Clear Aligners for Children
Clear aligner treatment is an orthodontic method aimed at aligning teeth to their ideal positions and correcting dental misalignments. Compared to traditional braces, clear aligners stand out for their ease of use and aesthetic benefits. Additionally, the shorter treatment duration and the ability to remove the aligners during the day make this option particularly appealing for our younger patients in terms of comfort.
Let's explore why you should consider clear aligners for your child's orthodontic treatment and address some frequently asked questions about this treatment method.

Frequently Asked Questions About Clear Aligners
What Are Clear Aligners?
Clear aligner treatment involves the use of removable aligners that gradually move teeth into their desired positions, correcting misalignments. Each aligner is custom-made and worn for a set period determined by the dentist before moving on to the next one.
At What Age Can Children Start Clear Aligner Treatment?
Children usually start clear aligner treatment around age 7. The deciding factor is not calendar age but dental development: the first permanent molars and at least two front incisors must have erupted in the jaw being treated.
-
Two children of the same age can differ — one may be ready while the other needs to wait for further eruption.
-
The 7-10 age window is when jaw narrowness, crossbite, thumb sucking and tongue thrust problems can be intercepted before they progress.
-
Suitability is decided by clinical examination and intraoral digital scanning. Children who are not yet ready are placed on a six-month review schedule.
Can Children Wear Clear Aligners While They Still Have Baby Teeth?
Yes. Clear aligners can be used during the mixed dentition phase, when baby teeth are still present. The limiting factor is not the presence of baby teeth but whether the required permanent teeth have erupted.
-
During mixed dentition the aligner series is planned around the space baby teeth will leave behind and the permanent teeth still erupting.
-
If a baby tooth was lost early, a space maintainer is assessed before aligner treatment begins.
-
Teeth move faster at this age than in adults, so aligners are changed more frequently.
How Is Clear Aligner Treatment Applied?
Clear aligner treatment is applied in six stages. The full sequence of tooth movements is planned digitally before the first aligner is fitted, so the number of aligners and the expected result are known from the start.
-
Initial Examination: During the initial dental examination, the patient's teeth are thoroughly inspected.
-
Digital Scanning: Using state-of-the-art intraoral scanning devices, the patient's mouth and dental structure are analyzed. In some cases, traditional impression trays may be used to take molds.
-
Treatment Simulation: A computer-generated simulation is created to show the patient how their teeth will change throughout the treatment. This allows the patient to visualize the expected results before starting.
-
Aligner Fabrication: Once the treatment plan is agreed upon, custom clear aligners are created using 3D printing technology. These aligners are designed to correct the specific misalignments of the patient's teeth.
-
Aligner Use: The patient wears each clear aligner for a set period determined by the dentist before switching to the next one in the series.
-
Regular Check-ups: Periodic check-ups are scheduled to monitor progress and make any necessary adjustments to the treatment plan.
Advantages of Clear Aligners
-
Invisibility: Clear aligners are nearly invisible, allowing patients to smile confidently throughout the treatment.
-
Removability: Aligners can be removed for eating, brushing, and flossing, making daily oral hygiene easier.
-
Fewer Adjustments: Unlike traditional braces, clear aligners require fewer adjustments and check-ups.
-
Motivation Through Visualization: Seeing the projected outcome of the treatment beforehand can provide additional motivation, enhancing the success of the treatment.
Clear aligners offer a modern, convenient, and aesthetically pleasing option for orthodontic treatment, especially for younger patients. Discover why this method might be the right choice for your child's orthodontic needs.
How Many Hours a Day Should Clear Aligners Be Worn?
The key to success in clear aligner treatment is wearing the aligners for at least 20 hours a day. To ensure our patients wear their aligners for the required duration, we recommend using apps like TrayMinder.
How Often Are Clear Aligners Changed?
In children, each aligner is replaced every 5-7 days on average. In adults the interval is 10-14 days, so children change aligners roughly twice as often.
-
Total treatment length follows from the number of aligners: a 12-aligner plan changed weekly runs about 12 weeks.
-
The interval is set by the dentist and can shorten or lengthen depending on crowding severity and how fast the teeth move.
-
If an aligner breaks or is lost, do not move to the next one. Contact the clinic — the previous aligner is usually worn longer while a replacement is arranged.
Do Clear Aligners Correct Teeth?
Yes. Clear aligners can successfully correct crowded, spaced and misaligned teeth. Studies indicate a success rate of 80% to 90% for clear aligner treatment.
How Long Are Clear Aligners Worn? What Is the Duration of Clear Aligner Treatment?
The duration of clear aligner treatment varies based on how consistently patients wear their aligners and their level of adherence to the treatment plan. Additionally, the treatment period depends on the patient's dental and jaw structure and the desired outcome.
Clear aligner treatment in children is usually completed in 6 to 18 months. Simple spacing or mild crowding can finish in 6-9 months, and around 12 months is typical. Duration depends on the degree of crowding and how consistently the child wears the aligners.
What Happens When Clear Aligner Treatment Ends?
Once treatment is complete, a retainer is used for a set period to hold the teeth in their new positions and prevent relapse.
-
Retention is part of the treatment, not an optional extra.
-
The dentist decides how long the retainer is worn and how often it is reviewed.
Are Clear Aligners the Same Thing as Dental Plaque?
No. A clear aligner is a custom-made removable orthodontic appliance that moves teeth. Dental plaque is the bacterial film that builds up on tooth surfaces.
-
Aligners are produced individually from a digital scan and move teeth gradually. In Turkish they are called "şeffaf plak", which is why the two terms are often confused.
-
Plaque needs no orthodontic treatment; it is removed by brushing, flossing and regular dental visits.
-
Plaque control matters more during aligner treatment. Inserting aligners over unbrushed teeth traps the bacterial film against the enamel.
Can You Eat While Wearing Clear Aligners?
No. Aligners must be removed before eating and stored in their case. Eating with aligners in place damages them and traps food against the teeth.
-
While eating: with the aligners out, your child can eat anything they like.
-
Hot drinks: tea, coffee and other hot drinks can distort the aligner material and should not be consumed with aligners in.
-
Cold drinks: water and unsweetened cold drinks are safe with aligners in place.
-
Hygiene: brush the teeth and rinse the aligners before putting them back in. This is what keeps the aligners clear rather than cloudy.
Do Clear Aligners Hurt?
No, clear aligner treatment does not cause pain. Each time a new aligner is fitted there may be a mild pressure sensation for 1-2 days, which usually eases from the second day onward.
-
The pressure means the teeth are moving, and it recurs at each aligner change.
-
Unlike brackets and wires, aligners have no sharp edges and do not cause ulcers on the cheeks or lips.
-
Changing aligners at bedtime means most of the pressure sensation passes during sleep.
-
Soft foods and rinsing with cold water help during the first days.
How Much Does Clear Aligner Treatment Cost?
The cost of clear aligner treatment varies for each case. Several factors influence the treatment cost, including the desired outcome, the number of aligners needed, and other associated expenses. A precise estimate of the treatment duration and cost can only be provided after an examination and analysis of the patient's dental structure.
