Underbites can affect your oral health, facial appearance, and overall well-being. While metal braces and surgery were once the go-to solutions, many patients today ask: “Can Invisalign fix underbite?” The answer is yes, in many cases, Invisalign can effectively treat underbites, especially those caused by dental misalignments.
At Palisades Dental Care, our experienced dental professionals offer personalized Invisalign treatment plans to help patients in Dumont, NJ, achieve healthy, aligned smiles.
In this article, we’ll discuss the safety of Invisalign, its benefits, potential risks, and everything you need to know to make an informed decision about whether Invisalign is the right choice for your smile.
What Is an Underbite?
An underbite occurs when the lower front teeth extend beyond the upper front teeth. This condition can be caused by various factors, including genetic jaw development, childhood habits like thumb-sucking, injury or trauma to the jaw, or poor oral habits over time. Underbites can vary in severity, ranging from mild misalignment to more severe skeletal irregularities.
If left untreated, an underbite can lead to several complications. It may cause jaw pain and temporomandibular joint (TMJ) issues, making it difficult to open and close the mouth without discomfort. Additionally, an underbite can affect speech and make chewing challenging. Over time, the misalignment can lead to tooth wear, enamel erosion, and a higher risk of gum disease and cavities. It can also create facial asymmetry, affecting the overall appearance of the face.
Early intervention and diagnosis from a licensed dentist or orthodontist are essential in preventing these complications and improving both function and aesthetics.
Types of Underbites
Underbites can be categorized into two main types:
1. Dental Underbite
A dental underbite occurs when the misalignment happens due to the teeth, rather than the jawbone. This type of underbite is typically caused by:
- Overgrowth of the lower teeth
- Underdevelopment of the upper teeth
Dental underbites are often easier to treat with Invisalign or traditional braces, as they only involve the teeth and not the jaw itself.
2. Skeletal Underbite
A skeletal underbite is a more complex condition caused by the positioning of the jawbones rather than just the teeth. In this case, the lower jaw extends further than the upper jaw, causing the lower teeth to overlap the upper teeth. This type of underbite may require more advanced treatments such as jaw surgery (orthognathic surgery) in addition to Invisalign or braces.
3. Functional Underbite
A functional underbite occurs when the teeth misalign due to habits such as thumb sucking or prolonged pacifier use in childhood. These habits can push the lower teeth forward. This type can often be treated with Invisalign or other orthodontic treatments, depending on the severity.
4. Class III Malocclusion
Class III malocclusion is another term used for a severe underbite, where the lower teeth and jaw significantly protrude forward compared to the upper teeth. This condition often requires a combination of orthodontic treatment and jaw surgery to achieve optimal results.
Can Invisalign Fix Underbite?
Invisalign can successfully correct many underbite cases, particularly mild to moderate underbites caused by dental misalignment (not jawbone structure).
These clear aligners work by gradually moving your teeth into a better position using a series of custom-made, removable trays. Invisalign can also be combined with elastics or attachments for more complex movements.
However, severe skeletal underbites may require:
- Orthognathic (jaw) surgery in combination with Invisalign
- Referral to an orthodontist or oral surgeon
How Invisalign Corrects an Underbite
- Comprehensive Dental Evaluation: Our dentist will evaluate your bite and jaw using digital impressions, photographs, and X-rays. If your underbite is dental in nature, Invisalign can likely be recommended.
- Customized Treatment Plan: Using Invisalign’s proprietary software, we design a step-by-step plan to shift your teeth into proper alignment. You’ll even get a digital preview of your new smile.
- Wearing Your Aligners: Each set of aligners is worn for 1–2 weeks, at least 20–22 hours daily. They are only removed for eating, drinking, brushing, and flossing.
- Regular Monitoring: We schedule periodic check-ups to ensure the treatment is progressing as planned. Adjustments may be made if necessary.
Benefits of Using Invisalign for Underbite Treatment
- Discreet Aesthetics: Invisalign trays are clear, making them ideal for adults and teens who want a subtle treatment.
- Comfortable Fit: The trays are made of BPA-free SmartTrack material, customized to your teeth for optimal comfort and control.
- Removable Design: You can maintain good oral hygiene and eat your favorite foods without restrictions.
- Improved Jaw Function: By correcting your bite, Invisalign can reduce jaw strain and improve overall oral function.
- Fewer Office Visits: With Invisalign, you spend less time at the dentist compared to traditional braces.
Why Fixing an Underbite Is Important?
Correcting an underbite improves more than just your smile. It helps:
- Restore chewing efficiency and prevent digestive issues
- Reduce strain on your jaw muscles and TMJ joints
- Prevent enamel wear and reduce the risk of future tooth damage
- Improve facial symmetry and boost self-confidence
According to the American Association of Orthodontists, misaligned bites are one of the top reasons for orthodontic treatment, not just for cosmetic reasons, but for function and health.
Invisalign vs. Braces: Which Is Better for Underbite?
