Invisalign treatment FAQ

Invisalign vs. other treatment
Could Invisalign treatment be right for me?
Invisalign treatment can be a great solution for adult, teens and children looking for a virtually invisible method to improve their smile. Our innovations and technological advancements make it possible to fix nearly all common teeth-straightening and bite issues, from simple to complex — all without interrupting your busy life. And, thanks to a discreet blue dot on the outside of teen aligners, parents can be sure their child is wearing their clear aligners enough. 
What is the treatment process?

Invisalign treatment starts with a consultation with an Invisalign-trained doctor. Your Invisalign Doctor will evaluate your smile and then map out a precise, customised digital treatment plan that showcases the step-by-step transformation of your smile. 

Once you approve your plan, your unique aligners will be created. You will wear each set of aligners for 20 to 22 hours a day, changing to a new set of aligners every 1 to 2 weeks, as directed by your Invisalign Doctor. Each set of aligners will gently and gradually shift your teeth into place, according to your treatment plan, towards your beautiful new smile.

What should I bring to my consultation with my doctor?
Bring your questions (we’ve got a list to get you started here). You should also bring any information you might have about your dental history. 
What should I expect during my consultation?

During your consultation, your Invisalign Doctor will discuss your teeth-straightening goals with you and examine your smile in order to determine your specific needs. Your Invisalign Doctor may also talk to you about how quickly you could reach your new smile, as well as your individual treatment cost

Your Invisalign Doctor will most likely recommend scheduling a dental check-up and cleaning before you begin Invisalign treatment, to make sure your teeth and gums are in top health and to avoid unnecessary risks. 

They may also take x-rays as part of your treatment planning.

How long will treatment take?
The length of treatment depends on multiple factors, like how complex your case is and how often you wear your aligners.Your Invisalign Doctor will determine exactly how long your treatment could take based on your specific needs, but you could start seeing changes in as little as 6 months1.
How often will I change my Invisalign aligners?
Your Invisalign Doctor will tell you how often you should change to new Invisalign aligners (this can vary based on your individual treatment plan). Many Invisalign Doctors recommend changing Invisalign clear aligners weekly or every other week. 
How many hours per day should I wear my Invisalign aligners?
For the best results, wear your Invisalign clear aligners 20 to 22 hours a day, taking them out just for eating, drinking, brushing, and flossing. 
How often will I have appointments with my Invisalign Doctor?
Your Invisalign Doctor will schedule regular appointments, usually about once every four to six weeks or as clinically required. The goal of these visits is to ensure your Invisalign treatment is progressing as planned. 
My Invisalign Doctor mentioned "attachments." What are they and why would I need them for my Invisalign treatment?

Your Invisalign treatment may require SmartForce attachments, small tooth-coloured shapes that are attached to your teeth. 

These shapes serve as handles, giving the aligners something to gently push on in order to move your teeth with the right amount of force, and are what make complex tooth movements possible without braces. Invisalign clear aligners fit smoothly and tightly around them, so they’re barely noticeable. 

While not everyone who uses Invisalign clear aligners will need SmartForce attachments, if you need them, your Invisalign Doctor will attach them to your teeth at the start of or during your treatment and remove them when they are no longer needed. 

About Invisalign-trained doctors
What is the difference between a general dentist and a specialist orthodontist?
Specific training is required to provide Invisalign treatment, and both Invisalign-trained dentists and specialist orthodontists have completed this training. The difference is that an orthodontist is a dental specialist who has spent 3 or more additional years in an advanced, intensive educational program and only practices orthodontics. A general dentist performs general dentistry including but not limited to check-ups, cleanings and fillings. Some dentists also practice orthodontics.
Do I need a referral to see an orthodontist?
You don’t need a referral to go to an orthodontist, but sometimes your dentist may give you one if they think you need specialist orthodontic treatment. Similarly, an orthodontist may refer you to a dentist if you need general dental work or a tooth extraction to complement the orthodontic work.
What is the relationship between Invisalign aligners and my doctor?
When a doctor decides to provide Invisalign treatment, they undergo Invisalign training. The Invisalign provider training course is offered to those who have their dental practitioner qualification certificate and want to provide Invisalign treatment. This training is not a certification or warranty of a practitioner’s dental license or an endorsement of a practitioner’s dental or orthodontic skills. Once a practitioner completes the Invisalign provider training course, they can provide Invisalign treatment. However, the practitioner remains fully in control of, and responsible for, their treatment decisions. This includes designing a suitable treatment plan (including the predicted tooth movements) and prescribing a series of customised Invisalign aligners specifically to match a particular patient’s treatment plan.
What does it mean by "Invisalign Platinum" providers?
The Invisalign volume-based tier designations (e.g. Platinum Elite (PE), Platinum (P), Diamond (D) and Black Diamond (BD) are based on the number of historical Invisalign cases that a provider has submitted over a defined period of time. The tier system does not represent a doctor’s clinical experience or clinical skills in orthodontic treatment. The Invisalign provider tier level designations are not recognised as specialty areas by any applicable dental associations and have no relevance to a practitioner’s dental or orthodontic skill, or a particular treatment outcome. An Invisalign provider’s Invisalign volume-based tier designation is simply a tool that a patient can use for considering a practitioner’s experience with Invisalign treatment. You should always make your own judgement in selecting a practice and provider to start your Invisalign treatment. It should also be noted that the clinical outcome from Invisalign treatment to is based on a lot of different factors that can include the condition of your teeth, compliance, the treatment plan, and the doctor’s orthodontic experience.
If I move or switch doctors, what happens to the fee that was paid to the original doctor?
Since Invisalign treatment is customised to you, pricing and terms are set by each doctor. As you change doctors, you will need to settle your account with your current doctor and let them know you would like to make a change. Be sure to ask the new clinic what to expect when you are in treatment. If you’re about to start treatment, but think it’s likely you may have to switch doctors (for example, if you’re moving homes or in the military), coming to an agreement up front with your doctor regarding costs and payment schedules is a good idea.
How do I find an Invisalign provider?

