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 flexible, biocompatible material that perfectly fits the shape of the teeth. During treatment, the patient receives a set of aligners to change every 1-2 weeks, allowing systematic correction of tooth alignment.

When is it worth choosing orthodontic aligners?

Orthodontic aligners are mainly recommended for people with mild or moderate bite issues, such as:

• crooked teeth,
• gaps between teeth,
• overbite, underbite, or crossbite (in some cases).

Thanks to their aesthetics and comfort, aligners are especially popular among adults and teenagers who value discretion and the ability to remove them at any time, e.g., during meals or important meetings.

Orthodontic aligners vs fixed braces – differences

Who is suitable for treatment with aligners, and who should avoid them?

Orthodontic aligners are designed 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 absence of metal parts eliminates the risk of oral injuries,
• are allergic to metals – trays are made of biocompatible material without any metal parts,
  
• travel a lot or lead an active lifestyle – no risk of broken wires and emergency visits.

Orthodontic trays are not recommended for patients with severe bite defects, complex bite issues, or children under 14 years old whose dental growth process is not complete. In such cases, traditional fixed braces may be more effective.

Advantages and disadvantages of orthodontic trays

Advantages:

• aesthetics – trays are transparent, making them virtually invisible,
• comfort of wearing – the absence of metal parts makes trays more comfortable and prevents gum irritation,
• ease of maintaining hygiene – trays can be removed during eating and brushing, making oral hygiene easier,
• fewer orthodontist visits – compared to fixed braces, where check-ups and adjustments are frequent,
• shorter treatment time – for mild bite defects, treatment with trays can be shorter than with fixed braces.

Disadvantages:

• higher cost – trays are usually more expensive than traditional fixed braces,
• require consistency – they must be worn at least 22 hours a day, which demands commitment and discipline,
• not suitable for all bite defects – trays are mainly effective for mild and moderate defects,
• need to remove during meals – trays must be taken off before each meal, which can be inconvenient.

How to care for the hygiene of orthodontic trays?

Trays can be removed during eating and brushing, which greatly facilitates daily hygiene. For cleaning them, consider the ZENT® Ultrasonic Cleaner – this technology uses cavitation, effectively removing dirt and bacteria even from the smallest aligner gaps without the risk of scratching the surface.

The cleaning cycle lasts only a few minutes: just place the trays in the water chamber, optionally add a specialized cleaning agent, and start the device. Regular use of this method helps maintain the transparency of the trays throughout the treatment period.

Orthodontists and dental hygienists also recommend:

• cleaning aligners after every removal, especially after meals,
  
• using an ultrasonic cleaner at least once a day, ideally morning and evening,
  
• avoiding cleaning aligners with toothpaste, which may contain abrasive particles,
  
• regular checks of the aligners' condition during orthodontic visits.

Proper hygiene of aligners not only ensures an aesthetic appearance but is primarily an important part of preventing cavities and gum disease during orthodontic treatment. Investing in specialized tools for aligner care directly improves therapy comfort and reduces the risk of dental complications.

Diet during aligner treatment

One of the biggest advantages of orthodontic aligners is that they are removed before eating – so there is no list of forbidden foods, unlike with fixed braces. However, this does not mean that diet during aligner treatment is unimportant. What and how we eat has a real impact on the therapy results and dental health.

Orthodontic aligners are removed before every meal, which provides great dietary freedom – however, residues of staining products such as coffee, tea, red wine, or fruit juices can settle on the teeth and cause discoloration of the aligners. That is why it is worth limiting them. It is also advisable to limit sweet and acidic drinks that weaken enamel and increase the risk of cavities, especially when the aligners are worn.

In the daily diet, it is good to focus on products that support the health of teeth and gums, including:

• dairy (milk, cheese, yogurt),
• fish rich in omega-3,
• leafy vegetables and eggs.

A key habit is also thorough tooth brushing after every meal – before putting the aligners back on, to avoid trapping food residues under the aligner. Drinking plenty of water and rinsing the mouth after meals is a simple but effective way to maintain hygiene when a toothbrush is not immediately available.

Costs of orthodontic aligner treatment

The cost of orthodontic aligner treatment depends on the complexity of the condition, the number of aligners, and the location of the clinic. In Poland, these costs usually range between 8,000 and 20,000 PLN for the entire treatment process. However, it is worth remembering that many clinics offer installment payment options, allowing the costs to be spread over time.
