Invisalign FAQs

What is Invisalign?

Invisalign is the invisible way to straighten teeth without braces. Invisalign uses a series of clear, removable aligners to gradually straighten teeth, without metal or wires.

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, clear "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 position is achieved.

What are the primary benefits of Invisalign?

Invisalign is clear. You can straighten your teeth without anyone knowing.
Invisalign is removable. Unlike braces, you can eat and drink what you want during treatment. You can also brush and floss normally to maintain good oral hygiene. Invisalign is comfortable. There are no metal brackets or wires as with braces to cause mouth irritation, and no metal or wires means you spend less time in the doctor's chair getting adjustments. Invisalign allows you to view your own virtual treatment plan before you start—so you can see how your straight teeth will look when your treatment is complete.

What are aligners made of?

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

What do aligners look like?

Aligners are clear and look similar to tooth-whitening trays, but are custom-made for a better fit to move teeth. Some orthodontists and dentists have referred to them as "contact lenses for teeth."

Will smoking stain the aligners?

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

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.

How often must I wear my aligners?

Aligners should be worn all day, except when eating, brushing and flossing.

Is this a new way to straighten teeth?

For years, orthodontists and dentists have used removable appliances for limited treatment. Today, with the application of computer technology and custom manufacturing, Invisalign treats a broader range of cases with greater precision.

How does Invisalign effectively move teeth?

Like brackets and arch wires are to braces, Invisalign aligners move 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. At each stage, only certain teeth are allowed to move, and these movements are determined by the orthodontic treatment plan for that particular stage. This results in an efficient force delivery system.


Will the treatment be painful?

Most people experience temporary discomfort for a few days at the beginning of each new stage of treatment. This is normal and is typically described as a feeling of pressure. It is a sign that Invisalign® is working—sequentially moving your teeth to their final destination. This discomfort typically goes away a couple of days after you insert the new aligner in the series.

Will wearing Invisalign aligners affect my speech?

Like all orthodontic treatments, aligners may temporarily affect the speech of some people, and you may have a slight lisp for a day or two. However, as your tongue gets used to having aligners in your mouth, any lisp caused by the aligners should disappear.

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

No. Unlike traditional wires and brackets, you can eat whatever you desire while in treatment because you remove your aligners to eat and drink. Thus, there is no need to restrict your consumption of any of your favorite foods and snacks, unless instructed otherwise by your doctor. Also, it is important that you brush your teeth after each meal and prior to re-inserting your aligners to maintain proper hygiene.