Treatment Information & Duration
How long will treatment take?
The length of your treatment will depend on your specific needs and will be determined by your Invisalign-trained doctor. Some Invisalign treatments can be completed in as little as 4 months, but depending on the complexity of your case your Invisalign treatment could take longer, with treatment times often ranging between 12 and 18 months. 
Do I need to wear my aligners all day?
You should wear each aligner for 20 to 22 hours a day during your treatment for best results and a timely outcome.
How often do I need to see my doctor during Invisalign treatment?
You will visit your Invisalign-trained doctor for a check-up approximately every 6-8 weeks or as clinically required to see how your treatment is progressing. During your check-ups, your Invisalign-trained doctor will check that the aligners are fitting well and make any adjustments if necessary.
Can I get all my aligners at once?
You’ll be provided with enough aligners to last between visits to your doctor (usually 3-4 sets at a time). Your doctor will review your progress every 6-8 weeks or as clinically required and new aligners will be given to you at these appointments. It’s best to speak to your doctor about how many aligners you will be provided with between visits.
How do I store my Invisalign aligners when I'm not wearing them?

In most cases, one aligner case is included in your patient starter kit.

Patients who are being treated with mandibular advancement will receive two aligner cases as part of their patient starter kit.

How often should I change my aligners?
You will usually change your aligners every 2 weeks. However, please follow your Invisalign-trained doctor’s specific instructions regarding when you need to change your aligners as this may vary between patients.
How much does Invisalign treatment cost?
Costs vary from doctor to doctor and may be dependent on the complexity of your case and your course of treatment. Please speak to an Invisalign-trained doctor to get a more accurate cost estimate of your treatment. For more information about how much Invisalign treatment will cost, try our cost calculator.
Will the check-ups include a consultation fee?
Consultation fees vary from doctor to doctor. Some may offer free initial assessment while other may charge a fee. It’s best to check with an Invisalign-trained doctor for further details regarding fees. Find out more information about the cost of Invisalign treatment.
Does my doctor offer payment plans for Invisalign treatment?
Individual treating doctors may offer differing payment plans that may not require the full amount to be paid up front. Please ask your Invisalign-trained doctor for his or her payment policy. You can find out more information about how much Invisalign treatment might cost you by using our cost calculator.
Is there a price reduction if I only need the top (or bottom) aligner?
The cost for Invisalign treatment is based upon the consultation needed, is patient specific and will also depend on the Invisalign treatment needed. Your Invisalign-trained doctor will be able to provide a more accurate price guideline.
Does my health insurance cover Invisalign treatment?
If your insurance policy has orthodontic coverage, Invisalign treatment could be covered to a similar extent as conventional braces. However, as medical benefits differ significantly from policy to policy, it’ll be safer to check with your health insurance provider. Find out more information about how much Invisalign treatment will cost.
Is Invisalign treatment more expensive than metal braces?
Costs vary from doctor to doctor and may be dependent on the complexity of your case and your course of treatment. However, the cost of Invisalign treatment may be comparative to that of other alignment procedures. Please speak to your doctor about the comparative cost of treatment. You may also want to consider other treatment-related factors like effectiveness, aesthetics during treatment, duration of treatment, comfort and convenience, to determine the most appropriate treatment for you.
Things to know about Invisalign treatment
Do I need to wear my aligners all day?
You should wear each aligner for 20 to 22 hours a day during your treatment for best results and a timely outcome.
Are there restrictions on what I can eat while on treatment?
No, you can usually eat what you want while in treatment because the Invisalign aligners are removed when eating or drinking. Thus, there’s no need to refrain from your favourite foods and drinks unless instructed by your doctor. However, it’s recommended that you floss and brush your teeth after each meal and prior to re-inserting your aligners to maintain proper oral hygiene.
Can I drink hot or cold beverages while wearing my aligners?
Except for cool water, we recommend that you don’t drink while wearing the aligners. This is to avoid cavities and stains forming on your teeth, or warping your aligners with hot beverages.
