Continue to free assessmentAm I suitable for clear aligners?
Aligners work well for many cases of crowding, gaps and crooked teeth. Start your free assessment and a dentist will tell you if they suit you.
How long does treatment take?
It depends on your teeth. Many treatments take around [X-Y] months. You will know your timeline before you start.
Do aligners hurt?
You may feel some pressure for a day or two with each new stage. This is normal and means they are working.
Can I eat and drink with them in?
Take them out to eat and to drink anything other than water, then brush before putting them back in.
Is teeth whitening safe?
Yes, when prescribed by a registered dentist. In the UK, whitening must be carried out or prescribed by a dental professional, and we check your suitability first.
Can I whiten my teeth during aligner treatment?
Many people whiten at the end of treatment. Your dentist will advise the best time for you.
What happens after treatment?
You wear retainers to keep your teeth in their new position. Retainers are included with aligner plans.
