How does Invisalign work?


What is Invisalign?

Invisalign is a type of orthodontic treatment that involves the use of clear aligners made of a thermoplastic material. A series of aligners are custom-made and worn in sequence to gradually move and straighten the teeth. Invisalign treatment has become an increasingly popular means of teeth straightening, as it is virtually invisible, unlike the metal brackets and wires traditionally used to move teeth.

How does Invisalign work?

Once your dentist has determined a treatment course for you, you will be provided with a series of clear aligners. These aligners exert constant, gentle forces on the teeth to bring about changes in position. Each aligner allows for certain teeth to move, mapped out to fulfil your unique treatment plan.

What is involved in the treatment process?

You will first be assessed by your dentist as to whether you are suitable for Invisalign treatment. From there, your dentist will be able to determine how long the course of treatment will be. Once you receive your aligners, you will need to wear them for 22 to 23+ hours per day for the best results. They should only be taken out for eating and cleaning your teeth. In some cases, “attachments” may be placed on your teeth at different stages throughout your Invisalign treatment. These attachments are made of a tooth-coloured composite that bonds to the teeth and helps them grip the aligner, further aiding tooth movement.

What are the benefits of teeth straightening with Invisalign?

The main benefit is aesthetic. They are not only practically invisible but also removable, which means you can take them out to eat and drink, as well as to brush and floss your teeth. The technology we use in the preparatory stages for Invisalign allows you to visualise what the end product will look like. You will be able to see how beautiful your teeth will look once the treatment is complete!
