Align Your Smile
You want straighter teeth, but the idea of metal brackets and wires feels like a lot. That’s where Shin Dentistry comes in. We offer Invisalign, a teeth-straightening orthodontic treatment that uses a series of clear, removable aligners instead of traditional braces.
Invisalign is a clear aligner system that gradually shifts your teeth using custom-fitted trays made from smooth, medical-grade plastic. If you’ve been curious about how it works, what it can treat, or whether habits like smoking affect your results, here’s what you need to know.
How Invisalign Works
The process starts with a 3D digital scan of your mouth. No messy moulds, just a quick and comfortable scan that maps out exactly where your teeth are and where they need to go. From there, we’ll build a custom treatment plan.
You wear each set of aligners for about 1–2 weeks before switching to the next set. Each new set moves your teeth a little further along. Over time, these small shifts add up to a noticeably straighter smile.
Invisalign aligners must be worn 20 to 22 hours per day in order to deliver consistent results.
What Is Invisalign Made From?
The aligners are made from a BPA-free thermoplastic material. It’s flexible enough to fit snugly over your teeth and smooth enough that most people barely notice them once they’re in. There are no sharp edges or brackets that can rub against the inside of your mouth.
How Long Treatment Takes
Most people complete treatment in somewhere between 12 and 18 months. That timeline can change depending on how much movement your teeth need and how consistently you wear your aligners. More complex cases take longer, while minor adjustments can move faster.
What Invisalign Can Treat
Invisalign works well for a range of alignment concerns. These include:
- Crowded or widely spaced teeth
- Mild to moderate overbite, underbite, or crossbite
- Open bites and gap teeth
Who Is a Good Candidate
Teens and adults with mild to moderate alignment issues are often good fits for Invisalign. The bigger factor is commitment. You need to wear your aligners for 20 to 22 hours every day, or else the treatment won’t work properly. A consultation with your dental team can confirm whether clear aligners are the right fit for your specific situation.

The Pros & Cons of Invisalign
What Works in Your Favour
One of the biggest draws is that the aligners come out. You take them off to eat, to drink anything other than water, and to brush your teeth. There’s no worrying about food getting caught in brackets. Plus, since the trays are clear, most people won’t even notice you’re wearing them.
Factors to Keep in Mind
However, Invisalign isn’t the right fit for every situation. Severe bite issues or significant tooth movement may require a different approach. Your aligners can also be lost or damaged if you’re not careful about where you put them when they’re out. Make sure that you always store them in their case.
Can You Smoke With Invisalign?
This is a question that comes up often, and the straightforward answer is that smoking while your aligners are in can cause problems. The heat from smoking can warp the plastic material, which changes how the aligner fits. A poor fit means your teeth aren’t being shifted the way they should be.
Beyond the warping, smoke causes visible staining and discolouration of the aligner trays. The whole point of clear aligners is that they’re discreet, so stained trays are much easier for others to notice. Smoking also contributes to other oral health concerns, as does vaping.
How Smoking Affects Your Results
Some people try to work around the issue by removing their aligners before smoking. That avoids the staining and warping, but it creates a different problem.
Every minute your aligners are out counts against your daily wear time. You need 20 to 22 hours of wear per day for your treatment to progress properly. Frequent smoking breaks can chip away at that time, and less wear time means slower results.
What to Expect at Your Invisalign Appointment
At your first Invisalign appointment, a digital scan is taken of your teeth. Your dentist will review your treatment plan with you and let you know how long the process will take. There’s no need to take impressions or moulds of your teeth.
Keeping Your Aligners & Teeth Clean
Rinse your aligners with lukewarm water, not hot. Hot water can distort the shape of the trays. Before you put your aligners back in, brush and floss your teeth, as trapping food or bacteria under the trays can work against your oral health.
