.
Utilizing a laser offers benefits such as minimal bleeding, reduced risk of infection, and quicker healing times. The procedure is often performed without general anesthesia, especially in younger children, and takes only a few minutes. Immediately following the release, parents are instructed to perform specific stretches to the upper lip to prevent the released tissue from reattaching as it heals.
While the frenectomy addresses the physical restriction, some children may still require follow-up feeding therapy to retrain the oral muscles that have compensated for the tie. A successful procedure can lead to an improved quality of life and allows for a more successful transition to solid foods. Early diagnosis and intervention can help prevent the development of long-term issues and lead to better overall oral function.
