Can Invisalign Fix an Underbite? Cost, Results & FAQs

Invisalign can fix an underbite in many cases, even for adults.

An underbite is when your lower teeth stick out in front of your upper teeth. This can impact your bite, chewing, speech, and even your facial appearance. Lots of people ask if clear aligners like Invisalign can fix an underbite instead of using metal braces or having surgery. In many cases, the answer is yes, but it depends on how serious the underbite is.

Let’s talk about how Invisalign works for underbites, how much it costs, and other questions people usually ask.

How Does Invisalign Fix an Underbite?

Invisalign uses clear, plastic trays that fit snugly over your teeth. These trays gently guide your teeth into better positions little by little.

Here’s how it works for an underbite:

• Invisalign can move your lower teeth backward or bring your upper teeth forward.
  
• It helps close gaps or fix crowded teeth that may cause an underbite.
  
• The aligners are custom-made for your mouth using 3D scans for a precise fit.
  

For mild to moderate underbites, Invisalign often does a great job. But if your underbite is more severe and caused by how your jaws are shaped, you might still need surgery along with Invisalign treatment.

Think of it like this: if your lower teeth stick out a few millimeters past your upper teeth, Invisalign trays can slowly move those bottom teeth back so they align properly. 

In fact, a study in the Journal of Clinical Orthodontics found that clear aligners successfully corrected underbites (Class III malocclusions) in about 78% of cases.

Can Invisalign Fix an Underbite in Adults?

Yes. Invisalign can fix underbite in adults as well as teens. Adult bone structures are harder to move than children’s, so treatment might take longer. But many adults have great success with Invisalign.

Many adults go for Invisalign because the clear trays are hardly noticeable. You can take them out to eat or brush your teeth, and they are usually more comfortable than metal braces

A wider survey of 298 adult patients showed 84.9% reported being “very satisfied” or “satisfied” overall with their Invisalign treatment, specifically citing better tooth alignment and boosted confidence.

Invisalign Underbite Before and After

Many patients see big changes after using Invisalign for an underbite. Before treatment, the lower teeth often push out, giving the chin a stronger look. After treatment:

• The teeth line up correctly.
• The bite feels better.
• The face profile can look softer.

How Long Does Invisalign Take to Fix an Underbite?

The time it takes for Invisalign to correct an underbite depends on:

• How severe your underbite is.
• How well you wear your aligners.
• If you need other dental work first.

Mild underbites might take around 8 to 12 months. Moderate underbites might take about 12 to 18 months to fix with Invisalign. Very severe cases could take longer or might need more than just aligners to fully correct. If you have gaps between your teeth, closing them could take around 6 to 12 months. 

To keep your treatment on schedule, wear your aligners for 20 to 22 hours daily, removing them only for meals, drinks other than water, and brushing your teeth. 

Can Invisalign Fix Overbite and Crossbite Too?

Invisalign can also fix other bite problems, like:

• Overbite, where your top teeth overlap your bottom teeth too much
• Crossbite, where some upper teeth bite inside the lower ones.

Aligners move teeth bit by bit into a better bite. However, like underbites, very severe cases of overbite or crossbite might need extra treatments or surgery.

How Much Does Invisalign Cost for an Underbite?

Invisalign cost for underbite treatment varies. In the U.S., it usually costs between $3,000 and $8,000. Factors that affect cost include:

• How severe your underbite is.
• How long does your treatment last?
• Your location and orthodontist’s fees.
• Whether you have dental insurance.

Palm Valley Orthodontics in Scottsdale offer payment plans to help make Invisalign easier on your budget. 

Insurance might cover part of the cost if your treatment is medically needed. Plus, you can often use Flexible Spending Accounts (FSAs) or Health Savings Accounts (HSAs) to help pay for Invisalign.

Is Invisalign Better Than Braces for an Underbite?

For some people, yes. For others, braces may still be the better choice. It depends on your underbite’s severity and your orthodontist’s opinion.

Advantages of Invisalign:

• Clear and discreet.
• Removable for eating and cleaning.
• Often more comfortable.

Advantages of Braces:

• Better for severe or complex jaw problems.
• Sometimes, work faster for serious cases.

Your orthodontist will check your bite and recommend the best option.

Can I Fix My Underbite Without Surgery?

Many underbites can be fixed without surgery, especially if they’re mild to moderate. Invisalign or braces alone might be enough. But if the jawbones themselves are too far apart, surgery could be needed to move the jaws into place.

Only an orthodontist or oral surgeon can tell you for sure after examining your teeth and jaw.

Final Thoughts
