Invisalign has changed the way we approach orthodontic correction. For patients who require alignment but prefer to avoid brackets and wires, clear aligners offer an effective alternative grounded in both biomechanics and patient lifestyle needs.
At East River Dental, we incorporate Invisalign into daily clinical work — not because it’s trendy, but because in the right case, it produces excellent outcomes. From adult professionals to teenagers entering alignment at the right developmental stage, Invisalign can be a strong solution — if the case is chosen properly and the patient understands the process.
This guide will walk you through what Invisalign is, how it works, who it suits, and where it fits in the broader scope of orthodontic treatment in Ontario.
What is Invisalign?
Invisalign is a custom clear aligner system that incrementally moves teeth using a sequence of thermoplastic trays. Unlike fixed appliances, the trays are removable and designed to shift dentition with targeted force — addressing crowding, spacing, crossbite, or mild-to-moderate overbite/underbite concerns.
Each aligner is worn 20–22 hours per day and is changed approximately every 7–14 days, depending on the case progression.
The material used — SmartTrack® — offers flexibility with control. It doesn’t warp under normal use and has shown superior fit retention compared to earlier aligner systems. Each tray is digitally mapped and fabricated using CAD/CAM software.
How It’s Made
Each tray is made from SmartTrack®, a patented thermoplastic that applies controlled pressure to guide tooth movement. The trays are fabricated based on a 3D treatment plan and are changed approximately every 1–2 weeks.
Customization Process
Unlike traditional braces, which rely on mechanical force from wires and brackets, Invisalign trays apply surface pressure to specific teeth, using a digital model to pre-sequence each movement. Attachments (small, tooth-coloured composite bumps) may be bonded to certain teeth to enhance control.
Who It’s For
Invisalign is indicated for patients with:
- Mild to moderate crowding or spacing
- Class I or mild class II malocclusion
- Overbite or open bite (in select cases)
- Relapse after previous orthodontic treatment
It’s suitable for both adolescents and adults, though compliance requirements are higher than with fixed appliances.
Clinical Distinction
Clear aligners differ from braces not only in visibility but in how they deliver force. Braces apply continuous mechanical pressure using wires and brackets. Invisalign relies on controlled surface pressure through the tray interface, often supported by attachments — small tooth-coloured buttons temporarily bonded to the enamel to guide specific movements.
How Does Invisalign Work?
The Invisalign system depends on case selection, digital planning, patient compliance, and biological response.
The Invisalign Process:
- Assessment and Diagnosis
Using digital scanning (iTero) and bite analysis, we determine whether the patient is a suitable candidate. We assess spacing, rotations, incisor angulation, occlusion, and root parallelism. - Treatment Planning
The scan is used to generate a digital model. Each aligner stage is planned, with specific tooth movements sequenced to avoid interference or relapse. - Aligner Fabrication
The lab produces the full set of aligners, often with intermediate revisions if refinements are anticipated. Most patients receive 14–30 aligners per arch. - Wearing the Aligners
Aligners are worn nearly full time and only removed for eating, brushing, or flossing. Each new tray builds upon the movement of the previous one. - Monitoring
We assess progress every 6–8 weeks. Compliance, tray fit, and tissue health are reviewed. Mid-course corrections or attachments may be adjusted. - Retention
After alignment is complete, a custom retainer is worn. Without retention, relapse is expected.
Benefits of Invisalign
When properly selected and supervised, Invisalign delivers stable results with several practical advantages.
Discreet Appearance
This is often the driving factor. Many adults and teens decline treatment due to the aesthetics of braces. Invisalign aligners are nearly invisible in social and professional settings.
Improved Oral Hygiene
Brackets trap plaque and require meticulous hygiene. With Invisalign, trays are removed for cleaning, allowing patients to brush and floss normally.
Dietary Freedom
There are no food restrictions. Aligners are removed before eating, meaning hard, sticky, or fibrous foods don’t interfere with treatment or damage components.
Fewer Emergencies
Bracket debonding and wire breakage are common in braces. Invisalign eliminates most mechanical emergencies, though tray loss or warping can still occur.
