We’ve straightened over 500 cases using Invisalign at our dental practices in Chandler’s Ford & Lymington. The average duration is between 6 and 12 months for moderate-to-severe cases.
Faster, straighter smiles in as little as 7 weeks
Each case of Invisalign is unique, and treatment duration varies depending on your individual circumstances. However, most patients can expect results within a few months to a year.
- 7 weeks: Treating orthodontic relapse.
- 3 months: Minor crowding & small gaps.
- 3-6 months: Mild alignment (crowding & spacing).
- 6-9 months: Moderate crowding, rotations & mild bites.
- 9-12 months: More complex alignment, like overbites.
- 12+ months: Severe crowding or major bite correction.

How long each version of Invisalign typically takes
Invisalign is not one standard course of treatment. It uses different versions, calculated by the number of aligners required to straighten your orthodontic problem, which affects your overall treatment timeline.
This is because not all orthodontic cases require the same level of tooth movement or treatment duration.
Options like Invisalign Express, Lite, Moderate and Comprehensive are designed to match the varying and increasing levels of complexity.
Hence, Invisalign Express is the faster system because it targets only very minor crowding or spacing issues.
Patients do not get to select the system they prefer; instead, our Invisalign dentists will recommend the right system based on their specific needs after a detailed assessment of their teeth, bite, and goals.
Average Invisalign treatment times explained:
| Invisalign plan | Cases best for | Typical timeline | Typical number of aligners |
|---|---|---|---|
| Invisalign Express | Very minor crowding, small gaps, and slight relapse cases | Up to 3 months | 5-10 aligners |
| Invisalign Lite | Mild crowding, spacing, and minor rotations | 3-6 months | 10-14 aligners |
| Invisalign Moderate | Moderate crowding, spacing, mild bite correction | 6-9 months | 14-26 aligners |
| Invisalign Comprehensive (Full) | Complex crowding, bite issues, and significant movement | 9-12+ months | Unlimited aligners |
Most adult patients using Invisalign start to notice visible changes within the first 6-8 weeks.
Compare timelines
We mean it when we say every smile is different, and with braces or aligners, it’s not a one-size-fits-all approach. For mild issues like small gaps or slight crowding, Invisalign is often the fastest and most comfortable option, delivering noticeable results in just a few months.
It’s only when cases become more complex, like severe bite issues, that Invisalign might pose some limitations compared to braces. For more complex orthodontic problems, traditional braces might offer the most control for complex tooth movement over longer periods.
Invisalign timeline vs braces
| Smile problem | Invisalign approach | Braces approach | Typical timeline |
|---|---|---|---|
| Mild crowding / small gaps | Highly effective with clear aligners (Express/Lite) | Effective but often over-treatment for simple cases | 3–6 months (Invisalign faster) |
| Slight crooked teeth / minor rotations | Very effective with predictable digital planning | Effective but less discreet | 3–6 months (similar, Invisalign is more comfortable) |
| Moderate crowding/spacing | Highly effective with Moderate/Comprehensive plans | Highly effective, slightly more rigid control | 6–12 months (similar outcomes) |
| Mild bite issues (overbite/underbite) | Effective in many cases with attachments & refinements | Often slightly more powerful for complex bite control | 6–12 months (case dependent) |
| Severe crowding / complex bite correction | Effective in selected cases, may need refinements | Gold standard for complex movement | 12–24+ months (braces often preferred) |
| Retention (both treatments) | Retainers to maintain results | Retainers to maintain results | Long-term (nightly wear) |
The Invisalign journey at The Smiles Studios
Your Invisalign journey with The Smiles Studios is simple, fast and planned for precision from the start.
In the first phase of the treatment, we use advanced 3D scanning to map your teeth and show you a preview of your future smile before treatment begins. This will also create your custom aligners, how many you’ll need and how long you need to wear them.
Once your aligners arrive, you’ll need to wear and change them every 7-14 days as your teeth gradually move into their pre-planned positions.
In some cases, small refinements may be required to perfect the final results, and your treatment will conclude with custom retainers to protect your smile’s position over the long term.
Treatment stages: What to expect month-to-month
You’ll begin to see results within weeks and attend regular review appointments to monitor your progress.
| Stage | Timeline | What happens |
|---|---|---|
| Consultation & planning | Month 1 | 3D scan, smile preview, custom plan, aligners ordered |
| Start aligners | Months 2–3 | Wear aligners, change every 7–14 days |
| Visible movement | Months 4–6 | Teeth start straightening, regular check-ups |
| Refinements (if needed) | Months 6–12 | Extra aligners for fine-tuning results |
| Retention | Final stage | Retainers fitted to maintain smile |

Many thanks ☺️Posted on Google Nicola BakerTrustindex verifies that the original source of the review is Google. I’ve been having treatment done and today I was in for my Implant operation. I was incredibly nervous but I have to say it was fine it was actually less uncomfortable than some of the other work I have had done. Dr Mahesh Nagpal was great and put me at ease with what was about to happen, and making sure I was ok. Overall so far the treatment and communication I’ve had done, and the results I’ve seen are fantastic. I would highly recommend Smiles Dental surgery all the staff have been great.Posted on Google Olivia MalpiediTrustindex verifies that the original source of the review is Google.
