Baby Frenulum Between Front Teeth: When to Worry About Lip Ties

The labial frenulum is the thin band of tissue connecting your baby’s upper lip to their gums. If it extends between the front teeth, it is often referred to as a lip tie. In most cases, this is a normal anatomical variation that resolves on its own as the child grows, though it can occasionally affect breastfeeding or cause a gap between teeth.

Understanding the Labial Frenulum

Everyone has a superior labial frenulum, which is more prominent in infants and young children. When this tissue is particularly thick or attaches very low near the gum line, it may be classified as a lip tie. While this can sometimes create a gap between the front teeth (a clinical condition called a diastema), it is rarely a cause for immediate medical concern. Clinical note: A persistent, thick frenulum attachment is a common, though not exclusive, cause of a midline diastema in primary dentition.

Breastfeeding and Lip Ties

If your baby has a lip tie, you may worry about breastfeeding. According to a position statement issued by the Australian Collaboration for Infant Oral Research (ACIOR) in the journal Australasian Dental Practice, a surgical procedure is not always necessary for breastfeeding an infant with a lip tie. Many families find success by working with a lactation consultant or adjusting breastfeeding techniques.

If feeding challenges persist, a minor procedure called a frenotomy can be used to correct it. The procedure involves removing the part of the labial frenulum extending beyond the normal range, often using a dental laser. Your baby will likely be able to breastfeed immediately, as the release allows the mouth to open wider and attach more easily. Few babies require medication after the procedure. To ensure the area heals properly and the tissue does not reattach, you should perform prescribed stretches and massages several times a day for several weeks.

Managing Frenulum Injuries

Toddlers are prone to falls, and because the labial frenulum is located in a high-impact area, it is frequently bruised or torn during minor accidents. Red flag: While minor tears from falls are common, a frenulum tear in a non-mobile infant or a child without a history of a recent fall should be evaluated by a healthcare professional to rule out non-accidental trauma. If your child sustains an injury to this area, it usually heals on its own. However, if the wound is deep, it may require a checkup with a health professional to ensure it heals correctly.

When to See a Dentist

We recommend scheduling your child’s first dental visit by their first birthday. This allows your dentist to identify any oral disorders, monitor the development of the frenulum, and assess any gaps between teeth. During this visit, your child can become familiar with the dental office and the professionals who work there, which helps build a positive, long-term relationship with oral health care.

Frequently Asked Questions

Does a baby frenulum between front teeth always cause a gap?

No. While a prominent frenulum can contribute to a gap (diastema), it does not guarantee one. This gap might also affect permanent teeth, but many children have prominent tissue without significant spacing.

Is surgery always necessary for a lip tie?

No. Many infants with lip ties breastfeed successfully without intervention. Surgery is generally reserved for cases where the tie significantly hinders feeding.

What happens if the frenulum is torn?

Most minor tears heal on their own without complications. If the wound is deep, it may require a checkup with a health professional to ensure it heals correctly.

Why is the first dental visit important?

A first-year dental visit helps identify any oral development issues early and ensures your child becomes comfortable in the dental environment, setting the stage for a lifetime of good oral health.
