A straight smile is not just about aesthetics. Well-aligned teeth are easier to clean, less prone to cavities and gum disease, and put less strain on your jaw joints and muscles. If you are looking for an orthodontist in Montréal, Dr Lachance Dental Clinic offers modern orthodontic treatment for both teenagers and adults — from traditional metal braces to clear aligners — all from our convenient downtown location at Complexe Desjardins, steps from Place-des-Arts metro.
What does orthodontic treatment do?
Orthodontics uses controlled, gentle pressure over time to gradually move teeth into their correct positions. Treatment corrects a wide range of issues:
- Crowded teeth — teeth that overlap or have insufficient space
- Gaps and spacing — excessive space between teeth
- Overbite — upper teeth protrude too far over lower teeth
- Underbite — lower teeth sit in front of upper teeth
- Crossbite — upper and lower teeth do not align properly side-to-side
- Open bite — upper and lower teeth do not meet when the mouth is closed
- Midline misalignment — the centre lines of upper and lower teeth do not match
Beyond aesthetics, correcting these issues can reduce jaw pain (TMJ disorders), make brushing and flossing more effective, and prevent uneven tooth wear.
Orthodontic options at our Montréal clinic
Traditional metal braces
Metal braces remain the most precise and cost-effective orthodontic option for complex cases. Modern braces are significantly smaller and more comfortable than those from 20 years ago. They work continuously — you do not need to remember to wear them — and can handle virtually any degree of misalignment.
- Most effective for severe crowding, complex bite corrections, and rotations
- Typically lower cost than clear aligner systems
- Excellent results for growing teenagers
- Colour bands available for teens who want to personalize their braces
Clear aligners (Invisalign and similar systems)
Clear aligners are a series of custom-made, removable, transparent trays that progressively shift your teeth. They are nearly invisible when worn and can be removed for eating, drinking, brushing, and special occasions. This makes them especially popular among adult professionals and teenagers who are self-conscious about braces.
- Virtually invisible — most people will not notice you are wearing them
- Removable — eat whatever you want and maintain normal oral hygiene
- Comfortable — smooth plastic edges with no wires or brackets to irritate soft tissue
- Fewer emergency appointments — no broken wires or brackets
- Best for mild to moderate cases; some complex cases now treatable too
Treatment with clear aligners requires discipline: aligners must be worn 20–22 hours per day to achieve the planned movement. Read our complete guide: 5 things to know before starting orthodontic treatment.
Retainers and post-treatment maintenance
Once your active orthodontic treatment is complete, retainers are essential to maintain your new smile. Without them, teeth naturally drift back toward their original positions. We provide both fixed (bonded) and removable retainer options, and guide you on how long to wear them for lasting results.
Orthodontics for adults in Montréal — it is never too late
Many adults assume orthodontic treatment is only for teenagers. In reality, there is no upper age limit for orthodontics — as long as your gums and bones are healthy, teeth can be moved at any age. Adult orthodontic treatment has grown significantly, with clear aligners making it more discreet and convenient than ever before.
Common reasons adults seek orthodontic treatment in Montréal include:
- Teeth that have shifted after previous orthodontic treatment (never wore retainers)
- Changes in bite or alignment due to tooth loss or wear
- Wanting to improve their smile before a major life event (wedding, new job)
- Reducing jaw discomfort caused by misalignment
- Preparing for cosmetic dental work (straightening first improves results of veneers or whitening)
Orthodontics for teenagers in Montréal
The teenage years — typically 11 to 17 — are an ideal time for orthodontic treatment because the jaw is still growing and teeth move more efficiently. Early treatment (interceptive orthodontics) can sometimes begin even earlier, around ages 7–10, to guide jaw development and reduce the complexity of later treatment.
Our orthodontic team works comfortably with teenagers and makes appointments accessible around school and activity schedules. We also offer options at our downtown Montréal location that allow students from McGill, Concordia, CÉGEP and other downtown schools to come in conveniently without crossing the city.
How long does orthodontic treatment take in Montréal?
Treatment duration depends on the complexity of the case:
- Mild cases (minor spacing, slight crowding): 6–12 months
- Moderate cases (moderate crowding, small bite issues): 12–18 months
- Complex cases (severe crowding, significant bite correction): 18–30 months
Average treatment time is around 18 months. Compliance — wearing aligners as instructed or attending adjustment appointments on time — is the biggest factor in staying on schedule.

Frequently asked questions — orthodontist Montréal
At what age should my child first see an orthodontist?
The Canadian Association of Orthodontists recommends a first orthodontic evaluation around age 7, when the first permanent molars and incisors have emerged. Early evaluation does not always mean early treatment, but it allows us to monitor development and intervene at the right time if needed.
Does orthodontic treatment hurt?
There is typically some soreness for 2–5 days after braces are placed or tightened, or after switching to a new aligner tray. This is normal and manageable with over-the-counter pain relievers. Most patients adapt quickly and report the process is far more comfortable than they expected.
Can I play sports or a musical instrument with braces?
Yes to both. For contact sports, we recommend a custom mouthguard worn over your braces. Wind instrument players adapt to playing with braces within a few weeks. Clear aligners are removed for sports and instrument playing.
What happens if I do not wear my retainer after treatment?
Teeth will gradually shift back. The amount and speed of relapse varies by individual, but some movement almost always occurs without retention. Wearing retainers as instructed — typically nightly long-term — is the only way to maintain your orthodontic results for life.
Is orthodontic treatment covered by insurance in Québec?
Many private dental insurance plans include orthodontic coverage, often up to a lifetime maximum per patient. RAMQ does not cover orthodontics. We verify your coverage and submit claims on your behalf.
