How Long Does It Take to Correct an Underbite with Invisalign?

An underbite can impact both oral function and appearance, leading many to seek correction without traditional metal braces. Invisalign® provides a discreet, comfortable solution designed to guide teeth into proper alignment. The duration of treatment varies by individual, making it essential to understand the process to set informed and realistic expectations.

How Invisalign Works for an Underbite

Invisalign uses a number of custom-made, clear aligners that shift teeth a little at a time. Each set is worn for about one to two weeks before moving to the next. Aligners place gentle pressure in planned directions, guiding teeth into the correct position.

For an underbite, the aligners may move the lower teeth back, the upper teeth forward, or both. This is done through small, steady movements. Sometimes, tiny tooth-colored shapes are added to help grip the aligners and direct movement.

Key points to remember:

• You wear aligners for 20–22 hours each day
• They come out only for eating, drinking, brushing, and flossing.
• Progress is monitored at regular visits with your provider.

Factors That Affect Treatment Time

Every underbite is different, and so is the time it takes to correct it. Your timeline depends on:

• Severity of the underbite – A mild case may take months; a severe one can take longer
• Age – Teeth in younger patients often respond faster to movement
• Jaw position – If bone structure plays a big role, other treatments may be needed along with Invisalign
• Commitment – Wearing aligners as directed is crucial.
• Dental health – Healthy gums and teeth respond better to treatment

If you’re looking to get Invisalign® near you, ask for an evaluation to see where your case falls in this range. This helps set a realistic expectation from the start.

Average Timeline for Underbite Correction with Invisalign

Most mild to moderate underbites can be improved within 12 to 18 months. Patients from the area, who have gotten Invisalign® in Spirit Lake, often notice early changes in just a few months, depending on their commitment and case complexity.

Your provider will create a digital treatment plan that shows the expected progress at each stage. This preview helps you see the estimated timeline before starting.

Quick reference:

• Mild cases – 6 to 12 months
• Moderate cases – 12 to 18 months
• Complex cases – 18 to 24 months or longer

While these numbers are common, your dedication to wearing the aligners is the single biggest factor in staying on track.

What to Expect During Your Invisalign Journey

The process begins with a consultation, where your provider checks your teeth, takes scans, and designs your plan. Once your aligners arrive, you’ll get the first few sets along with instructions.

Typical steps include:

1. Initial fitting – You’ll learn how to insert and remove your aligners
2. Daily wear – Keep them in for the recommended hours
3. Switching aligners – Usually every 1–2 weeks
4. Check-ins – Short appointments to monitor progress and give you new sets
5. Attachments or elastics – Sometimes used for complex movements

In the first days of a new set, you may feel pressure as teeth begin to shift. This eases after a short time and signals that the aligners are doing their job.

If you need a dentist near you for these check-ins, choose one with experience in orthodontic treatment. This ensures your case gets the right attention at every stage.

Tips to Stay on Track and See Faster Results

You have more control over your timeline than you might think. Follow these tips to keep your treatment moving:

• Wear them as directed – 20–22 hours daily is not a suggestion; it’s a requirement.
• Change aligners on schedule – Delays in switching can slow progress
• Maintain oral hygiene – Clean teeth and healthy gums support better movement
• Store aligners safely – Lost aligners mean waiting for replacements, which can add weeks.
• Follow dietary guidelines – Avoid chewing with aligners in place.
• Ask about refinements – Minor adjustments toward the end can perfect your results.

A clear plan plus daily discipline can help you finish sooner and with the smile you want.
