# How long do invisible aligners take?

One of the first questions when you consider **invisible aligners** is how long it will take to have your smile ready. The honest answer: it depends on your case, but here are real ranges and what you can do not to prolong it.

## Typical duration

Most aligner cases resolve in **4 to 12 months**. Simple cases (mild crowding or small gaps) can be ready in a few months; more complex cases take longer. Each aligner set is usually worn for **1 to 2 weeks** before moving to the next.

## What does the time depend on?

- **The complexity** of the tooth movement you need.
- **Your discipline**: wearing them the indicated hours matters most.
- **Your biology**: everyone responds at a different pace.
- **Follow-up** from the orthodontist to adjust the plan if needed.

## The biggest factor: wearing them 22 hours a day

Aligners only work when you're wearing them. The ideal is **22 hours a day**, taking them out only to eat and brush your teeth. Every hour you leave them out delays the plan. It's the variable you control most.

> Your consistency is half the treatment: aligners don't work in the case.

## Can it be sped up?

The most effective thing is to meet the daily wear, attend your check-ups and follow instructions. There are complementary techniques your orthodontist can assess, but none replaces consistency. At the end, you'll wear **retainers** so your teeth don't drift back.

## Frequently asked questions

### How often are aligners changed?

Usually every 1 to 2 weeks, as your digital plan and orthodontist's review indicate.

### What if I don't wear them the indicated hours?

Treatment lengthens and teeth may not reach the planned position on time, which can require extra aligners.

### How long will I wear retainers?

Retainers are worn after treatment to keep the result; your orthodontist will indicate the schedule.

### How long would your case take?

With a 3D scan we can estimate your treatment time. Book your assessment.
