What are orthodontic aligners?
Orthodontic aligners, also known as aligners, are transparent, removable trays that gradually move teeth into the desired position. They are made from a flexible, biocompatible material that fits the shape of the teeth perfectly. During treatment, patients receive a set of aligners to replace every 1-2 weeks, allowing the teeth to be repositioned gradually.
When should you consider orthodontic aligners?
Orthodontic aligners are mainly recommended for people with mild or moderate bite issues, such as:
- crooked teeth,
- gaps between teeth,
- underbite, overbite, or crossbite (in some cases).
Thanks to their appearance and comfort, aligners are especially popular with adults and teenagers who value discretion and the option to remove them whenever they want, for example when eating or attending important meetings.
Orthodontic aligners vs. fixed braces – the differences
| Feature | Orthodontic aligners | Fixed braces |
|---|---|---|
| Appearance | Transparent, almost invisible | Metal brackets and wires, less aesthetically pleasing |
| Wearing comfort | Removable, comfortable, and free of sharp components | Fixed; may irritate the gums and the inside of the cheeks |
| Treatment time | Usually shorter for mild bite issues | May be longer for more complex cases |
| Oral hygiene | Easy to keep clean – removable during meals | Requires special care to keep the brackets and spaces between the wires clean |
| Cost | Usually higher than fixed braces | Lower than orthodontic aligners |
Who is a good candidate for aligner treatment, and who should avoid it?
Orthodontic aligners are intended for people who:
- want to avoid visible braces – aligners are almost transparent, making them discreet,
- need minor or moderate bite correction – for more complex bite issues, doctors recommend traditional fixed braces,
- play sports or musical instruments – the lack of metal parts eliminates the risk of oral injuries,
-
are allergic to metals – aligners are made from biocompatible material and contain no metal parts,
- travel frequently or lead an active lifestyle – no risk of a broken wire or unexpected emergency visits.
Orthodontic aligners are not recommended for patients with severe or complex bite problems, or for children under 14 whose teeth are still developing. In these cases, traditional braces may be more effective.

Advantages and disadvantages of orthodontic aligners
Advantages:
- appearance – aligners are transparent, making them almost invisible,
- comfortable to wear – the lack of metal parts makes aligners more comfortable and prevents gum irritation,
- easy to maintain hygiene – aligners can be removed while eating and brushing, making it easier to maintain oral hygiene,
- fewer orthodontist visits – compared with traditional braces, which require frequent checkups and adjustments,
- shorter treatment time – for mild bite problems, treatment with aligners may be shorter than with traditional braces.
Disadvantages:
- higher cost – aligners are usually more expensive than traditional braces,
- require consistency – they must be worn for at least 22 hours a day, which takes commitment and discipline,
- not suitable for all bite problems – aligners are effective mainly for mild and moderate cases,
- must be removed while eating – the aligners must be removed before every meal, which can be inconvenient.

The aligners can be removed while eating and brushing, which makes daily hygiene much easier. To clean them, consider the ZENT® Ultrasonic Cleaner – this technology uses cavitation to effectively remove dirt and bacteria even from the smallest gaps in the aligner, without the risk of scratching the surface.
The cleaning cycle takes just a few minutes: simply place the aligners in the water-filled chamber, optionally add a specialized cleaning solution, and turn on the device. Using this method regularly helps keep your aligners clear throughout treatment.

Orthodontists and dental hygienists also recommend:
- cleaning aligners every time you remove them, especially after meals,
- using an ultrasonic cleaner at least once a day, ideally in the morning and evening,
- avoiding cleaning aligners with toothpaste, which may contain abrasive particles,
- regular checks of the aligners’ condition during orthodontic appointments.
Proper aligner hygiene not only keeps them looking good, but is also an important part of preventing cavities and gum disease during orthodontic treatment. Investing in specialized tools for cleaning aligners directly improves treatment comfort and reduces the risk of dental complications.
Diet during aligner treatment
One of the biggest advantages of orthodontic aligners is that you remove them before eating, so there’s no list of forbidden foods like there is with braces. However, that doesn’t mean your diet is irrelevant during aligner treatment. What and how we eat has a real impact on treatment results and dental health.
Orthodontic aligners are removed before every meal, giving you plenty of freedom when it comes to food. However, residue from foods and drinks that stain, such as coffee, tea, red wine, and fruit juices, can build up on your teeth and discolor your aligners. That’s why it’s worth limiting them. It’s also worth limiting sugary and acidic drinks, which weaken enamel and increase the risk of tooth decay, especially when your aligners are in.
In your daily diet, it’s a good idea to include foods that support healthy teeth and gums, such as:
- dairy products (milk, cheese, yogurt),
- fish rich in omega-3,
- leafy greens and eggs.
Another key habit is to brush your teeth thoroughly after every meal, before putting your aligners back in, so food particles don’t get trapped under them. Drinking plenty of water and rinsing your mouth after meals are simple but effective ways to maintain good hygiene when you don’t have a toothbrush handy.
Costs of orthodontic aligner treatment
The cost of orthodontic aligner treatment depends on the complexity of the issue, the number of aligners, and the location of the clinic. In Poland, the total cost of treatment usually ranges from PLN 8,000 to PLN 20,000. It is worth remembering, however, that many clinics offer installment plans, allowing you to spread the cost over time.
Summary
Orthodontic aligners are an innovative solution for people who want to enjoy straight teeth in a discreet and comfortable way. Thanks to their transparent material, they are almost invisible, and being able to remove them makes it easier to maintain good oral hygiene. However, aligner treatment isn't for everyone - it is most effective for mild and moderate malocclusions.
People with more serious problems may have to choose traditional fixed braces. Aligners are also more expensive than fixed braces and require a high degree of commitment, which is worth considering before making a decision. Treatment costs between PLN 8,000 and 20,000, but for many patients, the benefits of this method, such as appearance and comfort, outweigh its limitations.
FAQ - Frequently Asked Questions About Orthodontic Aligners
Does aligner treatment hurt?
At the start of each treatment stage, when you put in a new aligner, you may feel slight discomfort or pressure - this is a normal sign that your teeth are moving. However, the pain is usually much milder than with fixed braces and goes away after 1-2 days. If the discomfort is severe or lasts longer, consult your orthodontist.
Do I have to wear aligners around the clock?
Aligners should be worn for at least 22 hours a day. Occasional short breaks should not significantly affect treatment, but regularly failing to wear them can prolong treatment or reduce its effectiveness. If this happens, let your orthodontist know so they can assess whether you need to repeat a particular stage.
Are orthodontic aligners covered by the NFZ?
Unfortunately, orthodontic aligner treatment is not covered by the National Health Fund (NFZ). The fund only covers some orthodontic treatment costs for children and young people up to the age of 12, and only with fixed or removable braces. Aligner treatment must be paid for entirely out of pocket.
How long does orthodontic aligner treatment take?
The duration of orthodontic aligner treatment depends primarily on the complexity of the malocclusion. For mild cases, treatment can take as little as 6 to 12 months, while moderate cases can take one to two years. Each aligner in the set is worn for 1-2 weeks, then replaced with the next one. Your orthodontist will determine the total treatment time after a thorough assessment.
How long do you need to wear a retainer after treatment?
After orthodontic aligner treatment, you need to wear a retainer - a special appliance that keeps your teeth in their new position. You usually wear it around the clock for the first few months, then only at night. In many cases, orthodontists recommend wearing a retainer indefinitely, at least a few nights a week, to prevent relapse.
