Severe Crowding and Lip Strain: What It Is and How Armadale Orthodontists Treat It
Have you ever noticed a teenager: or maybe your own child: whose lips look tight, strained, or a little “full” even when their mouth is completely at rest? That’s not just a facial quirk. It’s often a visible sign of severe dental crowding pushing outward against the lips, and it’s more common than most people realise.
In Australia, the prevalence of severe and handicapping malocclusions is approximately 30% in the 12–14-year-old population PubMed Central: meaning nearly one in three teenagers could be dealing with some degree of significant dental misalignment. And in many of those cases, lip strain is one of the first things parents and patients notice.
This isn’t just a cosmetic concern, either. Lip strain signals a functional bite problem: one that, left untreated, can affect breathing, oral health, and long-term dental structure. At Michael Woods Orthodontics, our specialist team near Armadale sees this presentation regularly, and we know exactly how to assess and treat it properly.
What Is Lip Strain in Orthodontic Terms?
To understand lip strain, it helps to know what’s happening beneath the surface.
When teeth are severely crowded, the lips have to work harder than normal just to keep the mouth closed while resting. Normally, the lips should close together without any effort at all. But when crowded teeth push forward, the lip muscles: particularly the mentalis (the chin muscle): have to contract and strain to bring the lips together.
The result? A bunched, tense chin, lips that look pursed or pushed, and visible tension in the lower face even when the person isn’t speaking or eating. It’s one of those things that, once you know what you’re looking at, you start noticing it everywhere.
This is what orthodontists refer to as lip incompetence: the inability to close the lips without muscular effort. It’s clinically significant because it points to a structural problem with how the teeth and jaw are positioned.
Why Severe Crowding Causes Lip Strain: and What's Really Going On
Here’s the simple version: when there isn’t enough space in the dental arch for all the teeth to fit, they crowd beyond their intended positions. The front teeth: both upper and lower front teeth: end up pushed forward. The lips, which naturally rest against the front surface of the teeth, are then pressed outward.
To compensate, the lips strain inward. Over time, this becomes a habitual muscle tension pattern.
In younger patients, this can also trigger mouth breathing as a secondary habit. When the lips struggle to close comfortably, the natural response is to breathe through the mouth instead: which introduces its own set of dental and developmental concerns. Dentists and orthodontists watching for orthodontic problems in growing children are trained to look for these secondary signs alongside the crowding itself.
The relationship between dental crowding and lip incompetence is well-recognised clinically, and it’s one of the key reasons why orthodontic treatment for crowding often results in such noticeable improvements to facial appearance as well as function.
Other Signs That Often Come With Lip Strain
Lip strain rarely shows up alone. There are several accompanying signs that suggest crowded teeth may be the culprit:
- Visibly bunched chin: the mentalis muscle looks raised or dimpled, even at rest
- Lips that don’t touch at rest: a gap between upper and lower lips when the face is relaxed
- Teeth visible at rest: protruding teeth peek through when the mouth isn’t actively open
- Lower face appearing pushed forward: the profile shows the chin and lips sitting ahead of where they should be
- Deep lines around the lips: the constant muscular effort accelerates the appearance of strain lines above and below the lips
It’s worth noting that not all lip strain comes from dental crowding. Sometimes the jaw itself is the contributing factor: a skeletal issue rather than a purely dental one. That’s why a specialist assessment is so important. A dentist may spot the concern, but it takes a specialist orthodontist to properly distinguish between dental and skeletal causes and plan treatment accordingly.
If you’ve noticed any of these signs in your child: or yourself: and you’re in the Armadale area, it’s worth booking an assessment.

Treatment Approach at Michael Woods Orthodontics
Getting the right outcome for lip strain and severe crowding starts well before any orthodontic treatment actually begins. Here’s how we approach it.
1. Comprehensive Assessment First: No Guesswork
Before we recommend any treatment options, we take full orthodontic records. This includes side-profile photos, panoramic and lateral cephalometric x-rays, and digital scans of your teeth and jaw.
This step isn’t optional. Proper orthodontic treatment cannot be planned without understanding the full picture of how your teeth, jaw, and facial profile relate to one another. Attempting to treat severe crowding without full records would be like trying to renovate a house without a floorplan.
