Does Invisalign Work?

I can understand why you would be asking this question: Does Invisalign Work? You may have been doing some online research and found some people have had less than pleasant experiences or found it did not work in straightening their teeth.

I have just been back from a major international conference on Invisalign® and have had the chance to exchange ideas with many other top experts in this field. A lot has changed in the features of Invisalign® that now make achieving your smile more predictable and backed up by scientific data. Even the material itself is better than that of Invisalign® of 5 years ago.

For those of you who are new to this, Invisalign® is a series of custom designed and made clear removable aligners that are changed regularly, usually between 7-14 days, each of them moving your teeth closer towards your new smile. An easy way for understand this is to compare Invisalign® to the individual bricks that build a house. It is not the individual bricks itself that lead to a beautiful house, but it is their planned and coordinated delivery of these bricks in stages, that creates the framework for a beautiful house and design.

Us as orthodontists, are specially trained in the movements of teeth, know this and are able to stage the delivery to you of the Invisalign® plates (generally called “aligners”), so the final outcomes are predictable, achievable and effective in doing so.

What is the different between braces and Invisalign?

Compared to braces, there are several advantages. Invisalign is easier to keep clean, and is more comfortable. Loose braces are generally not a concern and if you play a lot of contact sports or wind music instruments ie: trumpet, saxophone, clarinets, flutes, you don’t need to work about braces rubbing against your cheeks or lips.

As with any appliance, when asking Does Invisalign work for me?there are a few things to consider with Invisalign:

  1. There are small tooth coloured “attachments” that are temporarily glued on the outsides of certain teeth, including some front teeth. This is to help move and straighten the teeth. These are generally removed at the end of your treatment.
  2. Yes, coloured lip stick and lip gloss may stick to the aligners, so you may need to sway to a clear one.
  3. There can be a temporay lisp when you first start Invisalign® with certain sounds ie: the “s” ones. Generally, this does improve with time.

What Invisalign will not do:

  • If you are not prepared to wear the Invisalign® for 20-22 hours a day, then it will not move your teeth to plan, and there is a greater chance of the Invisalign not fitting your teeth. A non-fitting Invisalign® can make speaking a bit more awkward and led to some adults reducing their wear in the daytime further.
  • If there are very large spaces that need closing, Invisalign® may not be able to do this entirely in its own and need some help with some braces attached to a few teeth.
  • If you have a very deep bite, Invisalign® may not be able to do this by itself and may need help with some braces too.

In review, Invisalign® can be a great appliance that can suit your needs. To find out more, call our practice on 02-8814 9941 or book a complimentary one-on one orthodontic consultation with our doctor and team at
