Tongue-Tie and Lip-Tie (Frenulum) in Children: Diagnosis, Symptoms, Treatment Guide

What Is a Frenulum? Mucosal Folds Inside the Mouth

A frenulum is a thin mucosal fold that attaches one structure to another within the mouth. Oral anatomy includes four main frenula: lower lip (labial inferior), upper lip (labial superior), under the tongue (lingual), and inside the cheek (buccal). These structures exist in all infants; they only cause functional loss when they are thick, short, or incorrectly positioned.

Two main structures should be evaluated from birth: the **lingual frenulum (tongue-tie)** and the **labial frenulum (upper lip-tie)**. The tongue-tie may prevent the infant from properly positioning the tongue during breastfeeding; the upper lip-tie may create a diastema (gap) in the upper primary teeth region and complicate hygiene.

The pediatric dentist evaluates both frenula at the first visit. If there is no structural problem, no intervention is needed; if functional loss is present, frenectomy (division) or laser frenotomy is planned.

Tongue-Tie (Lingual Frenulum) — Symptoms and Diagnosis

The lingual frenulum is the thin mucosal structure that connects the underside of the tongue to the floor of the mouth. In abnormal cases it restricts tongue range of motion — this condition is called **ankyloglossia**. Prevalence ranges between 4-11%.

**Tongue-tie symptoms in infants (0-12 months):**

Breastfeeding difficulty — the baby cannot maintain a proper latch, frequently breaks suction, and weight gain is slow. The mother experiences nipple pain, cracking, and mastitis. This is the most clinically critical sign.

Tongue tip shape — a normal tongue has a flat or slightly rounded tip. With tongue-tie, the tip shows a V- or heart-shaped notch.

Limited tongue elevation — when the baby opens the mouth, the tongue cannot reach the palate.

**Tongue-tie symptoms in children (1+ year):**

Speech disorders — particularly articulation difficulties with the sounds "l, r, t, d, s, z." The "r" sound is the most frequently affected.

Inability to reach the palate with the tongue — inadequate tongue posture during swallowing and chewing.

Social effects — from adolescence onward, restrictions in social actions like kissing or sticking out the tongue.

Dental hygiene — plaque and gingivitis tendency in posterior teeth that the tongue cannot clean.

Lip-Tie (Labial Frenulum) — Symptoms and Diagnosis

The upper labial frenulum connects the inner surface of the upper lip to the front gum line (alveolar band). It is prominent in all infants and thins with age. When it causes problems, it is referred to as **frenum eninjesta** or **labial tie**.

**Lip-tie symptoms in infants:** During breastfeeding the baby cannot flange the upper lip outward (does not achieve the "fish lips" position); maternal nipple fatigue and insufficient milk transfer are seen. In some infants it is observed together with tongue-tie.

**Lip-tie symptoms in children:** A **diastema** (1-3 mm gap) between the upper incisors — particularly persistent between ages 4-10. When the upper lip is tightly attached to the gum, brushing becomes difficult and plaque accumulates; gingivitis and primary tooth decay risk increase.

**What happens if the upper lip-tie tears?** — Labial frenulum tearing after a fall or impact is one of the most common oral traumas in childhood. It is usually not a medical emergency and heals spontaneously. If active bleeding does not stop within 10 minutes, a pediatric dental or emergency room evaluation is essential.

Diagnosis is made by pediatric dental examination and panoramic radiograph if needed. An upper incisor diastema may not be due solely to the labial frenulum — mesiodens (supernumerary tooth) or permanent tooth agenesis must also be evaluated.

Frenectomy and Laser Frenotomy — Treatment Methods

Frenulum treatment is indicated only when there is **functional loss**; the visible presence of the frenum alone is not a treatment indication. The decision is made jointly by the pediatric dentist, ear/nose/throat specialist (if needed), and lactation consultant (for infant breastfeeding issues).

**Classic Frenectomy (surgical division):** The frenulum is cut with scissors or a scalpel under local anesthesia. The procedure takes 5-10 minutes. Healing is 7-10 days; small sutures dissolve or are removed at 5-7 days. In infants, anesthesia-free quick division (first 6 months) is debated; some protocols use topical local anesthetic.

**Laser Frenotomy:** The frenulum is vaporized with a diode or Er:YAG laser. Advantages: minimal bleeding, no sutures needed, faster healing (3-5 days). Child comfort is higher. Clinical outcomes are similar compared with classic frenectomy; technique choice depends on clinic equipment and clinician experience.

**Age and timing:** If there is a tongue-tie breastfeeding problem, 0-3 months is the most appropriate window (lactation continues so recovery is rapid). For speech, the decision can be made before age 3-4. For upper lip-tie diastema, full eruption of permanent teeth (age 8-10) is awaited — some cases show spontaneous closure.

**Post-procedure care:** Soft-cold food (yogurt, ice cream) for the first 24 hours. Reminding the child not to manipulate the area with fingers. Pediatric dental follow-up at 1 week; tongue exercises (directed by lactation consultant or speech therapist) must begin during the healing period.

Tongue-Tie and Speech — A Logopedic Approach

Tongue-tie division alone does not correct speech problems. Because the child has used the tongue in a restricted manner for years, motor patterns are established; **speech therapy (logopedics)** is mandatory after frenectomy.

Typical treatment protocol: frenectomy → 1 week healing → speech therapy initiation (1-2 sessions per week). Target sounds: especially /r/, /l/, /t/, /d/. The process may last 3-12 months depending on the child's age.

In very young children (0-3 years) who have undergone early frenectomy, motor restriction due to tongue-tie has not yet developed; therefore speech therapy may not be needed. The decision is a joint pediatric dentist + speech therapist evaluation.

At-home parental support: tongue exercises ("tongue up, tongue down, tongue right, tongue left"), touching the palate with the tongue tip, lip closing-opening. These exercises support both post-operative healing and motor learning.

Frenectomy — Complications and Important Warnings

Frenectomy is a low-risk procedure but rare complications can occur:

Bleeding: Minor bleeding in the first 30 minutes is normal. If active dripping continues after 1 hour, contact the pediatric dentist.

Infection: Below 1% incidence. Signs: fever, swelling, foul odor. Antibiotics may be required.

Reattachment: If tongue exercises are not performed after frenectomy, the frenulum can reattach at the same site. For this reason, exercises are mandatory for 4-6 weeks.

Anesthesia reaction: Very rare. Pre-op medical history review minimizes risk.

**Tongue-tie in adults:** Frenectomy is possible after age 18, but because the motor pattern is firmly established, speech therapy outcomes are limited. Early intervention is always more advantageous.

Frenectomy in Ataşehir — Our Pediatric Dental Approach

At our clinic in Flora Residence, frenectomy evaluation begins as a pediatric dental examination. At the first visit:

Clinical examination determines the severity of tongue-tie/lip-tie (Coryllos or Hazelbaker scale).

Breastfeeding history, speech assessment (age-appropriate), and family history are taken.

If treatment is indicated, the technique (classic or laser) is selected together with the mother. Laser frenotomy is our preferred standard.

The procedure is usually completed in a single visit; coordination with a lactation consultant is provided for infants.

Next steps: follow-up at 1 week, tongue exercise protocol, referral to a speech therapist if needed. Follow-up visits are repeated at 1 month and 3 months.

If your baby has breastfeeding difficulty, weight gain problems, or your child has a speech disorder, you can schedule an appointment for a tongue-tie/lip-tie evaluation.
