Imagine straighter teeth and a better bite pattern, without having to wear braces—even if you’re over 21.  It's possible for Alberta Invisalign patients! This system is so discreet, most people won’t even know you’re undergoing orthodontic treatment.


Patients receiving Invisalign in Westlock begin with a series of clear, smooth, plastic aligners that fit comfortably over your teeth. Every two weeks, the aligners are changed. Each aligner is custom made with precise designs, to steadily and gradually guide your teeth into an ideal placement. Because they are customized specifically for your teeth, they remain comfortable and secure in your mouth. Your Invisalign system is crafted specifically for your Leigh Smile Center treatment plan, resulting in a more functional, straighter, and more pleasing smile. Many adults find that Invisalign could be a great choice for them, depending on their unique case and treatment plan.

First introduced to the market in 1999, Invisalign was developed by an adult orthodontics patient who came up with the theory that if his dental retainer could make his teeth move in small increments, then a series of successive retainers could combine to effect large-scale repositioning of the teeth. Since then, treatment with Invisalign has proven to be a popular option for people in Alberta seeking a discreet way to obtain a straighter smile.

Invisalign can be used to treat many orthodontic issues:

·         Overly crowded teeth

·         Widely spaced teeth

·         Crossbite

·         Overbite

·         Underbite


The treatment plan starts with a Free consultation with Dr. Nicholas Teoh at the Leigh Smile Center office in Westlock, Alberta to determine if Invisalign is the best choice for you. Then, x-rays and impressions of the teeth are taken and sent to Invisalign, where they will be used to create a 3D digital image. From that point, a precise treatment plan and series of aligners are developed to guide your teeth into an optimal position.

Treatment with Invisalign is simple. You can remove your aligners when eating, allowing you to continue to enjoy your favorite foods. When removed, they also allow you unimpeded access to your teeth when brushing or flossing, resulting in continued good oral health. The aligners can be cleaned using Invisalign cleaner, or can simply be brushed and rinsed.

For best results, the aligners should be worn at least 22 hours every day. Removing them for long periods will extend the amount of time needed for treatment. If participating in sports where protective mouth gear is required, simply remove the Invisalign aligner, store it safely, and then re-insert it as soon as possible. The procedures and protocols can all be explained to you at the Leigh Smile Center.

Want to know if Invisalign is right for you? Dr. Wong, Dr. Teoh and the team at THE LEIGH SMILE CENTER in WESTLOCK are happy to meet with you. Remember, it doesn’t cost anything for a second opinion at Leigh Smile Center, and you do not need a referral from your General Dentist!
