Can Invisalign Fix Jaw Alignment?: A Comprehensive Review in 2026

As a type of orthodontic treatment that uses clear aligners to gradually move teeth into their proper positions, Invisalign is often used to correct common dental issues such as crooked teeth, overcrowding and bite problems.

By moving the position of teeth, this treatment can also influence the vertical height¹ and hence jaw's position. This method has gained popularity in Singapore as a modern alternative to traditional braces for straightening teeth. But can Invisalign fix jaw alignment? Let's find that out here!

What are the common types of dental malocclusions?

1. Crossbite refers to when the top and bottom jaws do not meet up properly due to a lateral misalignment of the upper and lower arches. It is characterised by some of the top teeth sitting inside the lower teeth.
2. Open bite refers to when your upper teeth do not touch the lower teeth when your mouth is closed. As the name suggests, "open bite" makes the mouth look slightly open.
3. Overbite occurs when the upper front teeth extend beyond your lower front teeth. However, about 1-3mm of dental overbite is considered normal.
4. Underbite is the opposite of overbite and it refers to when your lower front teeth are protruding in front of and extending beyond your upper front teeth.

Can Invisalign move my teeth?

Yes, this treatment can move teeth! The treatment comprises a series of upper and lower sets of clear plastic aligners which is worn for no less than 22 hours a day. They are usually only removed by the patient during meals and brushing.

The aligners work by applying gentle pressure to teeth, hence gradually shifting them into their desired position. Every one to two weeks, you switch to a new set of aligners which continue to move your teeth little by little. By doing so, the aligners provide the ability to treat a series of dental issues such as crowding, rotation, closure of gaps and intrusion of teeth.

Can Invisalign fix jaw alignment?

The short answer is yes! In certain situations, as the aligners progressively shift the teeth, bite interferences that were initially preventing the jaws from aligning properly may be eliminated. Consequently, this will allow the jaws to adjust or move into a more favorable position. The aligners themselves, however, do not affect the jaws directly. 

For more complicated jaw misalignment cases, a combination of this treatment option and surgical intervention may be required. In these scenarios, this treatment may be employed before jaw surgery to place the teeth in the proper position and prepare the bite for surgical correction. This combined approach can therefore lead to optimal results regarding both function and aesthetics.

How Invisalign Works to Correct Bite and Jaw Issues?

Invisalign does a lot more than just straighten your smile. It can also help your teeth and jaw fit together better. The process starts with a 3D scan of your teeth as well as digital x-rays. These data lets your orthodontist make a custom treatment plan that's just for you and your teeth.

Invisalign does not use brackets and wires like other teeth straightening methods such as dental braces. Instead it uses aligners that you can take out for daily activities such as eating and cleaning. You wear each set of aligners for one to two weeks. Then you move on to the next set. This helps your teeth get into a position over time.

Your Invisalign dentist may want to add adjunct features to help your bite and jaw. They can put attachments on some of your teeth to help the aligners work better. They may also use bands to help your jaw stay in the right position.

What are the benefits of Invisalign for jaw alignment and bite issues?

The benefits of Invisalign for managing bite and jaw misalignment issues are:

Comfortable Experience: With no brackets or wires, there are no sharp edges that can hurt the cheeks and gums. The aligners are smooth and fit your teeth evenly.

Convenient and Removable: Invisalign aligners can be taken out when you want to eat your meals. It is also convenient to brush and floss your teeth, which helps you keep your mouth clean during the treatment.

Discreet Appearance: The Invisalign aligners are clear so you can barely see them. This is why a lot of teenagers and adults prefer to use Invisalign to straighten teeth, because it is not as noticeable as orthodontic braces.

Preview Your Results: Before starting treatment, you can see what your teeth and bite may look like after the process. This is made possible through Invisalign’s ClinCheck software, which creates a digital simulation of your treatment plan. 

Can Invisalign Fix Jaw Alignment? Frequently Asked Questions

1. Can Invisalign clear aligners fix an underbite?

Invisalign can help correct underbites by using a combination of custom aligners, strategically placed attachments, and sometimes elastics to guide the teeth and jaw into proper alignment. Your orthodontist or Invisalign dentist will evaluate your specific case to determine if Invisalign is the right approach for your underbite.

2. Can Invisalign address severe jaw issues?

Invisalign can help with jaw concerns, particularly in growing children and teens, where the jaw is still growing, and treatment can guide jaw development.

For adults with severe skeletal jaw issues, Invisalign alone is typically not sufficient and may be combined with other approaches such as orthognathic surgery.

3. Does Invisalign correct jaw misalignment in adults?

For adults with mild to moderate jaw misalignment related to tooth positioning, Invisalign can be effective along with its adjunct features, like attachments and rubber bands.

Meanwhile, for more severe cases where the jawbone itself is misaligned, Invisalign alone is usually not enough and may be combined with other approaches such as jaw surgery.

4. Can Invisalign fix jaw alignment without surgery?

Invisalign is effective in fixing the way your jaw is aligned without having to go through surgery. This is the case when the problem is with the position of your teeth, not the jawbone. The aligners have attachments and rubber bands that help guide your teeth and influence the way your jaw is positioned.

For adults who have challenges with the way their jawbone is shaped, surgery is usually the only way to completely manage the issue.

5. How Invisalign differs from braces in jaw and face changes?

Invisalign uses clear, removable aligners that are less noticeable and often more comfortable than traditional braces. Orthodontic braces use metal or ceramic brackets and wires that stay fixed to the teeth, which can offer greater control for complex tooth movements.

How long will the treatment take?

The length of treatment depends on the complexity of your case but for minor cases of dental issues, treatments may be completed in 6 months. Most patients also start seeing results in a matter of weeks!

However, the treatment duration will indeed be longer for more complex cases, especially if a surgical intervention is indicated. For complex cases without surgery whereby the bite and jaw position is planned to change, treatment time may be about 2 years. It is always recommended to consult with your dentist first for a treatment plan that suits your needs.
