Invisalign is a clinically proven orthodontic treatment that uses a series of custom-made, removable clear aligners to gradually shift teeth into their ideal position — without metal brackets or wires. Most adults and teens with mild to moderate alignment concerns are good candidates, though a licensed dentist must assess your bite, tooth spacing, and jaw structure before recommending treatment. If you have been wondering whether Invisalign could work for you, here are straightforward answers to the questions we hear most often at our Calgary NW clinic.
What Dental Issues Can Invisalign Treat?
Invisalign is effective for a wider range of conditions than many patients expect. Clear aligner technology has advanced significantly, and today’s systems can address:
- Crowded teeth — where there is insufficient arch space, causing teeth to overlap
- Gapped teeth — spaces between teeth caused by missing teeth or natural jaw growth patterns
- Overbite — where the upper front teeth overlap excessively with the lower front teeth
- Underbite — where the lower teeth sit in front of the upper teeth
- Crossbite — where upper and lower teeth don’t align properly side to side
- Open bite — where the upper and lower teeth don’t meet when the mouth is closed
Severely complex bite issues — such as significant skeletal discrepancies — may still require traditional orthodontics or a combination approach. Your dentist will be transparent about what Invisalign can and cannot achieve for your specific case.
How Does Invisalign Actually Work?
Treatment begins with a 3D digital scan of your teeth — no messy impressions required. Using this scan, your dentist maps out a precise tooth movement plan, and a series of custom aligners is fabricated. Each aligner is worn for approximately one to two weeks before moving to the next in the series, gradually guiding teeth toward the desired position.
You wear the aligners for 20 to 22 hours per day, removing them only to eat, drink anything other than water, and brush and floss your teeth. Check-in appointments are typically scheduled every six to eight weeks so your Calgary NW dentist can monitor progress and ensure your teeth are tracking correctly.
How Long Does Invisalign Treatment Take?
Treatment length varies depending on the complexity of your case. On average:
- Mild corrections may be completed in as few as six to twelve months
- Moderate cases typically require twelve to eighteen months
- More complex alignment issues can take up to twenty-four months
Consistency is the single biggest factor in staying on schedule. Patients who wear their aligners as directed tend to finish treatment on time or even ahead of projections.
Is Invisalign Comfortable — and Will Anyone Notice?
Most patients experience mild pressure or tenderness for the first day or two after switching to a new aligner — this is a normal sign that your teeth are moving. The aligners are made from smooth, BPA-free thermoplastic material, so there are no brackets or wires to irritate the gums or cheeks.
As for visibility, Invisalign aligners are virtually transparent. The vast majority of wearers report that colleagues, friends, and family members either don’t notice or only notice when they are told. Small tooth-coloured attachments (composite resin dots bonded to certain teeth) are sometimes used to help aligners grip and guide more complex movements — these are subtle and blend with your natural tooth colour.
What Does Invisalign Cost in Calgary, and Is It Covered?
Invisalign costs in Calgary vary based on the number of aligners required and overall treatment complexity. Many Alberta dental benefit plans include orthodontic coverage that applies to Invisalign, just as it would to traditional braces. Our team at Expressions Dental will review your coverage, provide a detailed treatment estimate, and discuss flexible payment options before you commit to anything.
What Happens After Treatment Is Complete?
Once your final aligner has done its job, retention is essential. Teeth have a natural tendency to shift back toward their original positions — a phenomenon called orthodontic relapse. Your dentist will fit you with a custom retainer (typically a clear removable retainer worn nightly) to hold your results long-term. Skipping retainer use is the most common reason patients see unwanted shifting after orthodontic treatment.

Frequently Asked Questions
Am I a good candidate for Invisalign in Calgary?
Most adults and teenagers with mild to moderate alignment concerns — including crowded teeth, gaps, overbites, underbites, crossbites, and open bites — are good candidates for Invisalign. A licensed dentist at Expressions Dental in Calgary NW will evaluate your bite, jaw structure, and overall oral health during a consultation to confirm whether clear aligners are the right option for you.
Does Invisalign hurt?
Invisalign is generally more comfortable than traditional metal braces, though most patients experience mild pressure or temporary tenderness for one to two days after switching to a new aligner. There are no brackets or wires to cause irritation to the gums or inner cheeks, and the smooth thermoplastic material is designed for all-day comfort.
How long does Invisalign take to straighten teeth?
Treatment length depends on the complexity of your case — mild corrections can take as little as six to twelve months, while more involved alignment issues may require up to twenty-four months. Wearing your aligners for the recommended 20 to 22 hours per day is the most important factor in keeping your treatment on schedule.
Can I eat normally with Invisalign?
Yes — one of the biggest advantages of Invisalign is that the aligners are fully removable, so you can eat and drink whatever you like without restrictions. You simply remove the aligners before meals, eat as usual, brush and floss your teeth, then replace the aligners before carrying on with your day.
Does my Alberta dental insurance cover Invisalign?
Many Alberta dental benefit plans include orthodontic coverage that applies to Invisalign treatment, just as it would to traditional braces. The team at Expressions Dental will review your specific plan, confirm your coverage, and provide a full cost estimate so there are no surprises before treatment begins.
Will people be able to tell I'm wearing Invisalign aligners?
Invisalign aligners are made from virtually transparent thermoplastic material, making them very difficult to detect during everyday conversation. Small tooth-coloured composite attachments are sometimes added to certain teeth to assist with complex movements, but these are designed to blend naturally with the colour of your teeth.
Do I need a retainer after Invisalign treatment is finished?
Yes — wearing a retainer after Invisalign is essential to maintain your results and prevent orthodontic relapse, which is the natural tendency of teeth to drift back toward their original positions. Your dentist at Expressions Dental will provide a custom clear retainer, typically worn nightly long-term, to keep your newly straightened smile in place.
