Would you like straighter teeth without a noticeable metal brace? With invisible braces in Leiden, you can have your teeth corrected in a discreet manner. Transparent aligners, such as Invisalign and SureSmile, are particularly popular among adults who want to improve their smile without visible brackets or wires.
At We Smile Tandartsen in Leiden, we offer treatments with transparent aligners. In this article, you can read how they work, who they are suitable for, and what you can expect from the treatment.

What is Invisalign and how do invisible braces work?

Invisalign is a brand name for an orthodontic treatment using clear, removable covers that fit over your teeth. These covers are called aligners.
At We Smile Tandartsen, we work with transparent aligners, including SureSmile. The principle is similar: a series of custom-made aligners gradually move your teeth into the desired position.
Invisible braces offer several advantages:

  • Virtually invisible: the transparent covers are hardly noticeable.
  • Removable: you remove them while eating and brushing your teeth.
  • No metal brackets: this means there are fewer protruding parts.
  • Digital planning: the desired tooth movements are planned in advance.

For a good result, it is important that you wear the aligners consistently.

Who are invisible braces suitable for?

More and more adults are choosing treatment with transparent aligners. Not only for aesthetic reasons, but also because better dental alignment can make cleaning the teeth easier.
Aligners can be used for, among other things:

  • Crooked or rotated teeth
  • Gaps between front teeth
  • Mild to moderate crowding
  • Certain bite misalignments
  • Teeth that have shifted again after previous orthodontic treatment


Not every misalignment is suitable for treatment with aligners. For complex dental issues, traditional braces or treatment by an orthodontist may be better.
During an intake, we assess which options are suitable for your teeth.

How does treatment with transparent aligners proceed?

Treatment with invisible braces consists of several steps.

Intake and digital dental scan

During the first appointment, we examine your teeth, molars, and gums. With our digital 3D scanner, we accurately record your dental alignment.
A healthy mouth forms the basis for orthodontic treatment. Any cavities or gum problems must therefore be assessed and, if necessary, treated first.

Personalized treatment plan

Based on the scan, a digital treatment plan is drawn up. This shows you which tooth movements are planned and what result we expect.
We discuss the possibilities, treatment duration, and costs before you decide.

Wearing the aligners

You will receive a series of transparent aligners that you change according to a fixed schedule.
Typically, you wear the aligners for 20 to 22 hours per day. You remove them while eating, drinking beverages other than water, and cleaning your teeth.

Check-ups and maintaining the result

During check-up appointments, we assess whether your teeth are moving according to plan. Sometimes additional aligners are needed to achieve the desired result.
Afterward, you will receive a retainer to prevent your teeth from shifting again.

How long does treatment with Invisalign or SureSmile take?

The treatment duration depends on the position of your teeth and the desired correction.
For minor corrections, treatment may take a few months. More extensive treatments often take 6 to 18 months or longer.
Your own commitment also plays an important role. If you do not wear the aligners sufficiently, the treatment may be delayed.
During the intake, we will provide you with a personal estimate of the treatment duration.

Do invisible braces hurt?

Treatment with transparent aligners is usually well-tolerated.
Especially when you place a new aligner, you may experience some pressure or sensitivity for a few days. This is because the teeth are being moved gradually.
Sometimes the edges of an aligner can cause slight irritation to the tongue or cheek.
Are you experiencing persistent pain or does an aligner not fit properly? Please contact your dentist.

What do invisible braces cost in Leiden?

The costs depend on the number of aligners required, the complexity of the correction, and the duration of the treatment.
At We Smile Tandartsen, the costs for treatment with transparent aligners typically range between €1,250 and €2,600, depending on the treatment plan.
During the intake, you will receive an explanation of the expected costs and the components of the treatment.
Orthodontic treatments for adults are usually not covered by basic insurance. Some supplemental insurance policies offer partial reimbursement.

Why do adults choose transparent aligners?

Many adults want to have their teeth straightened but find traditional braces less appealing.
Transparent aligners offer a discreet alternative that is easy to combine with work and social activities.
Additionally, you can remove the aligners while eating and brush and floss your teeth in the usual way.
However, the treatment requires discipline. For a predictable result, the aligners must be worn almost all day.
