When NOT to Worry About Tongue Tie: Overdiagnosis in Newborns

I need to have an honest conversation about something happening in newborn care right now: tongue tie is being over-diagnosed. As someone who evaluates and treats tongue ties regularly, I say this not to dismiss the condition—which is very real and very impactful when present—but to help parents navigate a landscape where some providers see tongue tie everywhere they look.

The Rise of Tongue Tie Diagnosis

Tongue tie diagnosis rates have increased dramatically over the past 15 years. Frenotomy rates in the US have risen nearly tenfold. Is this because we're better at identifying a condition that was previously missed? Partially, yes. Is it also because some providers are diagnosing and treating ties that don't need intervention? Also yes.

The internet has amplified this. Parents googling breastfeeding difficulty will quickly find "tongue tie" as a potential cause. Some online communities present it as the answer to nearly every feeding problem. And some providers have built practices around identifying and releasing ties—creating a financial incentive to diagnose.

None of this means tongue tie isn't real. It means the diagnostic landscape is complicated, and parents deserve honest information.

When a Tie ISN'T the Problem

Here are situations where I commonly see tongue tie blamed for problems it isn't causing:

Normal Early Breastfeeding Challenges

The first 1–2 weeks of breastfeeding are hard for almost everyone. Sore nipples, latch learning, milk coming in—these are normal adjustment issues that resolve with time and basic support. Jumping to a tongue tie diagnosis in the first few days, before breastfeeding has had a chance to establish, often leads to unnecessary intervention.

Anatomy Without Dysfunction

Every baby has a lingual frenulum. In some babies, it's more prominent than in others. A visible frenulum is NOT the same as a tongue tie. The diagnosis should only be made when the frenulum restricts tongue function enough to cause feeding problems.

I've seen babies diagnosed with "posterior tongue tie" based on someone lifting the tongue and seeing a frenulum—which, again, every baby has. Without functional impairment, this isn't a diagnosis that needs treatment.

Symptoms With Other Causes

• Painful latch → May be positioning, not tongue tie
• Clicking during feeding → May be oversupply causing baby to break seal from fast flow
• Gas and fussiness → Normal infant GI development, not necessarily from air swallowing due to a tie
• Slow weight gain → Many potential causes including insufficient feeding frequency, maternal supply issues, or medical conditions
• Nipple damage → May be from incorrect positioning or baby's bite pattern, not a frenulum restriction

When Baby Is Feeding Well

If your baby is latching without pain, gaining weight well, and producing adequate wet and dirty diapers—they don't have a functionally significant tongue tie, regardless of what their frenulum looks like.

Red Flags for Overdiagnosis

Be cautious if:

The diagnosis is made without watching a feeding. Any provider who diagnoses tongue tie from a quick peek in the mouth without observing how baby actually feeds is not doing a thorough evaluation.

The provider diagnoses nearly every baby they see. If their diagnosis rate is very high (some providers claim to find tongue ties in 50%+ of babies they evaluate), the threshold may be too low.

There's pressure to do the procedure immediately. A legitimate provider will give you time to think, get a second opinion, and explore alternatives. "We should do it today before it gets worse" is a pressure tactic, not standard medical practice. Young infants don't need to be released urgently unless there's a medical emergency.

The provider doesn't discuss alternatives. Frenotomy should be presented as one option alongside conservative management and lactation support—not as the only path forward.

The cost seems unusually high. Particularly for laser procedures in private practice settings where the fee may not be covered by insurance. This doesn't automatically mean the provider is wrong, but it's worth noting the financial dynamic.

Getting a Second Opinion

If someone has diagnosed your baby with a tongue tie and recommended a frenotomy, it's completely reasonable to:

• Ask a different pediatrician or ENT for a second evaluation
• See a lactation consultant (IBCLC) who can assess whether latch technique might be the issue
• Try conservative management (positioning, lactation support) for 1–2 weeks before proceeding
• Ask your provider to explain specifically how the tie is affecting feeding function

A provider who is confident in their diagnosis will welcome a second opinion. One who discourages it should raise questions.

My Balanced Approach

I diagnose and treat tongue ties when they're functionally significant. That means:

1. Symptoms exist — Pain, poor weight gain, inefficient feeding
2. Anatomy matches — A restricted frenulum that explains the symptoms
3. Function is impaired — I can see and feel the restriction during feeding observation and oral exam
4. Conservative measures haven't helped — Or the severity warrants earlier intervention

When all four criteria are met, I recommend frenotomy with confidence that it will help. When they're not all met, I recommend addressing the actual cause—which may be latch technique, supply, positioning, or simply time.

The Bottom Line

Tongue tie is a real condition that causes real problems for some breastfeeding families. Treatment, when indicated, can be transformative. But not every breastfeeding difficulty is caused by a tongue tie, and not every frenulum is a tongue tie.

The best care comes from providers who evaluate function, not just anatomy—who consider the full picture of your breastfeeding experience—and who are as comfortable saying "this isn't a tie" as they are recommending a release.

If you're unsure, get a thorough evaluation from someone who takes the time to watch a feeding, assess oral function, and discuss all your options. That's the care you and your baby deserve.
