How Invisalign Works


  • Clear aligners are virtually invisible

  • Smooth comfortable plastic aligners

  • Aligners are removable foreasy cleaning

  • Eat whatever you want

Invisalign® takes a modern approach to straightening teeth, using a custom-made series of aligners only created for you. These aligner trays are made of smooth, comfortable and virtually invisible plastic that you wear over your teeth. Wearing the aligners will gradually and gently shift your teeth into place, based on the exact movements your dentist plans out for you. There are no metal brackets to attach and no wires to tighten. You just pop in a new set of aligners approximately every two weeks, until your treatment is complete. You’ll achieve a great smile with little interference in your daily life. The best part about the whole process is that most people won't even know you're straightening your teeth.

Treatment Process

1. Talk to an Invisalign provider

Your treatment begins after you select the experienced Invisalign-trained Provider that you feel most comfortable with and schedule your initial consultation. During the consultation, you and your doctor will discuss your case in detail to determine if you're a good candidate for Invisalign.

2. A Customized Treatment Plan is Created for You

Your doctor will take x-rays, pictures and impressions of your teeth which will be used to create a digital 3-D image. From these images your doctor will map out a precise treatment plan and show you a virtual representation of how your teeth will move with each stage of treatment. 

3. Receive Your Customized Aligners

Based on your individual treatment plan, a series of custom-made, clear aligners is then created specifically for you. Simply wear them throughout the day, and remove them when you eat or to brush and floss your teeth. As you wear each set of aligners, your teeth gently and gradually begin to shift into place.

4. Wear a New Aligner Every Two Weeks

Every two weeks, you will begin wearing a new set of aligners. For best results and a timely outcome, you should wear your aligners for 20 to 22 hours per day, throughout your entire treatment. At every stage, you will be able to see how much closer you are to having the smile that reflects the real you.

invisalign treatable case


Underbite can occur when the lower teeth protrude past the front teeth. It's usually caused by undergrowth of the upper jaw, overgrowth of the lower jaw, or both. It can also be caused by missing upper teeth. This can prevent the normal function of front teeth or molars, which can lead to tooth wear. It can also cause painful jaw and joint problems.

invisalign treatable case


Crossbite can occur when the upper and lower jaws are both misaligned. It causes one or more upper teeth to bite on the inside of the lower teeth, and can happen on both the front and the sides of the mouth. This can cause wear of the teeth, gum disease and bone loss.

invisalign treatable case


What people commonly refer to as an "overbite" is known to dental professionals as "overjet." It occurs when the upper teeth bite over the lower teeth. It's typically caused by genetics, bad oral habits, or overdevelopment of the bone that supports the teeth. This can lead to gum problems or irritation, and/or wear on the lower teeth, and can cause painful jaw and joint problems.

invisalign treatable case


Gaps between teeth can occur with abnormal continued growth of the jawbone. Missing teeth can also cause the surrounding teeth to shift due to the extra space, creating gaps in your teeth. Spacing issues and gaps between teeth can lead to gum problems (due to lack of protection by the teeth), periodontal pockets and increased risk of periodontal disease.

invisalign treatable case


Teeth crowding occurs when there is simply a lack of room within your jaw for all of your teeth to fit normally. When left untreated, overly crowded teeth can get worse over time, and result in severely crooked teeth. This crowding can lead to plaque accumulation, tooth decay and an increased chance of gum disease.

invisalign treatable case


Open bite often occurs when some teeth are unable to make physical contact with the opposing teeth for a proper bite. Most often caused by a genetic abnormal jaw structure or excessive thumb-sucking, an open bite can cause poor or painful chewing, and even speech impairment. It can also lead to greater issues like thermo-mandibular joint disorder (TMJ).

Dentists and Team
  • Dr Yong Lu, as an Elite Preferred Provider awarded by Invisalign, applies his plenty of 6-year experience of Invisalign treatment accumulated from  hundreds of successful cases, to provide solid technical assurance.

  • Dentists and the supporting staff strictly comply with the Canadian professional standard and thrive to offer satisfactory service.

Invisalign Cost

The cost of Invisalign in GTA area depends on some factors, including the amount of crowding or spacing, severity of the malocclusion, the length of treatment, the experience of the dentist, and what is included in your treatment plan. Keep in mind that if your insurance covers braces, Invisalign is also covered. A consultation is required to determine your personalized treatment and case fee.

Successful Stories

What are aligners made of, and what do they look like?

  • The virtually invisible aligners, which are made of a thermoplastic material uniquely developed for the Invisalign treatment plan, look similar to teeth-whitening trays. A series of Invisalign aligners are custom-made for you, to move your teeth in the sequence determined by your doctor.


How will Invisalign effectively move my teeth?

  • Through the use of our patented thermoplastic design, Invisalign aligners move your teeth through the appropriate placement of controlled force. The main difference is that Invisalign not only controls the force, but also the timing of the force application. During each stage, only certain teeth are allowed to move. These movements are determined by your doctor as he or she maps out your unique Invisalign treatment plan.
