Invisalign in Ottawa: How Clear Aligners Work (Step-by-Step Treatment Timeline)

Mar 19, 2026

Clear aligner therapy has transformed orthodontic treatment, offering Ottawa residents a virtually invisible way to achieve straighter teeth. At Manotick Main Dental, we’ve helped countless patients from Manotick, Barrhaven, Nepean, and surrounding areas understand exactly how clear aligners work and what to expect throughout their treatment journey.

If you’re considering Invisalign or similar clear aligner systems like ClearCorrect, this comprehensive guide walks you through each phase of treatment so you can make an informed decision about your smile.

How Clear Aligners Straighten Teeth

Clear aligners are custom-made, removable trays crafted from BPA-free transparent plastic. Each set of aligners applies gentle, controlled pressure to specific teeth, gradually shifting them into proper alignment.

Unlike traditional braces that use brackets and wires to pull teeth into position, clear aligners push teeth using precise 3D computer modeling. This technology maps out your entire treatment from start to finish before you even begin wearing your first aligner.

Your Step-by-Step Treatment Timeline

Step 1: Initial Consultation (Week 1)

Your journey begins with a comprehensive consultation at our Manotick dental clinic. During this appointment, our team will assess your teeth and bite, take digital x-rays, and discuss your smile goals.

We’ll determine whether clear aligners are appropriate for your case. Clear aligner therapy effectively treats many orthodontic conditions including crowding, spacing, overbites, underbites, and crossbites. This is also when we discuss payment options and answer any questions you have about the process.

Step 2: Digital Impressions and Treatment Planning (Week 2)

Once you decide to proceed, we capture detailed digital impressions of your teeth. These impressions, along with photographs and x-rays, are sent to the aligner laboratory where technicians use advanced 3D imaging software to create your personalized treatment plan.

The treatment plan shows a virtual representation of how your teeth will move at each stage. You’ll actually see a preview of your future smile before treatment begins. Our team reviews this plan carefully and communicates with the lab to ensure every detail is correct.

Step 3: Receiving Your Custom Aligners (Weeks 3-4)

Your custom aligners typically arrive within two to four weeks. At your fitting appointment, we’ll ensure they fit properly and provide detailed instructions on how to wear and care for them.

Key points covered during this appointment include wearing aligners 20-22 hours daily, removing them only to eat and brush, proper cleaning techniques to keep aligners clear and odour-free, and what to do if you lose or damage an aligner.

Step 4: Active Treatment Phase (6-18 Months)

The active treatment phase is where transformation happens. You’ll wear each set of aligners for approximately two weeks before switching to the next set in the series. Each aligner makes small, incremental adjustments—usually about 0.25mm of movement per aligner.

What to expect during this phase:

Initial adjustment period: The first few days with new aligners may cause mild pressure or discomfort. This is normal and indicates the aligners are working.

Regular check-ups: You’ll visit our office every two to six weeks so we can monitor progress and provide your next sets of aligners.

Attachments: Some patients need small tooth-coloured attachments bonded to certain teeth. These provide extra grip for the aligners to make more complex movements.

Elastics: For bite correction, you may use small rubber bands with your aligners.

Step 5: Refinement (If Needed)

After completing your initial set of aligners, most patients need minor refinements. This involves taking new impressions and receiving additional aligners to perfect your results. Refinement aligners are included in your treatment cost at Manotick Main Dental.

Step 6: Retention Phase (Ongoing)

Once your teeth are perfectly aligned, retention is essential to maintain your results. Teeth naturally want to shift back to their original positions, so wearing a retainer prevents this movement.

You have options for retainers. Vivera retainers, made by the same company that produces Invisalign, look similar to your treatment aligners. Alternatively, you may opt for a traditional wire retainer. Initially, you’ll wear your retainer full-time, gradually transitioning to nighttime-only wear.

How Long Does Treatment Take?

Clear aligner treatment typically takes 6 to 18 months for adults, depending on the complexity of your case. Simple spacing or mild crowding cases may complete in as little as 6 months, while more complex bite corrections can take 18 months or longer.

Your treatment duration depends on how consistently you wear your aligners, the complexity of your orthodontic issues, your age and how your teeth respond to treatment, and whether refinements are needed.

Tips for Successful Clear Aligner Treatment

Wear your aligners consistently. The 20-22 hour daily requirement isn’t just a suggestion—it’s crucial for staying on track. Remove aligners only for eating, drinking anything other than water, and oral hygiene.

Practice excellent oral hygiene. Brush after every meal before reinserting your aligners. This prevents food particles from being trapped against your teeth, which can cause tooth decay and staining.

Clean your aligners daily. Rinse them each time you remove them and clean them with a soft toothbrush and clear antibacterial soap. Avoid hot water, which can warp the plastic.

Keep your appointments. Regular check-ins allow us to ensure your treatment is progressing as planned and address any concerns early.
