Frequently asked questions

What is Smilers®?

Smilers® transparent aligners are orthodontic appliances designed to correct the alignment of your teeth. They consist of a series of custom-made, clear, removable aligners made from impressions of your mandible and maxilla. These aligners are designed to apply gentle mechanical forces to realign your teeth. Each aligner will gradually initiate movement of your teeth thereby correcting their position.

How does treatment with invisible aligners work?

Your transparent Smilers® aligners are custom made. They are virtually invisible and perfectly fit your teeth.

Each aligner slightly moves your teeth, horizontally, vertically and even rotates them, if necessary. Your aligners are designed to use the right amount of force, in the right place, at the right time.

When you move to the next set of aligners (usually every 3 weeks), your teeth gradually move, following a personalised treatment plan developed by your dentist and Smilers® specialists.

How long does the treatment last?

Only your practitioner, with the help of the Smilers® teams creating your treatment plan, can give you an idea of its duration. Depending on your practitioner's estimation, a second phase may be needed to achieve your ideal alignment.
The average length of treatment with Smilers® is 12 months for patients undergoing standard treatment and 4 months for patients undergoing accelerated treatment. 

Who can benefit from Smilers® treatments?

Designed for teens and adults, Smilers® transparent aligners change smiles without changing lives. Teens can get straighter teeth thanks to unique treatment developed for them, while adults get the smile they always dreamed of without changing their routines.


Is the treatment painful?

Some people may experience mild temporary discomfort for a few days when using their new aligners at the beginning of each new stage of treatment. Patients usually describe a feeling of pressure, which is quite normal. This means that the treatment is working properly, and this feeling usually disappears after a few days.

Are there any side effects?

As with any treatment, wearing Smilers® clear aligners can have some bothersome effects. The main problems that may occur are (non-exhaustive list): 

  • Irritation or inflammation of the gums, cheeks or lips for a few days.
  • Dental sensitivity or feeling of pressure that may be felt for a few days when changing aligners.
  • Temporary increase salivation or dry mouth.
  • Slight change in speech, which should disappear after a few days.
  • The appearance of small white areas on the teeth (areas of demineralisation), dental cavities, periodontitis, inflammation of the gums (in case of poor dental hygiene).
  • In rare cases, problems may appear in the jaw joint, causing pain, migraines or ear problems. 
  • Painful sensations could appear due to a poor adaptation of your appliance. It is then imperative that you temporarily stop wearing your dental aligner.

How does it differ from conventional orthodontic treatment?

The main reason adult patients choose dental aligners is that they are invisible. They allow you to hide the fact that you are undergoing orthodontic treatment, which can be embarrassing. Unlike traditional orthodontic appliances, patients using Smilers® aligners also appreciate the ability to remove their clear aligners when eating and brushing their teeth. This allows them to stick to their usual brushing and dental care routines. 

How much does Smilers® cost?

How can I finance my treatment?

Some health insurance companies provide orthodontic care and/or supplement the French Social Security cover, whether you are an adult or adolescent. The amount or percentage of the cover varies from one health insurance company to another. So, if you would like more information on this subject, please do not hesitate to contact your insurer who will be able to give you an estimate, a package or a cover rate for your orthodontic treatment.

How to start the treatment?

Fix an appointment with a Smilers® dentist or orthodontist and start by your smile diagnosis.

Can I consult any practitioner to start my dental treatment?

Although Smilers® can be used by all dental practitioners, they require special training. All orthodontists and dentists who wish to treat their patients with Smilers® aligners must take a training course. More than 1,000 dentists and orthodontists worldwide are already trained to treat patients with Smilers®... and this is just the beginning.

How often do I need to visit my practitioner once I have started my orthodontic treatment?

Typically, patients visit their Smilers® practitioner every 6-8 weeks to verify that treatment is proceeding as planned and to receive new sets of Smilers® dental aligners, but the actual frequency depends on your Smilers® practitioner’s judgement.
If your treatment is accelerated, appointments are made every week for a photostimulation session.

Is the length of treatment definitive?

If the result obtained with the 1st treatment plan is not perfect, because the science of predicting tooth alignment is not an exact science, a 2nd phase may be discussed with your practitioner. This may be included in your initial offer.

Once treatment is complete, will I need a retainer?

It is important to wear a retainer after orthodontic treatment because it helps stabilise the teeth in their new position. If you want your teeth to stay in their ideal position, it is best to wear a retainer as prescribed by your Smilers® practitioner. As such, Smilers® have developed a very thin invisible, painless retainer called Smilers® Fix, which can finalise, at the discretion of your practitioner, your treatment with invisible aligners.

Since my braces were removed, my teeth have moved. Can Smilers® treatment correct this?

Many patients were treated with braces in the past, often during their teens. Smilers® can generally correct the shift that occurs after removal of the braces (called recurrence).

What is the minimum age for starting Smilers® treatment?

With their experience and special training, Smilers® practitioners can use Smilers® invisible dental aligners to straighten teeth in the majority of adults and adolescents. If your child is a teenager, contact your Smilers® practitioner to find out if treatment with invisible aligners is right for him or her.

Are there any dietary restrictions during treatment?

No. Unlike traditional braces and wires, you can eat and drink whatever you want during your treatment because you can remove your dental aligners. For good oral hygiene, they also make it easy to brush and floss your teeth after each meal, before wearing back your aligners.

Can I continue to do sport during treatment?

Yes! Unlike braces, your Smilers® clear aligners allow you to live your passion without having to worry about braces that could cut into your mouth and be painful. If your sport requires mouthguards, simply remove your dental aligners and you’re ready!

What is the best way to clean my aligners?

Aligners are removable, allowing you to continue brushing your teeth as you normally would. To clean your dental aligners, you have two options: our Smilers® kits or simply brushing and rinsing with warm water. That’s it.

How often should I wear my aligners?

You must wear your aligners at all times throughout the treatment, except when eating, and brushing or flossing your teeth. We recommend that you wear them 22 hours a day.

Can I smoke with my aligners?

Smoking with your aligners is not recommended so as not to alter their  transparency and to prevent them from gradually turning yellow. 

Do I have to remove my aligners to drink tea or coffee?

It is not recommended to consume sugary or hot drinks with your aligners as these can slightly deform your dental aligners.

Can I chew gum with my aligners?

Chewing gum is not recommended as it may stick to your aligners. We recommend removing them before each meal or snack.

Will aligners affect my speech?

Most patients do not notice any change in their speech. However, as with all traditional orthodontic appliances, a period of adjustment is necessary.
