What Is Invisalign®?

Invisalign® is a clear brace system which uses a sequence of computer-designed aligners made from durable BPA-free plastic to gradually move your teeth by applying pressure in precision locations.


How Does Invisalign® Work?

Detailed impressions of your mouth are taken which are then scanned into a 3D modelling software.

Using specific parameters for tooth movement and detailed experience gathered from over 5 million cases, a unique set of movements are planned to straighten your teeth.



These movements are then broken down into stages and 3D printing is used to create individual aligners to carry out the planned tooth movement.

Once these aligners have been created you will visit your Invisalign® Dentist to have the aligners fitted and your progress will be reviewed periodically.

  • How Long Does It Take For Invisalign® To Straighten Teeth?

    On average, it takes between 20 to 30 aligners to straighten your teeth. These are changed approximately every 2 weeks. This gives an average treatment time of between 9 to 12 months. Each case is individual and to get a more accurate idea, we would advise you to contact us for a consultation.

  • Does Invisalign® Hurt?

    When first starting any orthodontic treatment there will be minor discomfort due to the pressure applied to move your teeth. You may find eating at first slightly slower due to the slight discomfort. This usually lasts only a few days after fitting your new aligners. Over-the-counter pain medication such as paracetamol or ibuprofen will provide relief against this discomfort.

Invisalign® vs Fixed Braces

There are certain advantages with each brace system. It is important to understand these before embarking on treatment.

In this section we will discuss Invisalign® vs other braces and the advantages and disadvantages of Invisalign® (clear braces) and more traditional fixed braces.

  •  Invisalign® (Clear Aligners)

    Advantages of Clear Aligners (Invisalign®)

    • They are more attractive than metal braces and are almost invisible.
    • More comfortable than fixed braces as they are smoother and less likely to catch your cheeks and tongue.
    • Can be removed to clean your teeth more easily than with fixed braces.
    • Tooth movements modelled in 3D so you can see the approximate anticipated result.
    • Can feel more gentle than fixed braces as the movements are smaller and more frequent.

    Disadvantages of Clear Aligners:

    • Patients need to be motivated to keep aligners in place for 22 hours per day.
    • Aligners need to be removed for eating and teeth must be brushed before putting them back in, this makes snacking difficult.
    • Clear aligners are not suitable for patients who require more extensive, severe tooth movement.
    • Attachments (made from small amounts of white filling material) are sometimes required to be placed on the teeth for the duration of the treatment. These attachments make the braces slightly more visible. The attachments are always removed by the end of treatment.
  • Fixed Braces

    These systems utilise brackets which are bonded to the teeth for the duration of treatment. Onto these brackets, titanium or stainless steel wires are tied in place using small elastic bands.

    Advantages of Fixed Braces:

    • Fixed in place which means you can eat with them in place and don’t have to worry about taking them in and out
    • Can be used in more complex cases when difficult tooth movement is required
    • Can be a little quicker than clear aligners
    • Can be cheaper than clear aligners

    Disadvantages of Fixed Braces:

    • Patients don’t often like the appearance of fixed braces.
    • Fixed in place, so more difficult to clean around and food can trap around them while eating
    • Wires can sometimes be uncomfortable at first and can cause small amounts of ulceration
    • Can be more uncomfortable than clear braces.

Who is Invisalign® Suitable For?

It is difficult to answer this question without having a consultation. Please contact us for an assessment.

Invisalign® can treat a number of different types of mild to moderate discrepancies. Discrepancies in tooth movements are called malocclusions. These malocclusions include:

Who is Invisalign® Not Suitable For?

Again, it is difficult to answer this question without having a consultation. Broadly speaking, treatment is only suitable for people when they only require mild or moderate corrections to their teeth.

There is a smile assessment tool which may be useful in determining if you are suitable. Please contact us for an assessment at the practice.

The Invisalign® Process Explained

1. The Consultation and Treatment Plan

First you will have an assessment of your teeth by a dentist. This includes a checkup if you aren’t a patient at our practice. Your needs and what you would like to change with regard to your teeth are discussed. Following this, if you are suitable and decide to go ahead with treatment impressions are taken of your teeth and sent to the laboratory.

After the impressions of your teeth and have been scanned a treatment plan will be formed. This is referred to as a ClinCheck®.



Your dentist will work closely with Invisalign® to optimise your treatment plan. When this is ready the number of aligners and stages will be identified. You will receive a ClinCheck® showing the anticipated movements of your teeth.

2. Delivering and Fitting Your Aligners

Once we have received your aligners, we will make arrangements to fit them. Sometimes you will be given a number of aligners and instructed on when to change them. Each one is numbered on the pouches they are delivered in and also printed on the aligner itself. Your progress will be reviewed with your provider roughly every 2-6 weeks.

At these appointments, your progress will be reviewed alongside the ClinCheck®. Sometimes small tooth adjustment is required to create space. This is the process where up to 0.5mm of enamel can be removed from each surface of the tooth, this allows further space for your teeth to be aligned. This is known as interproximal reduction.

This interproximal reduction is done with thin abrasive strips most commonly. This process is painless and doesn’t require any local anaesthetic. Here is the British Orthodontic Society information leaflet on interproximal reduction.

3. Refinements

Sometimes as you reach the end of your treatment, extra refinements may be required to give you the very best results. Often this is included in your treatment plan and requires a new set of impressions, from which a small set of aligners are made to move your teeth into their final positions. Once all tooth movements are completed the most important stage comes next

4. Results and Retention

Once you have reached the end of your treatment, it is really important to plan how we are going to hold the teeth in their new position. Usually teeth want to move back to their original position.


Hold the teeth in place so your teeth do not move back to their original position (also known as relapse). You will require life-long retainer use to ensure you keep your teeth in their new positions.

Fixed vs Removable Retainers:

Retention can either be removable, fixed or commonly – both may be required. Your Invisalign® Provider will discuss which options will be used and which would be the best on a case by case basis.

Invisalign® have their own system of retainers, Vivera Retainers® to hold teeth in their new position. These can be added to your treatment plan from the outset.

5. Follow-up Care

You will be advised by your Invisalign® provider how often you should be seen for a review and check-up following your treatment.

    Had a root canal treatment from Dr Skidmore and it was very quick and painless.

Frequently Asked Questions

  • What Do I Need to Bring to My First Appointment?

    Please Bring the Following Items With You to Your Appointment:

    • Completed written medical history, details and names of any medication
    • Funds adequate to cover appropriate fees.
    • If applicable, proof of any exemptions from NHS dental charges. If not exempt from NHS charges,
    • Proof of address (utility bill, driving licence)

    Please Bring the Following Items With You to Your Appointment:

    • Any updated medical history details and names of any medication changes
    • Funds adequate to cover appropriate fees
  • My teeth feel fine why do I need regular checks?

    It is great that your teeth feel fine, but we would recommend you have a dental checkup if you haven’t had one for a while. The reason for this is that often when dental symptoms appear the problem causing them is much more difficult to fix, and often with a worse prognosis. For example, early tooth decay often causes little or no discomfort or sensitivity. If this decay progresses then tooth loss or root canal treatment may be inevitable. With regular dental checkups the aim is to identify any problems early so they can be resolved with the best prognosis.

    We follow the guidelines set out by NICE with regard to dental examinations. Your risk to certain dental diseases will be assessed and a recall interval will be recommended from 3 to 24 months for your next check up.
