Can Invisalign fix overbites and underbites?

What are overbites and underbites?

When your teeth and jaws don’t align properly, dental professionals call this a malocclusion. Two common types are overbites and underbites:

• Overbite: Occurs when your upper front teeth significantly overlap your lower front teeth. A small overlap is normal, but when it’s excessive, it can lead to jaw pain, uneven wear, and gum issues.
• Underbite: Happens when your lower front teeth extend past your upper teeth. This can make chewing and speaking more difficult and may affect your facial appearance.

Both conditions are more than cosmetic; they can significantly impact your long-term oral health.

How does Invisalign work compared with braces?

If you’re exploring orthodontic treatment options, you’ve probably heard of Invisalign and traditional braces. Both straighten teeth, but they work in different ways.

• Invisalign: Uses a series of clear, removable aligners that gradually shift your teeth into place. Because they’re custom-made and nearly invisible, they’re a discreet choice for many adults and teens. You can remove them to eat, brush, and floss, which helps make maintaining oral hygiene easier during treatment.
• Braces: Use brackets and wires that stay fixed to your teeth throughout treatment. They’re highly effective for complex cases involving significant jaw movement or skeletal adjustments.

When comparing Invisalign vs braces, it’s not about which is newer, it’s about which is better suited to your unique bite and alignment needs. For many patients with mild or moderate misalignment, clear aligners offer a comfortable, modern alternative to braces.

Can Invisalign correct overbites?

In many cases, yes. Invisalign can effectively correct mild to moderate overbites by applying gentle, controlled pressure that shifts the upper front teeth slightly backward and the lower teeth forward, helping reduce excessive overlap.

For more advanced cases, your dentist may add small attachments or elastics to enhance movement and improve jaw alignment. These additions to the aligners help them achieve results that once required braces.

If you have a mild overbite caused primarily by tooth positioning rather than a skeletal issue, Invisalign can be a highly effective and comfortable solution for bite correction.

Can Invisalign correct underbites?

Invisalign can also correct many underbites. As with overbites, Invisalign clear aligners are most effective for treating underbites caused by dental misalignment rather than skeletal structure. The aligners gently move the lower teeth backward and the upper teeth forward to create a more balanced bite.

For severe underbites caused by jaw position, additional orthodontic treatment or jaw surgery may be necessary. Your provider will take a 3D scan of your teeth and bite to determine whether aligners alone can achieve the correction you need.

In general, clear aligners for malocclusion work best when the jawbones are properly aligned but the teeth need repositioning.

How long does Invisalign take to correct an overbite or underbite?

So, how long does Invisalign take for an overbite or underbite correction? The answer depends on the severity of your condition and how consistently you wear your aligners.

Mild to moderate bite issues typically take 12–18 months to correct. More complex cases, especially those involving the jaw, can take up to 2–3 years.

Wearing your aligners as directed, about 20–22 hours daily, and attending regular check-ins with your dentist or orthodontist will help keep your treatment on track and ensure the best results.

When might braces or other treatments be needed instead?

While Invisalign can be an effective treatment for many overbite and underbite cases, it isn’t ideal for everyone. Severe skeletal misalignment, significant jaw discrepancies, or certain types of tooth movement may respond better to traditional braces or a combination of orthodontic methods.

Your dentist might recommend other approaches such as jaw surgery, expanders, or additional appliances to support proper correction. If you find it difficult to wear aligners consistently, braces might provide more reliable progress since they stay fixed in place.

A comprehensive exam and digital imaging will help your dentist determine which treatment option is best for your smile.

Is Invisalign the right choice for your bite correction?

Choosing the right orthodontic treatment depends on several factors. During your consultation, your dentist will evaluate whether your bite issue is due to tooth position or jaw structure. You’ll also discuss treatment length, daily wear expectations, and the pros and cons of Invisalign vs braces for your specific goals.

When planned by an experienced provider, Invisalign offers a modern, discreet, and comfortable way to improve your smile and your bite. For many adults and teens, it’s an excellent path to long-term oral health without the visibility of traditional braces.

FAQs about Invisalign for overbites and underbites

Can Invisalign really fix an overbite?

Yes. Invisalign can correct most mild to moderate overbites by gradually shifting teeth into better alignment. More complex cases may need attachments or elastics for best results.

Can Invisalign fix an underbite?

In many cases, yes, especially when the issue is caused by tooth position rather than jaw structure. Severe underbites involving the jaw may require braces or surgery.

How long does Invisalign take to fix an overbite or underbite?

Treatment time varies by case. Most people see results within 12 to 18 months, though minor adjustments can take as little as 6 months and complex cases may take up to 3 years.

Which is better for bite correction, Invisalign or braces?

Both are effective. Invisalign is ideal for mild to moderate alignment issues and offers a nearly invisible option. Braces are often recommended for more complex bite or jaw problems.

Is Invisalign treatment painful?

Invisalign is not usually painful, but mild pressure or soreness can occur when switching to a new set of aligners. This feeling typically fades within a few days as your mouth adjusts.
