How Does Invisalign Work? A Comprehensive Guide

Post by : admin | 25 October 2023

Are you dreaming of a straighter smile but dread the thought of traditional braces? Enter Invisalign, the clear alternative that’s been revolutionising orthodontics. But how does it work? Is it effective? Let’s delve into everything you need to know.

What is Invisalign?

Invisalign is a modern approach to straightening teeth, using a custom-made series of aligners created for you and only you. These aligners are made of smooth, comfortable, and virtually invisible plastic that you wear over your teeth.


This treatment method uses a series of specially crafted aligners that are made of a powerful thermoplastic material. Each aligner straightens your teeth a little more than the last using controlled force. Depending on the type of problem you have, you’ll need to be treated for about three months minimum. The maximum amount of time that treatment takes is about three years.


In general, this treatment method works very well. Whether or not it will work for you depends on a number of factors. Dental issues it can correct include the following:

  • Overbite
  • Underbite
  • Crossbite
  • Gaps in Teeth
  • Misaligned Teeth
  • Other Issues

If you have an underbite or an overbite, then this treatment method will be able to fix these conditions as long as it’s not severe. Severe cases will require a different treatment method. If you have crowded teeth, gaps in your teeth, or if your teeth aren’t lined up properly, then it can help fix these conditions, too. Severe alignment or spacing issues may require traditional braces.

Risks and Precautions

  • Tooth Sensitivity: Some users report mild sensitivity when wearing new aligners.
  • Speech Issues: The aligners may affect your speech initially, causing a minor lisp which usually settles after one week.
  • Oral Hygiene: Since you’ll be wearing the aligners most of the day, maintaining good oral hygiene is crucial.

Maintenance and Aftercare

After completing your Invisalign treatment, you’ll likely need to wear a retainer to prevent your teeth from shifting back to their original positions. Regular dental check-ups are also essential.


Invisalign offers a flexible, nearly invisible solution for straightening teeth. While it has its downsides, like cost and the discipline required, it’s an attractive alternative for many people. Generally, it’s best to see an orthodontist when you are considering this treatment method because they are very skilled in this area of treatment. For best results, find an Invisalign Preferred Provider.
