Top Queries About Invisible Aligners Answered

When you are an adult looking for a straightforward way to straighten your teeth in 2022, you may be surprised to learn that you have more options available than ever, and most of them are designed to be as discreet as possible.

This means that when you wear them, nobody will be able to spot them, making them ideal for people who have careers or teach at universities or schools. But for many dental patients looking for an easy way to straighten their teeth, invisible aligners like Invisalign Sydney simply sound too good to be true, and they want to know a bit more about the treatment before approaching their dentists to see whether they are suitable for it.

Luckily, in this article, 5 of the key questions that are searched for regarding invisible aligners are answered, so you can get a better idea of whether or not this treatment will work for you.

How do they work?

Invisible aligners work due to their customised shape and the use of vector points. When you approach your dentist to see whether you are suitable for invisible aligners, they will take an intraoral scan of your mouth. This will then be sent to a dental laboratory, where they will use digital vector points to move your teeth. These vector points will then be designed to fit a 3D sculpture, which will ultimately become your set of aligners. These aligners will then be printed using a 3D printer, and you will need to wear them every day.

How long will it take for them to straighten my teeth?

The length of time it takes for a clear aligner to move your teeth will depend on the severity of the misalignment being corrected and whether or not you adhere to your dental team’s advice about wear.

In most cases, teeth can be straightened using invisible aligners in around 3 to 9 months, but your dentist will be able to provide you with a more accurate timeline for how long your treatment should take.

Can I wear them if I’m having my teeth whitened?

Good question! In most cases of dental whitening, you will need to wear trays to bed, which have the bleaching gel inside them. However, this will cause an obvious issue if you also wear invisible aligners at the same time. Most dentists will advise that you wait for your treatment with invisible aligners to have ended before undertaking dental whitening.

Will they cause a lisp?

Initially, it will take some time for you to get used to wearing an invisible aligner, so you may experience temporary speech impediments such as a lisp. This should gradually reduce when you get used to wearing the aligners.

If you are having long-term issues with your speech, talk to your dentist.

How do I prevent them from rubbing against my inner cheeks?

Aligners are 3D printed, so like many things that are created via this process, they will have sharp edges, which can cause soreness when they rub against the inner cheeks. If you are struggling with this, you should ask your dentist about dental wax, which can soften the edges of the aligner.


Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner.
