How Extreme Can Invisalign Fix?

Invisalign can fix a wide range of dental issues, but for extreme cases, maintaining the clarity and hygiene of your aligners is crucial. Using a purple persulfate-free retainer cleaner helps keep your aligners clean and clear, contributing to more effective treatment results.

Understanding Invisalign

Invisalign uses a series of custom-made, clear aligners that gradually shift teeth into their desired positions. The treatment process begins with a consultation where a digital scan or mold of the patient's teeth is taken. This data is used to create a personalized treatment plan, mapping out the movement of each tooth. Patients typically receive a new set of aligners every one to two weeks, wearing them for 20-22 hours per day.

Common Issues Treated by Invisalign

Mild to Moderate Crowding

Crowded teeth are a common problem where teeth overlap due to insufficient space in the mouth. Invisalign effectively treats mild to moderate crowding by gradually moving the teeth into proper alignment.

Spacing Issues

Gaps between teeth can occur due to missing teeth, abnormal growth of the jawbone, or other factors. Invisalign can close these gaps by applying consistent pressure to the teeth, moving them closer together over time.


An overbite, where the upper front teeth overlap the lower front teeth, can be addressed with Invisalign. By shifting the upper teeth back and the lower teeth forward, Invisalign can help achieve a more balanced bite.


In cases of an underbite, where the lower front teeth overlap the upper front teeth, Invisalign can also be effective. Aligners can move the lower teeth back and the upper teeth forward to improve bite alignment.


A crossbite occurs when some of the upper teeth sit inside the lower teeth rather than outside. Invisalign can correct this issue by moving the affected teeth into their proper positions.

Complex Cases and Invisalign

While Invisalign is effective for many orthodontic issues, its ability to treat more complex cases depends on several factors.

Severe Crowding or Spacing

In cases of severe crowding or significant gaps, additional dental procedures such as tooth extractions or interproximal reduction (slenderizing the teeth) might be necessary before starting Invisalign treatment. These procedures create the space needed for the teeth to move effectively.

Severe Bite Issues

Extensive overbites, underbites, and crossbites might require a combination of Invisalign and other orthodontic treatments. In some cases, patients may need to wear rubber bands or other appliances in conjunction with their aligners to achieve the desired results.

Tooth Rotation and Vertical Movement

Invisalign can handle mild to moderate tooth rotations and vertical movements. However, if a tooth needs to be rotated significantly or moved substantially up or down, traditional braces might be more effective.

Jaw Alignment Issues

Problems related to the alignment of the jawbones, such as skeletal discrepancies, often require surgical intervention. Invisalign alone cannot correct these issues, but it can be part of a comprehensive treatment plan that includes orthognathic surgery.

Technological Advancements in Invisalign

Invisalign technology has advanced significantly since its introduction. Innovations such as SmartTrack material, SmartForce attachments, and the use of digital imaging have expanded the range of cases Invisalign can treat. SmartTrack material, for example, allows for more precise and controlled tooth movements, while SmartForce attachments provide additional pressure to specific teeth, making it possible to address more complex movements.

The Importance of a Skilled Provider

The success of Invisalign treatment, especially for more severe cases, largely depends on the expertise of the orthodontist or dentist. A skilled provider can accurately diagnose the issue, create a comprehensive treatment plan, and make necessary adjustments throughout the process to ensure optimal results.


Invisalign is a versatile orthodontic treatment capable of addressing a wide range of dental issues, from mild to moderate crowding and spacing to certain bite problems. While there are limitations to what Invisalign can achieve on its own, advancements in technology and combined treatment approaches have expanded its effectiveness. Patients with more severe orthodontic issues should consult with an experienced provider to determine if Invisalign is a suitable option and to explore other potential treatments that might be necessary for achieving their desired results.

By understanding the capabilities and limitations of Invisalign, patients can make informed decisions about their orthodontic care and achieve the best possible outcomes for their smiles.
