There are often a variety of questions that people ask about Invisalign, can it fix an overbite, crowding, crooked teeth and indeed, what can Invisalign NOT fix.

This article is dedicated to answering this great array of questions including, can Invisalign fix protruding front teeth?

What is Invisalign?

Invisalign versus conventional braces
Can you spot which one of these patients is wearing braces?

Invisalign is an orthodontic system which utilises modern computer assisted technology to create clear aligners. These clear aligners sit over your teeth and put a small amount of pressure in the design direction in order to move them.

At the beginning of your treatment planning the software will calculate how many aligners you need and how often you will need to change them, typically this is every 2 weeks.

How long does it typically take for Invisalign to align teeth?

At the beginning of your treatment planning stage you will have your teeth scanned into a computer, your teeth can then be moved on the computer to the ideal location and the computer then calculates how long it will take for this movement to occur to close the gaps and straighten your crooked teeth.

Some treatments can be completed in one year however that average is usually 2 years. It all depends on how much tooth movement is required.

Can Invisalign fix overbite

An overbite is when the top teeth stick out, often when the mouth is closed. Strictly speaking this is actually called an overjet however many people refer to it as an overbite. Often called buck teeth or protruding front teeth. An overbite may have either dental or skeletal causes.

  • Dental causes. This is where the teeth only are in the wrong position.
  • Skeletal causes. this is where either the lower jaw is underdeveloped or the upper jaw is overdeveloped.

Typically Invisalign is able to fix dentally caused overbite much better than skeletal caused overbite. The good news is that most overbites are caused simply by teeth being in the wrong position, severe buck teeth overbites may require orthognathic surgery in conjunction with an orthodontic treatments such as Invisalign.

Can Invisalign fix crowding

In many instances teeth are crowded because of an underdevelopment of the jaw, this leaves not enough room for the teeth to sit in their natural alignment. For this reason, in order to fix crowding there may sometimes be a requirement to remove a tooth to create enough space. Very often the tooth that is removed if the 1st premolar. This then gives enough space to move all of the teeth and straighten them to fix crowding.

In this regard, yes Invisalign can fix crowding.

Can Invisalign push front teeth back

Invisalign can indeed push front teeth back so long as there is enough space for these teeth to move into. If there are gaps behind the protruding front teeth then these gaps will be taken up as the front teeth push back. If there are no gaps and not enough room to push the front teeth back then extraction of a premolar tooth may be required.

Can Invisalign fix protruding upper front teeth

And so on to the main question about whether Invisalign is able to fix protruding front teeth. The answer is definitely yes, although there needs to be room for these front teeth to be moved back into.

If you only have a couple of protruding front teeth, for example 2 front teeth then you may also like to consider dental bonding or other treatments.

The 2 front teeth may look as though they stick out however it may be because the lateral teeth either side of them are actually retruded and not far forwards enough. if this is the case then the teeth either side of the 2 front teeth can be built forwards using dental bonding, this can stop the 2 front teeth from looking as though they stick out.

This can often be a cheaper and quicker option than orthodontics, please speak to your dentist about whether this could be one of your treatment options.

Can you get Invisalign for only the bottom teeth?

Invisalign is suitable for orthodontic treatment on the upper and lower teeth at the same time, just the others or just below is. However most commonly Invisalign is used for the other teeth because it is these which are more visible, however if you are just concerned about straightening lower teeth then Invisalign can also work well to give a straighter smile.

What can Invisalign not fix?

Invisalign is great to fix cosmetic orthodontic issues, straightening, rotating and moving the front teeth is what it is ideally suited for.

More complex orthodontic procedures such as widening your jaw, moving back teeth and correcting extreme malocclusion may be more suitable for specialist orthodontic procedures or other types of orthodontic brace.
