This is one of the first questions people ask at a consultation. Before committing to any orthodontic treatment, knowing roughly how long it takes matters. It affects planning, budgeting, and, honestly, your motivation to get started.
The short answer is that both Invisalign and braces work on the same biological process and take broadly similar amounts of time for comparable cases. But there are real differences in how that time breaks down, what affects it, and what “seeing results” actually means at different stages.
Here’s what Dr. Amani Morra at Dream Orthodontics wants Surrey patients to understand before making the comparison.
Why There’s No Single Answer to This Question
Treatment length depends on the case, not the appliance. A mild crowding issue treated with Invisalign in Surrey will finish faster than a complex bite correction treated with braces. Comparing the two without specifying the case is a bit like comparing how long it takes to drive somewhere without specifying the destination.
That said, there are general patterns worth knowing.
How Long Does Invisalign Typically Take
For mild to moderate cases, Invisalign in Surrey often runs between 6 and 18 months. More complex cases involving significant bite correction can extend to 24 months or occasionally beyond.
Invisalign Lite, a shorter series designed for minor alignment cases, can be completed in as little as 3 to 6 months. This isn’t suitable for everyone, but for patients with limited crowding or spacing issues and no significant bite problems, it’s a faster path.
Several factors affect where on that range you land:
- Case complexity. Rotations, vertical tooth movements, and bite corrections take longer than simple spacing or crowding
- Wear time. Aligners need 20 to 22 hours per day to move teeth on schedule. Patients who consistently fall short of that extend their own timeline
- Whether refinements are needed. Some patients need additional aligner sets at the end to finish what the original series started. This adds weeks or months, depending on how much movement remains
When do you start seeing changes? Most Invisalign patients notice visible improvement in tooth position within the first two to three months, though this varies by case.
How Long Braces Typically Take
Traditional metal braces and clear braces in Surrey typically run between 18 and 24 months for most cases. Complex cases can run longer. Simpler cases sometimes finish earlier.
Braces have a slight clinical advantage for certain movements, particularly large rotations and vertical adjustments. Because they’re fixed to the teeth 24 hours a day and can’t be removed, force is applied continuously. This is part of why braces remain the go-to for more complicated bite corrections.
Visible changes with braces also tend to show up within the first couple of months for most patients, particularly in the front teeth, where movement is most noticeable early on.
The Real Differences That Affect Your Timeline
The appliance itself is only one variable. A few other factors matter more than most people expect.
Case complexity
This is the most significant driver of treatment length. A patient with mild crowding and no bite issues will finish treatment faster than a patient with a significant underbite or severely rotated teeth, regardless of whether they choose Invisalign or braces in Surrey.
Patient compliance
This applies more directly to Invisalign. Braces can’t be removed, so the force is always working. With aligners, the patient controls how many hours per day they’re worn. Patients who remove them frequently for convenience and lose track of hours often need additional refinements or extended treatment.
Missed appointments
Both braces and Invisalign require regular check-in appointments. With braces, those visits are when the wire is adjusted, and treatment progresses. With Invisalign, the orthodontist monitors tooth tracking and decides when to advance the series. Consistently missed or rescheduled appointments slow progress for both.
Biology
Some patients’ teeth and bone simply respond more slowly than others. Age plays a role, as does bone density and individual variation in how the periodontal ligament responds to sustained pressure. This isn’t something patients can control, but it’s something Dr. Morra accounts for when estimating timelines.
Which Option Finishes Faster?
For straightforward cases, the timelines are genuinely comparable. A patient with mild crowding might finish Invisalign in 12 months and braces in 14, or vice versa. The difference is not dramatic enough to make it the deciding factor for most people.
For complex cases, braces often have a clinical advantage in total treatment efficiency. For very mild cases, shorter Invisalign series can finish faster than conventional braces.
If you’re weighing up both options, the more useful comparison is in the experience during treatment rather than the endpoint. For a full breakdown, Clear Braces vs Invisalign covers the day-to-day differences in more detail.
What Happens After Treatment Ends
Regardless of which option you choose, retention is what keeps the results in place. Teeth have a natural tendency to shift back toward their original positions once active treatment ends. A retainer worn as directed by Dr. Morra is what prevents that from happening.
Most patients are given retainers to wear full-time initially, then transition to nights only. How long you wear them after treatment is, in a real sense, as important as the treatment itself.