Professor Michael Woods has extensive experience in complex orthodontic assessment, and every patient who comes to us receives a thorough evaluation before any orthodontic treatment is recommended.
2. Tooth Extraction If Required: A Clinical Decision, Not a Cosmetic One
In severe cases of dental crowding, there simply isn’t enough space for the teeth to fit into the correct position without creating that space first. Strategic tooth extraction: typically involving premolars: is sometimes necessary to give the remaining teeth room to move into alignment.
This is a decision that’s always driven by clinical need, not cosmetics. Tooth extraction as part of orthodontic treatment is well-established and widely used. Professor Woods is highly experienced in extraction-based orthodontic treatment and will explain clearly whether this is the right approach for your situation.
3. Fixed Braces to Align and Retract the Teeth
Once space is created (where needed), fixed braces: including both traditional braces and metal braces: are used to move teeth back into proper alignment. Braces work by applying continuous, controlled pressure to move teeth into their ideal positions, reducing the forward pressure on the lips.
Here’s the encouraging part: as the teeth begin to move, lip strain visibly reduces. Many patients and parents notice a difference in facial appearance within 6–9 months of active orthodontic treatment: well before the braces come off. By the time treatment is completed, the improvement to both appearance and function is typically dramatic.
Braces remain the most effective and reliable treatment method for severe crowding with lip strain, particularly in cases requiring significant tooth movement.
4. Clear Aligners: Are They an Option?
Clear aligners (including clear aligner treatment options like Invisalign) can be highly effective for mild to moderate crowding. However, for severe cases involving significant dental crowding and lip strain, fixed braces typically provide more precise control over tooth movement.
Clear aligners are a discreet treatment option and can be appropriate in some presentations of severe crowding: but this is assessed case by case. Your specialist will discuss the full range of treatment options with you and help you understand which approach is best suited to your specific situation. For patients wanting a more discreet treatment option, clear aligner treatment may be considered alongside or instead of traditional braces depending on the complexity.
5. Long-Term Retention
Once braces are removed and the teeth are straight, retention is essential. Without a retainer, teeth may drift back toward their original positions: a process called relapse.
At Michael Woods Orthodontics, we provide retainers as part of your orthodontic care plan. Both fixed and removable retainer options are available depending on what suits your teeth and lifestyle. Wearing your retainer as directed is the single most important thing you can do to protect your long-term dental health after treatment.
How Long Before Lip Strain Starts to Improve?
This is one of the most common questions we hear from patients and parents: and it’s a completely fair one to ask.
The good news is that improvement tends to happen progressively throughout active treatment, not just at the end. As crowding is reduced and the teeth move into better alignment, the lips gradually have less to push against. Most patients notice early improvement in lip tension within the first several months of wearing braces.
Full improvement: where the lips rest comfortably without strain and the facial profile has settled: is typically seen once treatment is completed and the teeth are in their final positions. With proper retention, these results are long-lasting.
Early orthodontic intervention (particularly in adolescents whose jaws are still developing) can also produce faster and more stable results, which is why we always recommend getting an assessment as soon as concerns arise rather than waiting.

Frequently Asked Questions
Will removing teeth make my face look sunken?
No: when extraction is done as part of a well-planned treatment, it won't cause a sunken appearance. For patients with protruding teeth and lip strain, it often improves the facial profile. Professor Woods always assesses whether extraction is clinically appropriate before recommending it.
Can Invisalign treat severe crowding with lip strain?
It depends on the severity. Clear aligners work well for mild to moderate crowding, but severe cases usually call for fixed braces. We assess this individually and will walk you through all your treatment options at your consultation.
How do I know if my lip strain is from crowding or something else?
The only reliable way to know is a specialist assessment. We take full records: photos, x-rays, and digital scans: to determine whether your teeth, jaw, or both are contributing. We won't recommend treatment unless the records support it.
At what age should I bring my child in?
You don't need to wait for all permanent teeth to come through. An assessment around age 7–10 can catch developing problems early. If you're noticing crowding, lip strain, or mouth breathing, book an assessment sooner rather than later.
Will crowding make oral hygiene harder with braces?
Yes: overcrowded teeth already make cleaning trickier, and braces add to that. We give every patient thorough oral hygiene instructions at the start of treatment, and regular check-ups with your dentist throughout are strongly recommended.
