If you are choosing between Invisalign and braces for your orthodontic treatment, speed is usually one of the first questions that comes up. Invisalign can be quicker in many mild-to-moderate cases compared to standard metal braces, but it is not faster for everyone.
At Radiant Smiles Perth, we believe that treatment time depends on the complexity of the tooth movement, the type of bite correction needed, and – with aligners especially – how consistently they are worn. This guide offers a comparison between Invisalign and braces to answer the question of whether Invisalign is quicker than braces.
Is Invisalign quicker than braces | The quick answer
Timeframes are roughly 6 to 18 months for Invisalign and anywhere between 18 months to 3 years for braces. However, that does not mean Invisalign wins in every case. A scientific article by The Angle Orthodontist found that, in patients with simple Class I malocclusions, Invisalign treatment took 4.8 months longer than traditional braces, even though the final occlusal results were similar.
Invisalign vs. braces: a side-by-side comparison
The decision is not only about speed. It is also about suitability, predictability, and whether the patient is a strong candidate for removable aligners.
| Scenario | Invisalign will be quicker | Braces will be quicker |
|---|---|---|
| Case type | Mild-to-moderate crowding | Significant bite correction |
| Spacing and alignment | Mild spacing | Severe misalignment |
| Tooth movement | Predictable tooth movement that can be mapped efficiently with digital planning. | Rotated teeth or more complex movement |
| Patient suitability | Patients who will wear aligners as directed. | Patients unlikely to wear aligners consistently. |
| Treatment progression | Cases likely to follow the original aligner plan smoothly. | Cases where refinements could prolong aligner treatment. |
Where Invisalign can be quicker
Invisalign has a clear speed advantage in cases where tooth movement is predictable and the patient is well-suited to aligner therapy. Three factors explain why:
More efficient for straightforward cases
Invisalign is often quicker in mild-to-moderate cases because tooth movement is more predictable and treatment can be planned efficiently from the start. When the case is not overly complex, aligners can deliver a streamlined treatment process with fewer variables.
Digital planning supports precise movement
Invisalign treatment is based on digital scans and staged planning, allowing each aligner to move the teeth incrementally toward the desired position. This can make treatment highly efficient when the movements are well suited to aligner therapy.
The removable design can support consistency
Because aligners are removable, patients can eat comfortably, and brush and floss their teeth normally. While this does not make treatment biologically faster on its own, it can make the process easier to manage for patients who are committed to wearing them properly.
Where braces can be quicker
Braces have the upper hand in cases that involve more demanding tooth movement or patients who are unlikely to wear aligners consistently. Here is where that advantage shows up:
Braces work continuously
Braces are fixed in place, meaning they work around the clock without needing any action from the patient. Invisalign aligners must be worn for 20 to 22 hours a day, and any shortfall in wear time can delay progress.
Better suited to complex movement
Braces can be quicker and more effective for severe misalignment, rotated teeth, and significant bite correction. While Invisalign can be very efficient for simpler cases, braces often have the advantage once treatment becomes more mechanically demanding.
What affects treatment speed?
Treatment time is rarely determined by the appliance alone. The following factors have the biggest influence on how long orthodontic treatment takes, regardless of whether you choose Invisalign or braces.
1. Case complexity
This is the biggest factor. Invisalign is better suited for mild crowding and spacing cases, while braces are better suited for more difficult bite corrections or severe alignment issues.
2. Wear time
Invisalign is only as fast as the patient is consistent. If the aligners are not worn for the recommended 20 to 22 hours per day, treatment can slow down significantly.
3. Refinements
Some Invisalign cases need refinements when teeth do not move exactly as planned, or when extra adjustment is needed to achieve the final result. These additional stages can add weeks or months to the treatment plan.
4. Type of tooth movement
Not all movements respond equally to aligners. More complex corrections, including major bite changes or difficult rotations, may be completed more efficiently with braces.

Invisalign FAQs
Is Invisalign more comfortable than braces?
Invisalign is often considered more comfortable because it does not use brackets or wires. That said, both Invisalign and braces can cause some discomfort as teeth move.
Can Invisalign work as well as braces?
Yes, in many cases it can. Invisalign can achieve excellent results for a wide range of mild-to-moderate orthodontic concerns, while braces may be more effective for more complex treatment needs.
What happens if you do not wear Invisalign long enough each day?
Treatment can slow down if you do not wear your Invisalign long enough each day. Invisalign needs to be worn for 20 to 22 hours per day, and inconsistent wear can delay tooth movement and extend the overall timeline.
Why do some Invisalign cases need refinements?
Refinements are needed when teeth do not track exactly as planned or when additional movement is required to achieve the intended result. This is a normal part of some Invisalign cases and can extend treatment time.
Is Invisalign always better for adults?
Not always. Many adults prefer Invisalign because it is discreet and removable, but braces may still be the better option when more complex tooth movement or bite correction is required.
