How Invisalign Works to Straighten Teeth

At Four Corner Dental Group, we understand that each smile is unique, which is why the duration of your Invisalign treatment will depend on several factors, including the complexity of your case, your personalized treatment plan, and your dedication to wearing your aligners as instructed. For most of our patients, Invisalign treatment typically takes between 12 and 18 months to achieve beautifully straightened teeth.

If your alignment issues are mild, such as slight crowding or small gaps, you might begin seeing results in as little as six months. However, for more complex cases involving significant bite concerns or severe misalignment, treatment may extend up to two years or a little longer.
During your comprehensive Invisalign consultation at Four Corner Dental Group, our skilled team will thoroughly assess your teeth and bite, using advanced digital imaging technology to create a fully customized treatment plan. This plan will include a step-by-step projection of your tooth movement and an estimated timeline for your results.

To ensure the treatment progresses efficiently, it’s essential to wear your Invisalign aligners for 20 to 22 hours per day and switch to the next set of aligners as directed by your Four Corner Dental Group clinician. Regular check-ups at our practice will also help ensure your treatment stays on track.

While most patients at Four Corner Dental Group complete their Invisalign treatment in approximately 12 to 18 months, you’ll receive a detailed and personalized timeline following your initial assessment, and we’ll be here to support you every step of the way to help you achieve your perfect smile.

Yes, Invisalign is highly effective at closing both small and large gaps, a condition medically known as diastema. Gaps can occur for several reasons, including a mismatch between the size of the jaw bone and the size of the teeth, or habits like tongue thrusting.

For smaller gaps, the aligners work by applying gentle, horizontal pressure to pull the teeth together. For larger spaces, Pete Higgins, DDS utilizes sophisticated 3D planning software to ensure the teeth move in a synchronized manner, preventing the creation of new gaps elsewhere in the mouth. In some complex cases involving very large spaces, we may use “attachments”—small, tooth-colored bumps bonded to the teeth—to give the aligners extra leverage to shift the teeth more predictably.

The timeline for closing spaces depends largely on the total distance the teeth need to travel. On average, most patients at Four Corners Dental Group complete their treatment within 10 to 18 months.

Minor gaps, such as a small space between the two upper front teeth, can sometimes be closed in as little as 4 to 6 months. However, if there are multiple gaps throughout the upper and lower arches, the process takes longer because the entire “arch” of the mouth must be reshaped. Because Invisalign moves teeth in increments of about 0.25mm per aligner tray, consistency is key; wearing your aligners for at least 22 hours a day ensures you hit your milestones on time.

The risk of gaps reopening—known as orthodontic relapse—is a common concern. Teeth have a natural tendency to want to return to their original positions, especially in cases where large gaps were closed. The ligaments holding the teeth in place take time to solidify in their new arrangement.

To ensure your results are permanent, wearing a retainer is non-negotiable. Pete Higgins, DDS typically provides custom-fitted Vivera retainers once the active phase of treatment is finished. Initially, these may need to be worn both day and night, eventually transitioning to night-only wear. This constant support prevents the “drifting” that causes spaces to reappear, protecting your investment in your smile.

Invisalign is particularly successful at closing gaps in the front teeth, which are often the biggest source of self-consciousness for patients. Because the front teeth have single roots, they often respond very quickly to the controlled pressure of clear aligners.

Beyond aesthetics, closing front-of-mouth gaps is beneficial for your oral health. Large spaces can lead to “food impaction,” where debris gets trapped against the gums, potentially causing localized inflammation or gingivitis. By bringing these teeth into proper alignment, Invisalign makes it easier to maintain healthy gum tissue and creates a more harmonious “smile line” that complements your facial features.

At Four Corners Dental Group, we believe that every patient deserves a smile they are proud to show off. Pete Higgins, DDS takes a comprehensive approach to spacing issues, looking beyond the gaps to ensure your overall bite (occlusion) is functional and healthy. Our practice uses the scanner to create a high-resolution 3D map of your teeth, allowing you to see a digital preview of your closed-gap smile before you even start. We prioritize patient comfort and clear communication, ensuring you understand every step of your journey from the first tray to the final retainer. Our goal is to provide a seamless, stress-free experience that results in a perfectly spaced, radiant smile.
