If your teenager needs their teeth straightened but dreads a mouth full of metal, clear aligners are the modern answer. They are see-through, removable trays that gradually move teeth into place, with no brackets and no wires. For 13 to 18 year olds in particular, Invisalign Teen is purpose-built for a growing mouth and a busy school life. This guide explains how clear aligners work for teens, how they compare to braces, what age suits them, and what treatment costs at Radiant Smiles in Perth.
Key Takeaways
- Clear aligners give teens a discreet, removable option instead of traditional metal braces
- Each aligner is custom-made for your teen’s teeth and gradually shifts them into the right position
- They need to be worn 20–22 hours a day, with a fresh set swapped in every 1–2 weeks
- They work brilliantly for mild to moderate alignment issues, though severe cases might need different treatment
- Regular visits to the orthodontist keep everything on track and catch any issues early
What are Clear Aligners for Teens?
Clear aligners are custom-made trays of clear, medical-grade plastic that fit snugly over your teen’s teeth. Each tray is worn for one to two weeks, then swapped for the next in the series, and each one nudges the teeth a little closer to their final position. They are worn 20 to 22 hours a day and taken out only to eat, drink anything other than water, and brush. Because they are nearly invisible, most people will not notice your teen is wearing them at all. The best known brand, and the one we use for teenagers, is Invisalign Teen.
How Invisalign Teen is built for teenagers
Invisalign Teen is not just the adult product in a smaller size. It has three features made specifically for younger patients and the parents footing the bill:
- Eruption tabs. Teenagers are still growing, and back teeth and canines may not be fully through yet. Invisalign Teen aligners include built-in space that allows these teeth to come through naturally during treatment, so you do not have to wait until every adult tooth has erupted to start.
- Compliance indicators. Each aligner has a small blue dot that slowly fades the more it is worn. It gives both you and the dentist an honest picture of whether your teen is wearing them enough, which takes the guesswork out of those 20 to 22 hours a day.
- Free replacement aligners. Teenagers lose things. Invisalign Teen includes a set of free replacement aligners, so a tray left on a lunch tray does not mean an expensive setback.
What are the Benefits of Clear Aligners for Teens?
Clear aligners offer several benefits over traditional braces, especially for teens:
- Discreet Appearance: Clear aligners are made from clear plastic, making them nearly invisible when worn. This is especially appealing for teens who want to straighten their teeth without the obvious look of metal wires and brackets.
- Comfort: Aligners are smooth and don’t have sharp metal parts, unlike braces, which can cause irritation to the mouth and gums. This makes them a comfortable choice for teens during their treatment.
- Removable: Clear aligners are removable trays, allowing teens to take them out when eating, drinking (except for water), or cleaning their teeth. This gives teens the freedom to enjoy their favourite foods without restriction, which is not possible with traditional metal braces.
- Improved Oral Hygiene: Since aligners are removable, it’s easier to brush and floss compared to braces, reducing the risk of plaque build-up, cavities, and gum disease.
- Fewer Office Visits: With traditional braces, adjustments need to be made regularly. Clear aligners require fewer office visits, typically every 6-8 weeks, which is a time-saver for busy teens.
Clear aligners vs braces for teens
Traditional braces still do an excellent job, especially for complex cases. The table below summarises the key differences for most mild to moderate cases. The trade-off with aligners is discipline — they only work while they are in the mouth. Braces, being fixed, do the work whether your teen remembers or not. We help you weigh this up honestly at the consultation.
| Feature | Clear Aligners | Traditional Braces |
|---|---|---|
| Appearance | Clear plastic, nearly invisible | Metal brackets and wires, highly visible |
| Comfort | Smooth, no irritation | Can cause mouth irritation from brackets and wires |
| Removable | Yes, for eating and cleaning | No, fixed to teeth |
| Food Restrictions | None | Certain foods must be avoided |
| Maintenance | Easy to clean, no brackets or wires | Requires special care around brackets and wires |
| Treatment Duration | Generally faster for mild cases | Can take longer for complex issues |
| Cost | Similar to braces, often higher for Invisalign® | Generally similar or slightly lower than aligners |
What age can a teen start clear aligners?
