Lip ties are a common anatomical finding in newborns and infants, but they rarely need treatment. Studies show that while a significant number of babies have some form of lip tie, only a small percentage experience problems that require intervention. Most lip ties cause no symptoms at all and resolve or become less noticeable as the child grows.
What Is a Lip Tie and How Is It Different From a Tongue Tie?
A lip tie is a tight band of tissue called the frenulum that connects the upper lip to the gums. Everyone has this tissue. The question is whether it is unusually short, thick, or tight enough to restrict movement.
A tongue tie, medically known as ankyloglossia, is the same type of tissue but located under the tongue. Both conditions can affect breastfeeding, but they are separate issues. A baby can have one without the other, though they often occur together.
The upper lip frenulum is classified by how it attaches. A normal frenulum attaches high on the gum, well above the teeth. A lip tie attaches lower, sometimes extending between the front teeth or reaching toward the roof of the mouth. The severity of the attachment determines whether it might cause problems.
How Common Are Lip Ties Really?
Research consistently shows that lip ties are common. Studies examining newborns have found that a large percentage of healthy infants have some degree of lip tie. Estimates vary widely depending on how doctors define the condition, but most research suggests that a noticeable lip tie appears in a substantial minority of infants.
What matters more than how many babies have the tissue is how many have symptoms. The vast majority of lip ties are harmless. They do not interfere with feeding, speech, or dental development. Most parents never notice them, and most pediatricians do not flag them during routine exams.
This is an important distinction. A lip tie is a physical finding, not a disease. Having the tissue does not mean something is wrong. Treatment is only considered when the lip tie causes a measurable problem.
What Problems Can a Lip Tie Cause?
When a lip tie does cause issues, the problems usually appear during breastfeeding. A tight upper lip frenulum can prevent a baby from flanging the upper lip outward to create a proper seal around the breast. This can lead to poor latch, clicking sounds during feeding, and inadequate milk transfer.
Mothers may experience significant nipple pain, cracking, or damage from a baby who cannot latch deeply enough. Some babies tire quickly during feeds or gain weight slowly. These are the situations where a lip tie becomes clinically relevant.
Beyond infancy, some dentists and speech therapists have suggested that lip ties can contribute to tooth decay in young children. The theory is that a tight frenulum can trap milk or food against the upper front teeth. This is plausible, but the evidence is not strong. No large studies have confirmed that lip ties independently cause cavities.
Speech problems are sometimes blamed on lip ties. The evidence here is also limited. The upper lip is not heavily involved in most speech sounds. Some clinicians report improvement in certain sounds after release, but research has not established a clear connection between lip ties and speech delays.
Do Lip Ties Affect Older Children or Adults?
In older children, a lip tie can sometimes create a gap between the two upper front teeth. This gap, called a diastema, is common in young children anyway. Many children have a temporary gap that closes on its own as other teeth come in.
When a thick frenulum sits between the front teeth, it can keep the gap from closing naturally. Some dentists recommend releasing the frenulum before or during orthodontic treatment to prevent the teeth from separating again after braces close the gap. This is a common and well-accepted reason for treatment in older children.
In adults, lip ties rarely cause problems. The tissue typically becomes less prominent with age. Adults who have lived with a lip tie without issues generally do not need treatment. There is no evidence that releasing an asymptomatic lip tie in an adult provides any benefit.
How Is a Lip Tie Treated?
Treatment for a lip tie is a simple procedure called a frenectomy or frenotomy. The doctor cuts the tight band of tissue to free the upper lip. The procedure is quick, usually taking only a few minutes.
In infants, the procedure is often done in a pediatrician’s or dentist’s office with local numbing. Some providers use a laser, while others use sterile scissors. Both methods are effective. The choice depends on provider training and preference rather than clear evidence that one is superior.
Bleeding is typically minimal. The baby can nurse immediately afterward, which helps soothe the area and may reduce the chance of the tissue reattaching. Healing is usually rapid.
In older children and adults, the procedure is more involved. The frenulum is thicker and contains more blood vessels. Sutures may be needed. Recovery takes longer, and there is a small risk of scarring or reattachment.
When Is Treatment Actually Necessary?
Treatment is clearly indicated when a lip tie interferes with breastfeeding and conservative measures have failed. If a lactation consultant has helped with positioning and latch, and the baby still cannot feed effectively because of the tight frenulum, release is a reasonable option.
Treatment is also reasonable when a thick frenulum prevents the front teeth from closing a gap during orthodontic treatment. This is a functional issue with a clear goal: keeping the teeth in their corrected position.
Beyond these situations, the evidence for treatment is weak. Releasing a lip tie to prevent future cavities, improve speech, or avoid problems that have not yet appeared is not supported by strong research. Some clinicians recommend these procedures, but the benefits are not well established.
Before any procedure, a thorough feeding assessment is essential. Many breastfeeding problems have multiple causes. A lip tie may be present but not be the actual reason a baby is struggling. Releasing the frenulum when the real issue is something else will not solve the feeding problem.
What Does the Research Say About Outcomes?
Studies on lip tie release in infants with breastfeeding difficulties generally show improvement. Most mothers report better latch and reduced nipple pain after the procedure. However, many of these studies are small, and not all include a comparison group.
Some research suggests that a significant number of babies improve on their own without any intervention. Breastfeeding is a learned skill for both mother and baby. As the baby grows and the mouth develops, feeding often becomes easier regardless of the frenulum.
It is also worth noting that lip tie release is not without risks. The procedure can cause pain, bleeding, and, in rare cases, infection. There is also the possibility of the tissue reattaching during healing, which would require repeat treatment.
Parents should weigh these factors carefully. A procedure with real risks should not be done for a theoretical benefit. When the problem is clear and conservative approaches have failed, treatment makes sense. When the problem is uncertain, watchful waiting is a valid and often better choice.
How Common Are Lip Ties And Do They Need Treatment?
Lip ties are common, but treatment is not. The condition is present in many infants, yet only a fraction of those infants develop feeding problems severe enough to warrant intervention. Most lip ties are harmless findings that require no action at all.
The decision to treat should be based on symptoms, not on the presence of the tissue itself. If a baby is feeding well, gaining weight, and the mother is comfortable, a lip tie does not need treatment regardless of how it looks. If feeding is genuinely impaired and other causes have been ruled out, release is a reasonable option.
Parents who are concerned about a lip tie should seek evaluation from a professional experienced in infant feeding. A lactation consultant, pediatrician, or pediatric dentist can assess whether the frenulum is actually causing the problem. This assessment, not the appearance of the tissue, should guide the decision.
Frequently Asked Questions
Can a lip tie cause colic or reflux in babies?
Some clinicians believe that poor latch from a lip tie can cause a baby to swallow excess air, which may contribute to gas and discomfort. However, no strong research confirms that lip ties directly cause colic or reflux.
At what age should a lip tie be treated?
There is no single correct age. In infants, treatment is considered only when breastfeeding problems are present and other interventions have failed. In older children, treatment is most often done during orthodontic care.
Do lip ties fix themselves as a baby grows?
The frenulum often stretches and becomes less restrictive as the baby grows and the facial structures develop. Many lip ties that seem tight in the newborn period cause no problems by the time the child is a few months old.
Is lip tie surgery painful for a baby?
The procedure is quick and performed with local numbing. Babies may cry during the procedure, but pain is typically brief and well controlled with immediate feeding afterward.
