Invisalign
Invisalign is a brand of clear aligner orthodontics that straightens teeth using a series of custom-made, removable transparent trays instead of fixed braces. Each set of aligners moves the teeth slightly closer to their final position and is worn for around two weeks before the next. The aligners are nearly invisible and can be taken out to eat and clean.

Invisalign — frequently asked questions
What is Invisalign?
Invisalign is a brand of clear aligner orthodontics that straightens teeth using a series of custom-made, removable transparent trays instead of fixed braces. Each set of aligners moves the teeth slightly closer to their final position and is worn for around two weeks before the next. The aligners are nearly invisible and can be taken out to eat and clean.
How long does Invisalign treatment take?
Invisalign treatment usually takes around 6 to 18 months, though minor corrections can be quicker and complex cases longer. Aligners should be worn for 20 to 22 hours a day for treatment to stay on track. Your dentist or orthodontist will estimate the timeline after assessing your teeth.
Is Invisalign available on the NHS?
Invisalign and other clear aligners are not normally available on the NHS, which provides fixed braces for eligible under-18s with a clear clinical need. Adults and those choosing aligners for cosmetic reasons usually pay privately. A consultation will confirm whether you are suitable.
Does Invisalign hurt?
Invisalign is generally comfortable, but it is normal to feel mild pressure or tenderness for a day or two each time you start a new set of aligners, a sign the teeth are moving. The trays have smooth edges, so they tend to cause less irritation than fixed braces.
