Why choose Invisalign clear aligners?

Invisalign is the world's most widely used clear aligner system, with over 15 million patients treated. Dr Benguira is a certified Invisalign orthodontist who also offers SPARK aligners — a cutting-edge technology with a slightly clearer, more stain-resistant material.

Why offer both? Because every smile is unique. Some cases respond better to Invisalign, others to SPARK. As a specialist orthodontist (not a general dentist), Dr Benguira selects the optimal technology for your specific case.

Invisalign vs SPARK — Two technologies, one goal

Feature	Invisalign	SPARK

Dr Benguira evaluates your case and recommends the technology best suited to your needs.

✓ Management of complex cases (surgery, anchorage, extractions)
✓ Access to both technologies (Invisalign AND SPARK) to choose the best
✓ 15 years of experience at CHU Sainte-Justine

Frequently asked questions about Invisalign

What is the difference between Invisalign and SPARK?

Both are clinically equivalent clear aligner systems. Invisalign is the market pioneer with over 15 million patients treated. SPARK uses TruGEN material, which is slightly clearer and more stain-resistant. Dr Benguira is certified in both technologies and chooses the optimal system for each patient.

How much does Invisalign treatment cost?

The cost varies depending on case complexity, generally between $3,900 and $10,000. The exact price will be determined following a personalized consultation. Flexible financing is available with monthly payments tailored to your budget. The consultation is free and includes a precise estimate for your case.

How long does treatment take?

12 to 24 months on average. Simple cases (minor crowding, small gaps) can take 6 to 10 months. More complex cases can take up to 30 months. Dr Benguira gives you a precise estimate at the consultation.

Do aligners hurt?

You'll feel pressure, not pain. The first few days with new aligners, a tightness sensation is normal — a sign that your teeth are moving. The discomfort is generally less than with traditional braces.

Can I eat and drink whatever I want?

Yes! Simply remove the aligners to eat and drink (except water). Unlike braces, there are no food restrictions. Popcorn, apples, caramel — everything is allowed.

Does Invisalign work for teenagers?

Absolutely. Invisalign and SPARK offer versions specifically designed for teenagers, with wear indicators and features adapted to growth. It's an excellent option for motivated teens who prefer a discreet solution.

My dentist also offers Invisalign. Why see an orthodontist?

An orthodontist has completed 3 additional years of specialization after dental school. Dr Benguira is FRCD(C) certified and has treated over 500 aligner cases. He can manage complex cases, offer both technologies (Invisalign and SPARK), and ensure an optimal result.
