Patients often arrive at a consultation having done considerable reading about Invisalign but with a fairly vague sense of what the process actually involves from the first appointment to the final aligner.
That gap between general awareness and practical understanding is worth closing before you commit. What follows is how treatment actually works at Coniston Dental, covering the clinical steps, the technology, and the things that tend to catch people out.
Step One: Assessment and Digital Planning
The process begins with a thorough clinical examination. We assess your teeth, gums, and bite, and take a full medical and dental history. Invisalign is not appropriate for everyone, and identifying any existing issues before treatment starts is important. Active gum disease, for instance, needs to be under control before orthodontic movement begins.
If Invisalign looks like a suitable route, we take a digital scan of your teeth using an intraoral scanner. This replaces traditional impression putty with a precise three-dimensional model, and it’s considerably more comfortable. The scan data is sent to Invisalign’s clinical team, who use it to build a ClinCheck simulation: a step-by-step digital representation of how your teeth will move across the course of treatment.
Worth knowing: you review that simulation at the planning stage and can discuss adjustments before any aligners are manufactured.
How the Aligners Move Your Teeth
Each aligner in the series is fractionally different from the one before it. When you put in a new tray, it doesn’t fit perfectly over your teeth straightaway; it’s slightly ahead of where your teeth currently are. That gentle discrepancy is what creates the force that moves the teeth.
The British Orthodontic Society describes it clearly: each appliance moves the teeth a small distance towards the intended position before moving on to the next in the series until the final result is achieved. Each tray is worn for approximately one to two weeks, then you progress to the next.
And that incremental logic is precisely what makes the system work. No dramatic forces, no sudden adjustments. Consistent, controlled movement over an extended period.
Attachments and Auxiliaries
Some cases require more than the aligners alone. Small composite resin buttons, called attachments, are bonded onto specific teeth to give the aligner leverage for particular movements. Rotations, extrusions, and torque corrections often need them. The attachments are tooth-coloured and match closely; they’re rarely noticeable except on close inspection.
Interproximal reduction is another technique used in some cases. This involves very carefully reducing a small amount of enamel between adjacent teeth to create space. It’s used instead of extractions in certain types of crowding, and the amounts removed are minimal.
Not every case needs these additions. Many straightforward cases proceed with aligners alone.
Wearing the Aligners Day to Day
The instruction is consistent: 20 to 22 hours per day, every day. The aligners come out for eating, drinking anything other than plain water, and oral hygiene. That’s it. Most patients find this workable once they’ve adjusted to the routine, but the adjustment period is real.
In our experience, the first two to three weeks are the most demanding in terms of adapting to life with aligners. Speech can feel slightly affected early on; some patients find removing the trays awkward at first. Both of those things settle. But the clinical outcome is directly tied to wearing time, and we ask patients to be honest with themselves about whether that commitment is realistic before starting.
Oral hygiene matters too. Because the aligners sit over the teeth, any food or sugar trapped between the tray and the tooth surface creates a risk. Brushing and cleaning between teeth before reinserting the aligner is not optional.
Review Appointments
Treatment isn’t something you manage alone at home. Review appointments at Coniston Dental typically occur every six to eight weeks. At each visit, we check that your teeth are tracking correctly. If they’re not, there are refinement options available, but catching any deviation early is preferable.
If you progress well, you move through your aligner sequences and we confirm the timeline. If adjustments are needed, we communicate that clearly rather than allowing expectations to drift.
What Happens at the End of Treatment
When you reach your final aligner, the active phase of treatment is complete. But the teeth won’t stay in position on their own. Retention is the mechanism that preserves the outcome, and it’s a permanent part of the process. The NHS orthodontic treatments guidance is clear that retainers are required after any course of orthodontic treatment to maintain the corrected position of the teeth.
We fit retainers at the end of Invisalign treatment. Options include removable clear retainers worn at night, fixed bonded wires behind the front teeth, or a combination of both. Which is most appropriate depends on your case and your preferences.
Starting the Conversation
Understanding the process is one thing; knowing whether it’s right for your specific teeth is another. Coniston Dental Practice offers dedicated Invisalign consultations where our team can map out exactly what treatment would look like for you, including timelines and what to realistically expect at each stage.
