Invisalign or ‘invisible braces’ are a widely adored treatment used to more comfortably and discreetly straighten teeth, providing an alternative to traditional metal braces. While Invisalign has been around for some time now, we still find patients asking frequently asked questions about them. 

And as with all new treatments, they are surrounded by various questions about what it is exactly they can and can’t do. We have compiled an Invisalign FAQ to answer just that. 


Invisalign Gaps & Crowding Frequently Asked Questions

Invisalign can be a great way to straighten your teeth without the ordeal of undergoing tightening of wires, elastic bands and the visual change. Offering a more comfortable, subtle alternative to standard braces with a bunch of benefits.

If you’re still debating on whether braces or Invisalign is better, or have already decided on Invisalign we have a wealth of information for you to access.

We have found our patients asking frequently asked questions about gaps and crowding when it comes to Invisalign and how they work in comparison to traditional braces. Our Invisalign FAQ addresses exactly what Invisalign is and isn’t capable of in regards to moving your teeth. 


Can Invisalign Move Or Change Your Jawline?

Yes, Invisalign can move and change your jaw. Depending on the degree in which your jaw needs moving, your dentist may want to move your jaw in position before undergoing any treatment. 

However, attachments and rubber brands can be used alongside your Invisalign to help shift the teeth and jaw into the correct position, to help ensure a healthy bite. 


Can Invisalign Fix Crowding?

Yes, Invisalign can fix crowding of your teeth. Crowded teeth can be caused by numerous factors, the early loss of baby teeth, abnormally shaped teeth, a cleft in the lip or palate. Invisalign can work to amend these issues by applying constant, gentle pressure to help align them properly. 

While severely crowded teeth may require additional treatment, such as removal of any troublesome teeth. Invisalign can work to help align crowded teeth, through moving each tooth up 0.2mm with each new aligner – making for more room in your mouth as your teeth are correctly aligned.


Can Invisalign Fix Gaps?

Yes, Invisalign can fix gaps. Gaps are the name given when there are empty spaces between two or more of your teeth making for gaps between your teeth. This can cause numerous problems such as food getting stuck between your teeth, possibly even contributing to gum disease.

Invisalign is one of the quickest methods to fix gaps in your teeth, but every mouth is different and can differ in length. Invisalign works to move your teeth roughly 0.2mm per new set of aligners. 

It is important that in severe cases aligners are worn for a duration after treatment to ensure gaps don’t reform. 


Can Invisalign Move Molars?

Yes, Invisalign can move molars. Molars are awkward in the sense they’re quite awkward to move or straighten even for traditional braces and can be known to be the cause of a lot of pain. 

Invisalign works to move molars as it would any other teeth, however, depending on the severity of the molars depends on how long it will take to move/straighten. It can sometimes take numerous trays to see any movement to molars.


Can Invisalign Correct Your Bite?

Correcting your bite is a large reason why people invest in braces and Invisalign, as it can cause numerous issues such as damage to your gums and other teeth, alteration in appearance and pain when chewing. 

This being said, Invisalign can correct your bite.


Can Invisalign Braces Fix Overbite?

Yes, Invisalign can fix an overbite. Overbites are one of the most common dental problems that seem to crop up, and Invisalign can definitely fix them. 

There are different means of fixing overbites dependant on your age:

  • Still growing (around the age of 12 years old), with the right type of Invisalign appliance it’s possible to redirect a patient’s tooth growth to influence the position of the jaw and bite. This is through an application called the Invisalign Mandibular Advancement.
  • Adults can no longer make use of the above-mentioned appliance and instead have to rely on other means. Depending on the severity the Invisalign alone may work to fix an overbite, while more severe cases warrant additional means. Elastic bands or a small bar called a motion appliance are used to treat harder cases.

Ultimately the answer is yes, Invisalign can be used to treat overbites.


Can Invisalign Braces Fix Underbite?

Yes, Invisalign can fix an underbite. Underbites can become quite a problem if left untreated as they can contribute to faster tooth decay, poor oral hygiene and more. 

An underbite is when your teeth are incorrectly positioned and your bottom teeth appear in front of your top set of teeth.

Invisalign can be used to fix underbites, however, more severe cases may require additional treatment such as surgery to move your jaw or elastic bands and wires.


Can Invisalign Damage Teeth?

Yes, Invisalign can damage your teeth – however, this is mostly if proper instructions have not been followed regarding your invisible braces. 

Invisalign is not painless, it’s pretty common for your teeth to feel sore and uncomfortable – especially after a new, tightened set. Even so, this shouldn’t cause any damage to your teeth. 

It is possible to cause damage to your teeth through mistreatment of your aligners, such as drinking any fluid that isn’t water. Other liquids such as fizzy drinks and fruit juices can get stuck under your aligner and damage your teeth. 

Invisalign works to cause a cellular response in the roots of the teeth in order for them to move. On very rare occasions this can lead to damaging the ends of your teeth. 


Can Invisalign Bring Teeth Forward?

Yes, Invisalign can be used to bring teeth back and forward. Invisalign can be used to move the lower teeth back so they sit behind your front teeth and vice versa, they can be used to bring your upper teeth forward to sit in front of your bottom teeth.

While some overcrowding, overbite/underbite issues may require additional treatment, such as elastics or the use of other braces – Invisalign can be used to bring teeth forward.


Can Invisalign Fix Very Crooked Teeth?

Yes, Invisalign can be used to fix very crooked teeth. In some cases, another type of braces may be required or additional treatment (but most of the time is due to severe misalignment of the jaw). 

Invisalign can be used to make even the most crooked teeth look perfect, given the right conditions, time and consistency.


Other Invisalign Frequently Asked Questions


Invisalign treatment for the most part is to do with teeth alignment and fixing crowding or gaps in your mouth. But, our patients have also been asking frequently asked questions more about the day-to-day routines of wearing and cleaning your Invisalign

Please see our other Invisalign FAQ answering more generic questions. 


Can Invisalign Only Be Worn At Night?

No, Invisalign can’t just be worn at night. In fact, Invisalign should be worn almost all the time, only being taken out for eating, drinking, brushing and flossing. 

As an advisory target you should be wearing your Invisalign for between 20-22 hours a day, the longer the better. Otherwise, the benefits of wearing them can slowly wear off, and the movements can start to revert. 


Can Invisalign Trays Be Used For Teeth Whitening?

No, it’s heavily advised not to use Invisalign trays for teeth whitening. While this hasn’t been tested, it can lead to poor results or be unsafe. 


Can Invisalign Be Used For A Night Guard?

Yes and no, depending on the severity. 

If you heavily grind your teeth and as a result need a nightguard, you are most likely ineligible for Invisalign treatment. This is because Invisalign relies on you wearing your aligners during your sleep, which if you require a night guard just isn’t possible. 

If you only slightly grind your teeth, it is possible for your Invisalign to act as a buffer between your teeth while grinding. However, grinding and clenching can quickly lead to your Invisalign being worn down, or even worse breaking.

This would have to be discussed on a case-by-case basis by your orthodontist where they look at your situation and requirements and see if you’re eligible. 


Does Invisalign Hurt?

Yes, Invisalign can hurt. For most patients, Invisalign provides a less painful, discreet and more comfortable experience when compared to traditional braces.

But for a portion of patients, Invisalign can be painful especially at the beginning of each new aligner. This pain usually wears off in a few days after your teeth adjust. 


Does Invisalign Affect Speech?

Invisalign shouldn’t affect speech. While causing any changes to your speech is unlikely, it is possible. If so, your tongue should soon get used to the aligner in your mouth and relax.
