Spark Aligners

Advanced clear aligner technology

Spark aligners from £1,625

Terms and conditions apply.

If your confidence is affected by crooked or misaligned teeth, we can help. With clinical experience from trusted doctors around the world, Spark has created an advanced clear aligner system that is designed to meet the needs of the orthodontist and deliver your treatment vision.

When you choose to use Spark clear aligners for straightening your teeth, you will be provided with a set of 7 or more aligners (depending on the level of your treatment) that you change over week on week so that your teeth are re-aligned. You will see your Portman Smile Clinic orthodontist every 6 weeks or so to allow them to check up on how your treatment is progressing. Unlike fixed wire braces, aligners can be removed for eating, drinking or any special events where you might not want to wear them (but we would always advise wearing them as much as possible).

How does this treatment work?

How it works

Orthodontic treatment can be carried out at any age. Traditionally orthodontics are carried out when all of the adult teeth have grown, however early interceptive treatment can sometimes begin at a much younger age to help make treatment times shorter.

How we help

Our Portman Smile Clinic dentists and orthodontists are experts in the field of clear aligners, and happy to treat even the most complex of cases. With us, you are in safe hands.

How much it costs

Spark Aligners can start from £1,625. We have a full pricing table on this page.