There is no single magic age. What matters is how far through your child’s adult teeth are, not the number on their birthday. Many 13 and 14 year olds are ready, and the eruption tabs in Invisalign Teen mean treatment can begin while a few back teeth are still coming through. Aligners suit mild to moderate crowding, gaps and many bite problems. For severe cases, we may recommend braces or a combination of treatments. A free consultation and scan is the only reliable way to know if your teen is a good candidate.
How long does treatment take?
It depends on how much movement is needed. Simple cases can be finished in around six months, while more involved cases take up to two years. The typical teenager falls somewhere around 12 to 18 months. Consistent wear is the single biggest factor: a teen who wears their aligners the full 20 to 22 hours a day stays on schedule, while one who leaves them out for hours will stretch the treatment out.
How much do clear aligners for teens cost in Perth?
At Radiant Smiles, clear aligner treatment is covered by our all-inclusive Invisalign plan, which starts from $5,500. The exact cost depends on how complex your teen’s case is and how long treatment runs, which we confirm with a fixed quote at your free consultation. You can see the full breakdown on our Invisalign Perth cost page.
Terms & Conditions: Pricing is indicative only of an average cost. Pricing can vary depending on the medical condition and requirements of the patient as well as the materials used.
To make it manageable, we offer interest-friendly payment plans through Total Lifestyle Credit and other finance options, so the cost can be spread over the course of treatment rather than paid up front. If you have private health insurance with orthodontic extras, you can usually claim a rebate as well.
Helping your teen stay on track
Clear aligners reward consistency, and a little support from home makes all the difference:
- Set a couple of phone reminders so the aligners go back in promptly after meals.
- Use the compliance indicator dots as a simple, no-argument check on wear time.
- Build a habit of storing them in their case, never wrapped in a napkin where they get binned.
- Keep the regular check-ups, where we track progress and catch any slip early.
How do I Care for My Teen’s Clear Aligners?
Proper care is essential for keeping clear aligners in good condition. Here are some tips for maintaining them:
- Clean Regularly: Brush the aligners gently with a toothbrush (without toothpaste) and rinse them with cool water to remove plaque and bacteria.
- Avoid Hot Water: Never clean your teen’s aligners with hot water, as it can cause them to warp and lose their shape.
- Store Properly: When not in use, store the aligners in their case to avoid damage or loss.
- Rinse After Every Meal: After eating or drinking, encourage your teen to rinse their aligners to keep them clean and fresh.

FAQs About Clear Aligners for Teens
Can Invisalign fix TMJ issues in teens?
Sometimes it can help. A misaligned bite is one factor that can contribute to jaw strain, and correcting the alignment may ease it. However, jaw joint (TMJ) problems have several causes and are not always solved by aligners alone. We would assess your teen properly before suggesting Invisalign as part of any plan, rather than promise it as a cure.
Can my teen wear aligners during sport?
For most sports, yes, aligners can stay in. However, for contact sports that require a mouthguard, the aligners should come out and a proper mouthguard worn instead. Aligners are not designed to absorb impact. The removal time counts toward the daily hours out, so it is worth factoring in if your teen trains frequently.
Will aligners affect my teen’s speech?
There may be a short adjustment period of a few days where your teen notices a slight lisp or change in how certain sounds come out. This passes quickly as the mouth adapts to the trays. Most teens find their speech returns to normal within a week, and the aligners are thin enough that the effect is minor.
Does my teen need a retainer after treatment?
Yes. Once the active aligner treatment is complete, a retainer is needed to hold the teeth in their new position. Without it, teeth will gradually shift back over time. We will advise on the right retainer type and how long it needs to be worn, typically full time at first, then nights only long term.
