Invisalign | Frequently Asked Questions

How does Invisalign work?

Invisalign uses 3-D computer imaging technology to depict the complete treatment plan from the initial position to the final desired position from which a series of custom-made “aligners” are produced. Each aligner moves teeth incrementally and is worn for about two weeks, then replaced by the next in the series until the final desired position is achieved.

What are aligners made of?

Aligners are made of clear, strong medical grade non-toxic plastic that is virtually invisible when worn.

How long will treatment take?

The length of treatment is dependent on the severity of each individual patient’s orthodontic issues.  Treatment may vary from anywhere between six months to two years with an average treatment taking around 12 to 14 months.

How does Invisalign effectively move teeth?

Like brackets and arch wires, the Invisalign aligner moves teeth through the appropriate placement of controlled force on the teeth. The principal difference is that Invisalign not only controls forces, but also controls the timing of the force application. With each aligner, only certain teeth are allowed to move, and these movements are determined by the orthodontic treatment plan for that particular aligner. This results in an efficient force delivery system.

Will there be an initial consultation fee?

At McKeefry Dental, prior to commencing with the Invisalign approach, we hold an initial on-site consultation.  This appointment is free and usually takes just 15 minutes. 

Is there a price reduction if I only require the top/bottom aligner?

The charge for Invisalign is based upon the consultations needed and the 3-D modelling cost. Whether your treatment requires one arch or two arches (i.e. treatment to your top and bottom teeth) the price will be virtually the same. 

Are there restrictions on what I can eat while in treatment?

No. Unlike traditional orthodontics, you can usually eat whatever you desire while in treatment because you remove your aligners/dental braces to eat and drink. Thus, there is no need to restrict your consumption of any of your favourite foods and snacks, unless instructed otherwise.

Also, it is important that you brush your teeth after each meal and prior to reinserting your aligners to maintain proper hygiene.

Can I drink with aligners still on?

You should remove your aligners to drink anything else except cold water. Leaving aligners on while drinking may stain them; risk tooth decay if they drink fluids with sugar in them; and if you are drinking just clean hot water, you may warp the aligners.

Will smoking stain the aligners?

We discourage smoking while wearing aligners because it is possible for the aligners to become discoloured.

Can I chew gum while wearing aligners?

No, gum will stick to the aligners. We recommend removing your aligners for all meals and snacks.

What's the best way to clean my aligners?

The best way to clean your aligners is by brushing and rinsing them in lukewarm water. We can also supply you with aligner cleaning crystals.  You can also simply soak them in white vinegar diluted with water.

How often must I wear my aligners?

Your aligners/dental braces should be worn all day, except when eating, brushing and flossing.  It’s important that you wear each aligner for 22 hours a day as this is critical to the success of the Invisalign treatment.
