A toddler lip tie looks different from what you saw in those early nursing days. Dr. Susan Kim at Evergreen Pediatric & Airway Dentistry in Kirkland, WA evaluates lip tie in toddlers. She trained at Columbia University College of Dental Medicine and holds LightScalpel CO2 laser certification. Families across Kirkland, Juanita, and Finn Hill trust her to explain what the tissue is doing now.
The feeding problems parents noticed in infancy often feel resolved by toddlerhood. What stays behind is subtler. Persistent tooth gaps, picky eating, or muffled speech can point back to the same tissue. Addressing them while the jaw is developing gives Dr. Susan more options and your child more time to benefit.
What Is a Lip Tie in a Toddler?
A lip tie in a toddler is a tight frenulum. This tissue connects the upper lip to the gum above the front teeth. When it is too short or thick, it limits lip movement. In toddlers ages 1 to 4, the restriction shows up in chewing, speaking, and jaw development.
Dr. Susan grades lip ties 1 through 4, with grade 3 and 4 causing the most functional problems. Grade 3 and 4 ties appear in about 10 to 12 percent of children. The tissue does not loosen as a child grows. What changes is how that restriction limits function at each new stage.
How Does a Lip Tie Show Up Differently in Toddlers?
In the infant stage, a lip tie mostly affects the latch and milk transfer. Once a child moves to solid foods, the restriction shifts to chewing. Toddlers with a grade 3 or 4 tie often push food to the sides of the mouth. They reject foods with tougher textures. Parents near 116th Ave NE in Kirkland describe their toddler as extremely picky. They rarely realize the refusals are partly mechanical.
Speech development brings a second set of signals. The upper lip helps form sounds like “m,” “b,” “p,” and “f.” A lip tie does not cause speech delay on its own. It can make those sounds harder to produce clearly. Children who drop lip-dependent consonants sometimes have a frenulum problem a speech therapist alone cannot fully correct.
The third shift happens as the front teeth erupt. A grade 3 or 4 frenulum that inserts low on the gum can push developing teeth apart. That creates a midline diastema, the gap between the upper front teeth. Dr. Susan watches for this in children ages 3 to 6 with a tie that was never released.
What Signs Should Kirkland Parents Watch For?
Parents often notice something is off well before a clinician names it. Each sign has an innocent explanation on its own. Together, they form a pattern worth bringing to Dr. Susan at her office near Totem Lake Blvd NE. She looks at the whole functional picture, not just one symptom.
Watch for these signs in toddlers ages 1 to 4:
- Food pocketing or pushing solids to the cheeks
- Refusing chewy or tough textures beyond typical preferences
- Difficulty with lip-dependent sounds like “m,” “b,” or “p”
- A gap forming between the two upper front teeth
- Mouth breathing at rest with the lip slightly open
- Drooling past age 3 without another clear cause
- Upper lip that cannot fully cover the top teeth at rest
None of these signs confirm a lip tie on their own. Each one is a reason to schedule a functional evaluation. Dr. Susan checks the frenulum’s length, insertion point, and range of motion, then tells you what she finds.
How Do You Compare a Mild Versus a Significant Lip Tie?
Severity determines whether a toddler needs treatment now, later, or not at all. Dr. Susan grades every frenulum 1 to 4. The grade reflects where the tissue inserts and how much movement it limits. A grade 1 tie is thin and rarely causes problems. A grade 4 tie wraps around the gum and extends toward the palate.
This table shows how grade affects function in toddlers:
| Grade | Insertion Point | Functional Impact | Typical Recommendation |
| 1 | At gum margin | Minimal to none | Monitor |
| 2 | Mid-gum | Mild restriction | Monitor with checkpoints |
| 3 | Near palatal edge | Feeding and speech effects | Evaluate for release |
| 4 | Into papilla or palate | Significant restriction | Release recommended |
The table is a framework, not a diagnosis. Dr. Susan bases her recommendation on what the tissue can do during a full functional exam. The grade alone does not decide. A grade 3 tie with no functional symptoms may need only monitoring. A grade 2 tie paired with speech or eating difficulties may warrant a closer look.
What Does Dr. Susan Look For at an Evaluation?
What Does Dr. Susan Look For at an Evaluation?Dr. Susan combines parent history with a direct clinical examination. She asks about nursing history, solid food progression, and any speech concerns. Then she assesses the frenulum through physical examination and functional movement tests. Families near Juanita Drive NE say it is the first time the whole picture came together at once.
She examines these specific points during every toddler lip tie evaluation:
- Frenulum length, width, and insertion point on the gum
- Upper lip range of motion with the lip elevated and curled
- Position of the upper incisors and presence of a midline gap
- Tongue function, since tongue tie often appears alongside a lip tie
- Parent-reported eating, chewing, and texture preferences
- Speech sound production for lip-dependent consonants
Dr. Susan explains every finding in plain language. She shows parents what she sees and tells them what it means. You leave with a clear picture of what the tissue is doing and what to do next.
When Is the Right Time to Treat a Toddler’s Lip Tie?
Timing depends on what the tie is currently doing. A grade 3 or 4 tie with clear feeding or speech difficulty warrants early laser release. The jaw is still developing. Tissues heal faster in younger children. Read more about Dr. Susan Kim’s training and background to understand the experience behind those decisions.
For mild ties without functional symptoms, watchful waiting is reasonable. Dr. Susan sets monitoring checkpoints rather than leaving families without a plan. She tracks gap widening, speech sound development, and whether eating patterns suggest a mechanical problem. Families near 132nd Ave NE who choose monitoring get a clear set of signals to watch for. When a release becomes appropriate, the tongue and lip tie evaluation at Evergreen Pediatric walks through every step.

Frequently Asked Questions
Can a toddler outgrow a lip tie on their own?
The frenulum tissue does not change or loosen as a child grows. A grade 3 or 4 tie that causes problems at age 2 will still cause them at age 5, though symptoms shift from feeding to eating and speech. The window for treatment closes faster than most parents expect. The AAPD’s 2022 guidance addresses this in its policy on pediatric frenulum care.
Does a lip tie always cause a gap between the front teeth?
Not every toddler with a lip tie develops a midline diastema, and not every tooth gap comes from a lip tie. A 2023 review in Dental Update found that a low-inserting frenulum is frequently associated with a gap, but the evidence does not confirm a direct causal link. It recommends evaluating timing carefully in its review of frenectomy and diastema management. Dr. Susan evaluates the frenulum’s insertion point and the overall bite before recommending treatment.
Is laser frenectomy safe for toddlers?
Laser frenectomy is well tolerated in children when performed by a trained clinician. A 2022 cohort study of 109 children found laser release produced meaningful diastema reduction with minor discomfort and swelling. The study’s findings on frenectomy safety and efficacy in children support its use as a safe office procedure. Dr. Susan uses a LightScalpel CO2 laser, which seals tissue as it works and eliminates the need for sutures in most cases.
When should a toddler’s lip tie be treated versus monitored?
Treatment timing depends on functional impact, not grade alone. A 2025 narrative review in Dentistry Journal found insufficient evidence to support early prophylactic frenectomy and recommends conservative monitoring in low-grade cases, as outlined in its analysis of frenectomy timing for labial frena. Dr. Susan follows that same principle.
