What Is a Tongue Tie?

Tongue tie (the medical term is ankyloglossia) occurs when the lingual frenulum — the thin band of tissue connecting the underside of the tongue to the floor of the mouth — is shorter, thicker, or tighter than usual, restricting the tongue's range of motion. The tongue is a highly mobile, muscular organ, and breastfeeding requires a complex range of tongue movement: lifting, cupping, extending, and applying rhythmic pressure to draw milk from the breast. When the frenulum limits these movements, the baby may compensate with other oral muscle groups — leading to ineffective milk transfer, pain for the nursing parent, and fatigue for the baby.

Lip tie — a tight or thick frenulum connecting the upper lip to the gum — is often discussed alongside tongue tie, as it can also affect the quality of the latch. However, lip ties are considered less clinically significant than tongue ties in most cases, and should be evaluated in the context of the overall feeding picture rather than treated automatically.

Signs of Tongue Tie in Breastfeeding

It is important to note that these signs can have causes other than tongue tie. A lactation consultation is the right first step — it can determine whether the symptoms are related to tongue tie, positioning and latch, supply dynamics, or another factor entirely.

Tongue Tie Evaluation: What It Involves

At Birthstone Women's Wellness, tongue tie evaluation is part of a comprehensive lactation consultation. We do not look at anatomy in isolation — we assess the feeding as a whole. A functional evaluation includes:

• Detailed feeding history — how long, how often, what you and baby are experiencing
• Observation of a full feeding to assess latch quality, milk transfer, and baby's oral movements
• Oral anatomy assessment — examining the frenulum, tongue mobility, palate structure, and lip attachment
• Suck assessment — evaluating the strength, coordination, and pattern of baby's suck
• Weighted feed when indicated — measuring actual milk transfer

The goal of this evaluation is not to identify every anatomical variation — it is to determine whether and how the anatomy is affecting the feeding. A frenulum that looks tight may not be causing functional problems. A frenulum that looks mild may be causing significant pain and transfer issues. The feeding picture tells us more than the anatomy alone.

Does Every Tongue Tie Need Treatment?

No — and this is an important point. The presence of a tongue tie on exam does not automatically mean revision is necessary. The decision about whether to pursue frenulotomy (revision of the frenulum) should be based on the functional impact on feeding — how is the tie actually affecting the latch, milk transfer, weight gain, and maternal comfort?

Many mild tongue ties can be managed effectively with improved positioning, latch work, and bodywork or oral exercises, without surgical intervention. Others cause significant enough functional impairment that revision is clearly indicated. A lactation consultant can help you understand the functional picture and, when revision is appropriate, provide referrals to experienced pediatric dentists or ENTs who perform frenotomy.

We encourage families to approach tongue tie treatment decisions with both thorough assessment and time for informed consent. There is no urgency to revise without functional evidence that the tie is causing the problems.

After Revision: What to Expect

If revision is performed, follow-up lactation support is an essential part of recovery. The revision itself releases the restriction — but the baby may still have compensatory oral muscle patterns that need to be retrained. Post-revision lactation consultations help ensure that the revised tongue is being used effectively at the breast, that latch is improving, and that any oral exercises are being performed correctly.

We offer post-revision follow-up consultations and work closely with families throughout the recovery period to ensure that the expected improvements in feeding are actually happening.