Can I drink alcohol while wearing the aligners?
You should remove your aligners to consume anything except for water. Leaving aligners on while drinking may stain them and you may risk developing tooth decay while consuming fluids with sugar in them.
Can I smoke while wearing the aligners?
We don’t encourage smoking while wearing aligners because it’s possible for them to become discoloured.
Can I chew gum while wearing the aligners?
You should not chew gum while wearing your aligners as the gum may stick to the aligners. We recommend removing your aligners for all meals and snacks, including chewing gum.
Can the aligners slip off while I'm sleeping?
It’s very unlikely that your aligners will ever fall out, no matter what you’re doing at the time (whether it’s sleeping, talking or laughing). Invisalign aligners are designed to fit firmly on the teeth so this should not be a cause for concern.
Will wearing the aligners affect my speech?
Similar to other orthodontic treatments, the Invisalign aligners may temporarily affect the speech of some people for a day or two. However, as your tongue gets used to having aligners in your mouth, any misarticulation or minor speech impediment caused by the aligners should disappear. Please speak to your doctor about ways to help you get used to your aligners more quickly.
If I feel that my teeth look straight enough, can I stop the treatment?
It’s important that you follow the treatment plan developed by your doctor to ensure the best outcome. Your doctor will determine the recommended treatment duration for you depending on several considerations, including the spacing between your teeth and the need for retention.
I am moving to a different country. How can I continue my treatment?
Invisalign treatment is available in more than 100 countries worldwide, and you can transfer your Invisalign treatment to another Invisalign-trained doctor to continue your treatment. Please speak to your current Invisalign-trained doctor about the process.
Can I wear aligners if I'm pregnant?
The aligners are made of non-toxic, medical-grade plastic and can be worn during pregnancy. If you’re concerned, please consult your healthcare professional.
Is Invisalign treatment painful?
While Invisalign treatment may move your teeth without the pain and anxiety of other straightening methods, some people might experience temporary, minor 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's a sign that the Invisalign aligners are sequentially moving your teeth to their final positions. This discomfort usually goes away a couple of days after you insert the new aligner in the series.
I am experiencing pain and discomfort while using my aligners. What should I do?
If you notice a sharp pain or have significant discomfort, stop using the aligners and contact your Invisalign-trained doctor.
Are there any warnings or contraindications with the use of Invisalign aligners?


Invisalign treatment is contraindicated in patients with active periodontal disease. If you have periodontal (gum) disease, you should consult your doctor before undergoing Invisalign treatment.

Warnings with Invisalign treatment include:

In rare instances, some patients may be allergic to the aligner material. If this occurs, discontinue use and speak to a healthcare professional immediately.

In rare instances, patients with hereditary angioedema (HAE), a genetic disorder, may experience rapid local swelling of tissues including the larynx. This may be triggered by mild stimuli including dental procedures. If this occurs, discontinue use and speak to a healthcare professional immediately.

Orthodontic appliances, or parts thereof, may be accidentally swallowed or inhaled.


If I'm travelling, can I get additional aligners at my appointment with the doctor?
It’s recommended to visit your doctor for regular visits to make sure your treatment plan is on track. If you need additional aligners due to travel periods, speak to your doctor as this is dependent on your specific case and treatment plan.
My attachments have turned yellow. What can I do?
Please speak with your doctor, as he or she may need to fully remove the stained attachments and replace them.
Why do some of my aligners have bumps or ridges on them?
Depending on your specific treatment, some of the movements may require either “attachments” or “ridges” to help the aligner grip the teeth. These bumps or wells are where the aligner grips the attachment the doctor places on your teeth. The attachments are actually small pieces of composite the doctor affixes to your teeth that are then gripped by bumps on your aligners. The ridges are slim indentations in your aligners. Your Invisalign-trained doctor will use one or both of these features to achieved the desired movement.
Are the aligners really invisible?
Aligners are virtually invisible and discreet, so most people will not even notice that you’re wearing them.