Predictability
Thanks to digital mapping, we can simulate Invisalign before and after outcomes, identify risk points in movement sequencing, and visualize potential refinements early.
Potential Drawbacks and Considerations
Invisalign is not for everyone — and it’s not an automatic substitute for braces.
Patient Compliance
Because aligners are removable, success is tied to discipline. Aligners must be worn 20–22 hours daily. Underwear time or casual noncompliance significantly affects outcomes.
Case Limitations
Severe rotations, open bites with skeletal origins, or complex class II or III malocclusions may require traditional orthodontic intervention. While Invisalign can address many moderate cases, skeletal discrepancies require tools beyond tray pressure.
Financial Consideration
Invisalign cost in Ontario typically ranges from $4,500 to $7,500, depending on case complexity and refinements. Coverage varies between insurance plans. Some include partial coverage under orthodontic services; others do not. Our team provides pre-treatment estimates and insurance coordination during the Invisalign consultation.
Invisalign vs. Traditional Braces
For patients deciding between Invisalign vs braces, clinical factors and lifestyle considerations both weigh in.
| Factor | Invisalign | Traditional Braces |
| Visibility | Nearly invisible | Very visible |
| Removability | Removable during meals and hygiene | Fixed |
| Hygiene | Easier; no obstacles | More difficult; requires floss threaders |
| Comfort | Smooth tray edges | Potential for lip/cheek irritation |
| Complex Cases | Limited (moderate only) | Suitable for severe malocclusions |
| Adjustments | Minimal chair time | Regular wire adjustments |
| Compliance | Requires consistent wear | Passive once placed |
Our recommendation is case-specific. A 14-year-old with class II crowding and developing canines may do better in braces. A 42-year-old professional with anterior crowding and healthy bone may be ideal for Invisalign.
Invisalign for Adults and Teens
Both adults and teens benefit from Invisalign, but candidacy and compliance expectations vary.
Invisalign for Adults
Adults often prioritize discreet aesthetics and appreciate the predictability of digitally planned treatment. We often see adult patients returning to orthodontics after relapse from childhood braces or seeking alignment for restorative or cosmetic planning (e.g., veneers or implants).
Invisalign for Teens
Invisalign Teen is designed with eruption tabs and compliance indicators, helping ensure effective wear in growing patients. However, not every teenager is suited — maturity and commitment matter.
Parental supervision, regular hygiene, and follow-up compliance must be factored in. When managed well, Invisalign offers teens a non-invasive path to correction during critical growth phases.
Invisalign Treatment at East River Dental
We provide East River Dental Invisalign care based on clinical alignment, not trend or demand. Each case is reviewed for candidacy using radiographs, 3D scans, and occlusal analysis.
Invisalign Maintenance
Patients must care for their trays and oral environment consistently.
- Rinse trays with cool water (not hot) to avoid warping.
- Clean trays with a soft brush and unscented soap or Invisalign crystals.
- Store aligners in their case — not in pockets or napkins.
- Avoid soaking trays in mouthwash (which can stain or degrade material).
Aligners should not be used while eating or drinking anything other than water. Doing so can lead to breakage, staining, or bacterial growth.
Why patients choose us:
- Full in-house scanning and planning — no mailing molds or outsourced imaging
- Precision tray fitting and attachment placement
- Regular review intervals for accountability and adjustment
- Invisalign for teens and adults, adapted to compliance and growth stage
- Transparent discussions around Invisalign maintenance, retention, and cost
We track every case digitally, so if refinements or mid-course corrections are needed, we don’t rely on guesswork — we have the data.
Conclusion
Invisalign is a proven option in modern orthodontics. For properly selected cases, it offers predictable movement, aesthetic appeal, and patient convenience. But results depend on planning, compliance, and clinician oversight.
At East River Dental, we don’t offer Invisalign as a cosmetic add-on. We treat it as an orthodontic system that must be applied judiciously, monitored carefully, and supported by patient cooperation.
