What Is Invisalign and How Does It Work

Invisalign is a clear aligner system that moves teeth using a sequence of removable trays instead of fixed brackets and wires. Each tray is made to your own measurements from a digital scan of your mouth.

You wear each aligner for one to two weeks before moving to the next in the series. Every tray applies gentle pressure to move specific teeth by around 0.2 to 0.3mm, so the sequence gradually works your teeth towards their planned final position.

Full technical information on the system is published on the official Invisalign website.

How Invisalign Differs From Fixed Braces

Fixed braces are bonded to your teeth for the whole of treatment. Invisalign aligners are removable, so you take them out to eat, drink anything other than water, and clean your teeth normally.

That flexibility comes with responsibility. Aligners only move teeth while they are being worn, so treatment depends on you wearing them for 20 to 22 hours a day. Small tooth-coloured attachments are usually bonded to some teeth to help the aligners grip and control movement.

Your Invisalign Treatment, Step by Step

Step 1: Assessment and 3D Scan

We check your teeth, gums and bite, then take a 3D digital scan. Any decay or gum disease is treated before aligner therapy begins.

Step 2: Your Digital Plan

We map every stage of tooth movement and show you a preview of your projected result, alongside a fixed quotation, before treatment begins.

Step 3: Wearing Your Aligners

You change to a new aligner every one to two weeks and attend review appointments so we can check progress against the plan.

Step 4: Retention

Once your teeth are in position, we fit a hidden wire retainer and provide night-time removable retainers, both included in your price.

How does it work?

We begin by taking a 3D digital scan of your teeth, allowing us to plan each stage of your smile transformation before treatment even starts. Once your aligners are created, you’ll switch to a new set every 1–2 weeks, each one moving your teeth closer to their planned position.

✅ No metal, tightening or visible brackets
✅ Each aligner moves teeth by 0.2–0.3mm
✅ Worn for 20–22 hours a day
✅ Removable for meals, brushing and social events

You can even track your progress in the Invisalign app.

How long does Invisalign take?

Most Invisalign cases take between 9–18 months, depending on the level of movement required. Minor cosmetic cases may finish faster, while more complex tooth movements may take slightly longer.

Who is this Treatment for?

Invisalign is suitable for adults, teens and professionals who want straighter teeth without visible braces. It can effectively correct:

  • Crowded or overlapping teeth

  • Gaps and spacing issues

  • Mild to moderate bite problems

  • Relapse after childhood braces

  • Misalignment affecting confidence or hygiene

Healthier Gums and Teeth

Straighter teeth aren’t just cosmetic. They are easier to clean and less likely to trap plaque. Invisalign aligners support long-term oral health by improving alignment while allowing you to brush and floss as normal.

✔ Easier hygiene compared to fixed braces
✔ No food restrictions or bracket damage
✔ Supports fresher breath and healthier gums
✔ Comfortable, smooth edges with no irritation
✔ Can be removed for special occasions

For more background, the Oral Health Foundation provides independent advice on clear aligners.

How much does Invisalign typically cost?

The cost of Invisalign in the UK typically ranges from £2,000 – £5,000, depending on the complexity of movement and the number of aligners required.

At Birchgrove Dental, Invisalign treatment starts from £3,950, with optional payment plans to spread the cost monthly.

Cost can vary based on:

  • Number of aligners required

  • Whether one or both arches are treated

  • Length of treatment

  • Optional extras such as whitening or retainers

A fixed quotation is provided before treatment begins – no hidden fees.

Who will treat me?

Invisalign at Birchgrove Dental is provided by Dr Craig Lewis, GDC 210741, the practice’s clinical director. Craig holds a Postgraduate Diploma in Orthodontics and has more than 11 years of experience treating adults and children orthodontically. He is trained and approved in Invisalign clear aligners, Damon braces, Ormco ceramic Symetri, Six Month Smiles, Quick Straight Teeth and the Inman Aligner, so an aligner is a recommendation rather than the only thing on offer.

Dr Marco Yang, GDC 210842, has also trained further in clear aligner and ceramic brace treatment and treats aligner cases at the practice.

Because we work with 6 different straightening systems, we will tell you at the assessment if a fixed brace would give you a better result than Invisalign for less money. That happens more often than the aligner marketing suggests.

Our clinicians are fully registered with the General Dental Council (GDC) and follow current orthodontic standards for safe aligner treatment.

What Patients Say About Us

I started my treatment with Craig about a year ago and I now have a full set of lovely straight teeth. Craig was brilliant throughout the whole treatment, and would always explain what he was doing and why and the next steps. Anabelle Harrington – Personal Assistant

I’ve recently had braces and was completely thrilled with the result. Craig is a really nice guy with obviously bags of knowledge and expertise, he’s extremely professional and I felt at ease before, during and after my treatment. I would highly recommend this cosmetic Dental practice and dentists Sophie Powell

Fantastic results in a short space of time! Wish I had the braces fitted years ago. Craig has been superb throughout the process, I can not praise Birchgrove Dental Practice enough! Christopher Hyde

Frequently Asked Questions

Invisalign invisible braces clear aligner close-up

They are virtually invisible rather than completely invisible. The aligners are clear, but small tooth-coloured attachments are bonded to some teeth to control movement, and these are visible at close range. Most people do not notice them in normal conversation.

Treatment at Birchgrove Dental starts from £4,950, including all aligners, review appointments, teeth whitening and retainers. You receive a fixed written quotation before treatment begins.

Expect mild tightness or soreness for a day or two after changing to a new aligner. This is the aligner working. Persistent or sharp pain is not normal, so contact us if it occurs.

No. Aligners must be removed for all food and for any drink other than water, and then your teeth must be brushed before the aligners go back in.

Treatment slows, or stalls, and teeth can drift out of step with the planned sequence. Aligners need 20 to 22 hours of wear daily to work as planned.

Yes, permanently. Teeth continue to move throughout life. Both a hidden wire retainer and night-time removable retainers are included in your treatment price.

Use a soft toothbrush and cool water, or Invisalign cleaning crystals. Avoid hot water as it can warp the trays.

Invisalign is not available through NHS orthodontics. The NHS typically provides fixed metal braces for eligible patients under 18. See the NHS guide to orthodontic treatment for more info.
