Aligners

# Am I a candidate for invisible aligners?

**Invisible aligners** now solve many more cases than a few years ago, but not all. Here's when they're an excellent option and when it's worth assessing another alternative.

## Cases that usually work very well

- **Crowding** mild to moderate (overlapping teeth).
- **Gaps or diastemas** between teeth.
- **Relapse** from previous orthodontics (teeth that moved again).
- **Bites** mild to moderate that need adjustments.

## Cases that require careful assessment

Some complex malocclusions, large tooth movements or skeletal issues may need braces, special attachments or combined treatments. It doesn't mean aligners are ruled out: it means the orthodontist must plan your case in detail.

## Requirements for a good result

- **Oral health**: no active cavities or gum disease before starting.
- **Commitment**: wearing them 22 hours a day.
- **Follow-up**: attending your in-person check-ups.

> The only way to know your case, timeline and exact price is an assessment with a specialist.

## How do I know if I'm a candidate?

With an assessment and a **3D scan**. From your images, the orthodontist simulates your teeth's movement and defines whether aligners are the best route for you, how many stages you'd need and how long it would take. That way you decide with information, not guesses.

## Frequently asked questions

### Is there a minimum or maximum age?

Aligners work in teens with the right dentition and in adults of any age, as long as oral health is good.

### I had braces before and my teeth moved, do they work?

Yes. Orthodontic relapse is one of the cases that best resolves with aligners.

### What if I have cavities or gum problems?

Oral health is treated first. Once stable, orthodontics can begin safely.

### Find out if you're a candidate

Book your assessment with a 3D scan and check, with no obligation, whether aligners are for you.
