Does My Child Need Orofacial Myology? Signs to Look For (A Guide for Blackburn, Box Hill & Doncaster Families)
Many parents first hear the term “tongue thrust” or “myofunctional disorder” from a dentist, orthodontist, or speech pathologist. But how do you know if your child really needs orofacial myology?
Here are the most common signs, explained simply.
1. Long-term thumb/finger sucking or dummy use
If sucking habits continue past age 3–4, they can change:
- the shape of the palate
- tongue posture
- dental alignment
Myofunctional therapy helps eliminate habits and correct muscle patterns.
2. Mouth breathing (instead of nose breathing)
Children who often have their mouth open — especially at rest or during sleep — may develop:
- low tongue posture
- weak lip closure
- narrow palate
- sleep concerns
- dental crowding
Mouth breathing is a major red flag for a possible myofunctional issue.
3. Persistent lisp or unclear “S” and “Z” sounds
If your child’s lisp hasn’t improved with traditional speech therapy, the tongue position may be the underlying problem.
Myofunctional therapy trains:
- correct tongue rest
- correct swallow
- stable oral posture
…which often clears the lisp more effectively.
4. Unusual swallowing patterns
Look for:
- the tongue peeking out between teeth
- lips staying open during a swallow
- dribbling or food escaping the mouth
This often indicates a tongue thrust swallow.
5. Dental or orthodontic concerns
If your child has:
- open bite
- protruding teeth
- flared top incisors
- relapse after braces
…an orthodontist may suspect poor tongue or lip posture.
Myofunctional therapy can prevent teeth from shifting back after braces.
6. History of tongue-tie
After a tongue-tie release, children may need help learning:
- how to move their tongue properly
- where to rest it
- how to swallow without compensations
Myofunctional therapists retrain the new movement pattern.
7. Excessive drooling beyond toddler age
This may be a sign of weak lip or cheek muscle tone.
When should you seek help?
Ages 6–8 are common for full therapy programs (when adult teeth start emerging), but children as young as 3–4 can begin habit elimination or tongue posture work.
Early support = better long-term outcomes.
