Teeth straightening FAQs
Common questions from our Tonbridge patients — ask us anything else at your consultation.
How much does teeth straightening cost?
Our clear aligner treatment is £3,250 to straighten one arch (your upper or lower teeth) or £4,250 for both arches. That’s an all-inclusive price covering your aligners, a specialist orthodontist-approved plan, professional teeth whitening, and both fixed and removable retainers — with finance available to spread the cost.
What’s the difference between Invisalign and 32Co?
Both use clear, removable aligners to gently straighten your teeth. Invisalign is the best-known aligner brand worldwide. With 32Co, every treatment plan is designed and approved by a specialist orthodontist — giving you specialist-grade oversight, high precision and the ability to treat more complex cases. At your consultation we’ll recommend the best option for your smile.
How long does treatment take?
It depends on how much your teeth need to move. Many people finish in around 6 to 12 months, while simpler cases can be quicker and more complex ones take a little longer. We’ll give you a clear timeframe after your scan and plan.
Are clear aligners really invisible?
They’re very discreet. The aligners are made from clear, smooth plastic that fits closely over your teeth, so most people won’t notice you’re wearing them — and you can take them out for photos or special occasions.
Is it painful?
No — clear aligners are gentle. You may feel mild pressure for a day or two each time you move to a new set, which is a sign your teeth are moving. There are no metal wires or brackets to rub or irritate your mouth.
Can I have treatment if I wore braces as a teenager?
Absolutely. Teeth often shift again years after braces (called relapse), and clear aligners are a popular, discreet way to straighten them back. It’s one of the most common reasons adults come to see us.
