Clear aligner treatment at Red Rose Dentistry typically takes 6 to 18 months, depending on the complexity of your case. Simple crowding or spacing issues can be corrected in as little as 6 months; complex bite corrections may take up to 18–24 months. Here is everything you need to know about treatment timelines before your free consultation.

Invisalign vs. ClearCorrect — Does It Affect Treatment Time?
Red Rose Dentistry uses ClearCorrect as its primary clear aligner system — Dr. Firas Khakani is a recognized ClearCorrect Key Opinion Leader for North America (2025). ClearCorrect and Invisalign use the same core technology (custom 3D-printed aligner trays worn in sequence) and achieve virtually identical treatment timelines for equivalent cases.
The more important factor than brand is your provider’s experience in planning the case. An expert planner can often reduce treatment time compared to a generic setup, regardless of which system is used.
How Long Does Treatment Take? Timeline by Case Type
| Case Complexity | Examples | Estimated Timeline |
|---|---|---|
| Mild | Minor crowding, small gaps, 1–2 teeth to straighten | 6 – 10 months |
| Moderate | Multiple crowded teeth, moderate spacing, mild overbite | 10 – 15 months |
| Moderate-complex | Significant crowding, noticeable overbite/underbite, multiple arches | 15 – 18 months |
| Complex | Severe bite issues, crossbite, significant rotation corrections | 18 – 24 months |
| Teen treatment | Varies by growth stage and compliance | 12 – 24 months |
Note: These are averages. Your exact timeline is determined at your free consultation, after we take digital X-rays and photos and map your specific tooth positions. We give you a concrete number — not a range — before you commit.
What Factors Affect How Long Clear Aligner Treatment Takes?
1. Complexity of Your Case
The single biggest factor. Simple cases (one or two teeth out of position) may complete in under 6 months. Complex cases involving significant bite correction, severe crowding, or multiple planes of movement take longer — and require more aligner stages to move teeth safely.
2. How Many Hours Per Day You Wear Your Aligners
Clear aligners require 20–22 hours of wear per day for treatment to progress on schedule. Every hour the aligners are out, the teeth are not moving. Patients who consistently under-wear their trays extend their own treatment — sometimes by months. This is the #1 patient-controlled factor.
3. How Quickly You Advance Between Trays
Standard aligner progression is 1 new tray every 7–10 days (ClearCorrect) or every 7–14 days (Invisalign). Wearing each tray for the full recommended duration before switching ensures teeth have reached their target position before the next movement begins. Rushing can cause fit problems and require refinements.
4. Refinements
At the end of your planned tray sequence, some teeth may need additional small movements called refinements. We take new scans, design additional trays, and continue until the final result matches the plan. Refinements are included in your treatment at Red Rose Dentistry at no extra charge and typically add 4–12 weeks.
5. Your Age
Teens and younger adults typically experience slightly faster tooth movement than patients over 40, because bone density is lower and teeth respond more readily. That said, we treat adults at all ages — treatment still works effectively, it may just take marginally longer in complex cases.
How to Make Your Clear Aligner Treatment Go Faster
- Wear your aligners 22 hours a day, every day — only remove them to eat, drink (anything other than water), and brush/floss
- Switch trays on schedule — don’t delay tray changes “because they still feel tight.” Mild tightness is normal and expected
- Keep all scheduled check-in appointments — we monitor progress and catch fit issues early before they delay treatment
- Use chewies — small aligner-seating tools that help trays fit snugly against teeth, improving tooth contact and movement efficiency
- Avoid excessive chewy or sticky foods — these don’t affect aligners directly (since you remove them to eat), but food debris left after eating can damage trays if you reinsert them without rinsing
What Happens After Active Treatment? (Retainer Phase)
Once your final aligner tray is complete, your teeth need to be held in their new positions with retainers. Teeth have a natural tendency to drift back (“relapse”) — especially in the first year after treatment.
Typical retainer schedule after clear aligner treatment:
- First 6 months: Retainers worn full-time (22+ hours/day), same wear schedule as aligners
- Months 6–12: Nights only
- Long-term: Ongoing nights-only wear indefinitely — or as directed by your provider
Red Rose Dentistry provides custom Essix (clear) retainers and Hawley retainers, with a monitoring schedule to protect your investment long-term. We also offer permanent lingual (bonded) retainers for patients who prefer a maintenance-free option.
Frequently Asked Questions — Clear Aligner Timeline in Hamilton
Q: Can I get clear aligners that finish in 3 months?
A: Very few cases genuinely complete in 3 months — typically only patients with a single tooth that needs minor rotation. “Fast” aligner programs marketed at 3–6 months often only address front teeth cosmetically and do not correct bite issues. We show you exactly what your treatment covers before you start.
Q: How is treatment time different for teens vs. adults?
A: Teen treatment tends to go slightly faster for straightforward cases due to more responsive bone. However, teens are also more likely to under-wear aligners — which negates the biological advantage. ClearCorrect offers a compliance indicator dot on each tray for teen cases so parents can verify wear time.
Q: Do I need to take time off work for clear aligner treatment?
A: No. Clear aligner check-in appointments are brief (15–30 minutes) and typically every 8–12 weeks. Most patients have no activity restrictions throughout treatment.
Q: What if I lose an aligner tray during treatment?
A: Contact us immediately. We can often have you wear the previous tray while a replacement is ordered. Replacements typically arrive within 1–2 weeks. Losing trays does not end treatment, but it can add time and cost if it happens repeatedly.
Q: Is ClearCorrect faster than braces?
A: For mild to moderate cases, ClearCorrect is often equivalent to or slightly faster than braces. For complex cases (severe crowding, significant bite correction), braces may be more efficient because they give the orthodontist more precise mechanical control. We’ll tell you honestly which is better for your specific case at your free consultation.
