An underbite happens when the lower teeth extend beyond the upper teeth, leading to an imbalance in the bite. 

This can cause discomfort, affect speech, and even result in jaw pain. One popular treatment for misalignments, including underbites, is Invisalign. 

In this guide, we’ll explore how Invisalign works for underbite correction, its benefits, and any limitations to consider.

Can Invisalign fix an underbite?

Yes, Invisalign can fix an underbite by gradually shifting your teeth into the correct position. Your dentist will customize your treatment plan for the best results.

Key Takeaways

• Invisalign can be an effective treatment for mild to moderate underbites.
  
• The treatment involves using clear aligners to gradually shift the teeth into proper alignment.

What is an Underbite?

An underbite is a type of malocclusion, or misalignment of the teeth, where the lower jaw protrudes further than the upper jaw. 

This results in the lower teeth overlapping the upper teeth, causing an uneven bite. 

Underbite is caused by genetics, thumb-sucking during childhood, or other factors such as jaw growth problems.

Symptoms of an Underbite

People with an underbite may experience a range of symptoms, including:

Difficulty chewing or biting food properly. Speech difficulties, such as lisping. Jaw pain or discomfort, particularly while eating or speaking.

Tooth wear and tear due to misalignment. Treating an underbite is essential not only for cosmetic reasons but also for improving overall dental health and function.

How Invisalign Works for Underbite Correction

Invisalign is a clear aligner system that uses a series of custom-made aligners to gradually move your teeth into better alignment. 

The aligners are made of smooth, comfortable plastic and are virtually invisible when worn. But how exactly does Invisalign work to correct an underbite?

Custom Treatment Plan

The first step in Invisalign treatment is a comprehensive consultation with an orthodontist or dentist. 

During this appointment, your provider will assess the severity of your underbite and determine if Invisalign is suitable for your case. 

Using advanced 3D imaging technology, your provider will create a custom treatment plan tailored to your specific needs. 

The aligners will be designed to shift your teeth into a more natural position, gradually correcting the underbite.

Gradual Shifting of Teeth

Invisalign clear aligners work by exerting gentle pressure on your teeth, gradually moving them into the desired position. 

Over time, you’ll switch to a new set of aligners every few weeks, and with each new aligner, your teeth will continue to shift. 

For an underbite, the aligners will specifically focus on moving the lower front teeth into a more balanced position with the upper teeth, improving the bite.

Regular Check-ups

Throughout your Invisalign treatment, you’ll visit your orthodontist every 6-8 weeks to monitor progress and make any necessary adjustments. 

While Invisalign aligners are designed for comfort and convenience, it’s important to follow the instructions carefully, wearing your aligners for at least 20-22 hours per day for optimal results.

Benefits of Using Invisalign for Underbites Treatment

Invisalign offers several advantages over traditional braces, making it an appealing option for many individuals with underbites.

Aesthetic Appeal

One of the main reasons people opt for Invisalign is the clear, discreet appearance of the aligners. 

Unlike trational metal braces, Invisalign aligners are almost invisible when worn, making them an ideal choice for adults or teenagers who want a more subtle orthodontic treatment.

Comfort and Convenience

Invisalign aligners are made from smooth plastic, meaning they are far more comfortable than metal braces, which can cause irritation to the gums and mouth. 

Additionally, the aligners are removable, making it easier to maintain good oral hygiene and allowing you to eat and drink without restrictions.

Effective for Mild to Moderate Underbites

Invisalign is often effective for treating mild to moderate underbites, especially in cases where the misalignment involves only the teeth, rather than the jaw itself. Invisalign can help realign the teeth and improve the bite over time.

What to Expect During Your Invisalign Treatment for Underbite

If you decide to move forward with Invisalign for your underbite, here’s what you can expect during the treatment process.

Initial Consultation

The first step is a consultation with your orthodontist, who will assess the severity of your underbite and determine if Invisalign is a good treatment option. 

This appointment may involve taking X-rays, photographs, and impressions of your teeth to create your customised treatment plan.

Wearing Your Aligners

Once your aligners are ready, you’ll begin wearing them according to your orthodontist’s instructions. 

You'll need to wear the aligners for most of the day, only removing them for eating, drinking, and brushing your teeth. 

It's important to wear them consistently to ensure the treatment works as planned.

Tracking Progress

Throughout your treatment, you’ll have regular check-ups with your orthodontist to monitor your progress. 

These visits will help ensure that the aligners are moving your teeth as planned and that the underbite is being addressed effectively.

Final Stages

Once you’ve completed the series of aligners, your orthodontist will assess your final results. 

If necessary, you may need to wear retainers to help maintain the new position of your teeth and prevent relapse.

Frequently Asked Questions 

1. Can Invisalign fix a severe underbite?

Invisalign is effective for mild to moderate underbites. However, for severe underbites involving significant jaw misalignment, additional treatments like surgery or traditional braces may be necessary.

2. How long does Invisalign treatment take for an underbite?

The length of treatment varies depending on the severity of the underbite. On average, Invisalign treatment for an underbite can take anywhere from 12 to 24 months, though some cases may take longer.

3. Can I eat with Invisalign aligners in?

No, Invisalign aligners should be removed before eating or drinking anything other than water. This helps to prevent food particles from getting trapped in the aligners and affecting the treatment.

Conclusion

Invisalign can be an effective and discreet option for correcting mild to moderate underbites. 

The aligners gradually shift the teeth into proper alignment, improving both function and appearance. 

However, for severe cases, where jaw misalignment is a factor, other treatments such as braces or surgery may be necessary. 

If you're considering Invisalign for your underbite, consult with an orthodontist to discuss your options and develop a treatment plan that works for you.
