Introduction to Invisalign clear aligners
Invisalign is a modern, almost invisible orthodontic system that straightens teeth without any metal components. Because the aligners are removable, you can simply take them out while eating or brushing, and wear them for the rest of the day. The result is straight teeth and a beautiful smile without the feeling that braces are holding you back in everyday life. For an overview of orthodontic treatment and braces, see the NHS guide to orthodontics.
For anyone who wants an aesthetic and comfortable way to align their teeth, Invisalign is an excellent alternative to conventional fixed braces. You can learn more about the procedure and how Invisalign aligners are fitted to your teeth at a consultation at the OrthoDental dental centre.
- Most Invisalign treatments take about 6 to 18 months; simple corrections can be as short as around 4 months and complex cases up to 24 months.
- Aligners are worn about 22 hours a day and changed every 7 to 14 days.
- Virtual Care means fewer in-person check-ups while you stay under expert supervision throughout.
- At OrthoDental the standard package is €5,000 and the Invisalign Small package is €2,500 (13 aligners); both cover both dental arches.

How do Invisalign clear aligners work?
Invisalign treatment is based on a series of individually made clear aligners. Each aligner fits your teeth precisely and gradually moves them into the correct position. The aligners are usually changed every 7 to 14 days, with each new set slightly shifting the position of the teeth for a gradual alignment. Invisalign aligners should be worn about 22 hours a day and only removed for eating and cleaning your teeth. Thanks to the smooth material, the aligners are comfortable and do not irritate the soft tissues, which is common with conventional braces.
Invisalign is almost invisible, so most people do not even notice it. This has made it a popular choice among adults who want to correct their bite or want their tooth alignment to be discreet and effective.
Modern 3D planning technology makes treatment fully predictable. Before we begin, we prepare a treatment plan with a simulation that shows how your smile will look at the end of therapy, so most patients look forward to the final result throughout.
The Invisalign treatment process
Treatment with Invisalign is carried out under the expert supervision of an orthodontist or an experienced dentist. At OrthoDental, the process always begins with a detailed examination and analysis of the teeth and bite. This is followed by 3D scanning with an iTero intraoral scanner, which produces an extremely accurate image of your teeth without uncomfortable impressions.
Based on the scans, a digital plan of tooth movements is prepared, which we gradually achieve with the Invisalign aligners, so that even before treatment begins you can see how your smile will look at the end. Once the treatment plan is confirmed, your individual Invisalign aligners are made, which you then change step by step.
For optimal results, it is recommended to wear the Invisalign aligners about 22 hours a day.
How long treatment takes depends on its complexity – on the initial state of the teeth and the plan prepared by the orthodontist. Most cases take between 6 and 18 months, though more complex irregularities can take longer. In any case, because you can change the aligners yourself, fewer visits to the orthodontist are needed.

Virtual Care and how often you need to see the orthodontist
One of the advantages of treatment at OrthoDental is the option of Invisalign Virtual Care. This is a modern digital solution that lets you stay in touch with your orthodontist throughout your Invisalign treatment without frequent visits to the clinic. Through the My Invisalign app and a special camera for photographing your teeth, you can send photos of your progress directly to your orthodontist. They regularly monitor your progress and, if needed, send tailored instructions or invite you in for a check-up if they notice any irregularity, for example if an aligner does not fit perfectly.
How can Invisalign Virtual Care improve your experience?
- Better control over the course of treatment: the orthodontist has a precise insight into progress and can act quickly on any deviations.
- Fewer clinic visits: significantly fewer check-ups are required.
- Ongoing monitoring of results: allows accurate tracking of how well the Invisalign aligners are working and prevents problems from building up.
- Easy photo sharing: the My Invisalign app with video instructions makes documenting your progress easy.
- Fast response from the orthodontist: after sending photos you receive timely feedback and recommendations.
- Direct communication: you can easily report any issues or discomfort through the app.
This way you save the time needed for orthodontic treatment, as in-person visits are only needed at key stages of treatment. Even though fewer visits are required, you are under expert supervision the whole time, which ensures precise and safe tooth movement.
Types of Invisalign packages at OrthoDental
At OrthoDental we offer several types of Invisalign packages tailored to different needs and treatment complexity.
