Clear aligners have revolutionized orthodontic treatment, offering a discreet and convenient alternative to traditional braces. However, one of the most common questions prospective patients ask is: How long do clear aligners take to straighten teeth?
The answer depends on many factors—from the severity of the dental issue to patient compliance and the technology used. In this guide, we’ll break down the average timeline, what affects it, and how at-home systems like Alignero offer faster, doctor-supervised results.
What Are Clear Aligners?
Clear aligners are transparent plastic trays that gradually shift your teeth into proper alignment. Unlike traditional braces, they’re removable, nearly invisible, and typically more comfortable. Each set of aligners is worn for about two weeks, progressively moving teeth until the desired result is achieved.
At-home clear aligner brands like Alignero provide a remote-first model: customers start with an impression kit at home, receive a dentist-approved treatment plan, and complete their entire journey with remote monitoring—saving time and cost.
How Long Do Clear Aligners Take?
Mild Cases
People with slight spacing or crowding can often complete treatment in 4 to 6 months.
Moderate Cases
Cases involving multiple teeth or mild bite adjustments typically take 6 to 12 months.
Severe Cases
Severe misalignments or bite corrections might require 12 to 18 months, often handled better with in-office aligners or braces.
With Alignero, most users complete treatment within 4 to 8 months depending on case complexity and compliance.

Factors That Influence Aligner Treatment Time
1. Complexity of Your Case
If your teeth need major rotation, leveling, or bite correction, your plan will be longer. Mild spacing or crowding moves more quickly.

2. Daily Wear Time
Aligners should be worn 20 to 22 hours a day. Removing them for long periods (even occasionally) can delay treatment.
3. Age
Younger patients may see slightly faster results due to more adaptable bone structures, but adults can also achieve excellent outcomes.
4. Aligner System Used
At-home systems like Alignero focus on mild to moderate cases and are designed to move teeth efficiently. In-office systems like Invisalign may address more complex needs but involve more in-person visits, which can extend timelines.
5. Monitoring & Adjustments
Systems that include regular monitoring (such as Alignero’s remote dental oversight) can make timely adjustments that help avoid delays.

How to Stay on Schedule
To complete treatment on time (or even faster), follow these guidelines:
- Wear your aligners 20–22 hours daily
- Avoid skipping aligner stages
- Clean aligners and brush after meals
- Keep aligners stored safely in their case
- Check in with your provider consistently
Skipping trays, delaying switching schedules, or poor hygiene can prolong treatment and negatively impact results.

What Happens After Treatment?
Once your teeth are aligned, the job isn’t finished. Retainers are essential to maintain your new smile. Without retainers, teeth may shift back to their original position—a process known as relapse.
Alignero includes post-treatment retainers and offers guidance on how long you’ll need to wear them. Typically, retainers are worn full-time for a few weeks, then nightly long-term.
Is Faster Treatment Always Better?
Not necessarily. Moving teeth too quickly can lead to discomfort, instability, or damage to the roots. A well-paced, doctor-supervised plan—like Alignero offers—balances speed and safety.
Fast aligners are only as good as the plan behind them. Beware of providers that promise instant results without proper dental oversight.
Realistic Expectations: What You Should Know
- You’ll likely see small changes in your smile within 4–6 weeks.
- Noticeable progress typically becomes visible by month 2–3.
- Final results depend on sticking to your schedule and instructions.
It’s important to be patient—clear aligners are a gradual process, but the results are permanent with proper follow-up.
Summary: So, How Long Do Clear Aligners Take?
| Case Type | Average Time with Aligners |
| Mild (spacing) | 4–6 months |
| Moderate (crowding) | 6–12 months |
| Severe (bite issues) | 12–18 months (in-office only) |
With Alignero, most users complete treatment in under 8 months, thanks to remote monitoring, efficient case design, and a focus on simplicity.
