What are ‘invisible braces’?
They are tough, clear plastic ‘aligners’ (moulds) that are used to straighten teeth. Several sets of specially moulded, slightly different aligners are made for each patient. Each set is worn for two weeks before being replaced with the next one. They are made from clear plastic, so they are nearly invisible. This means that no one need know you are straightening your teeth.
The aligners should be worn for 22 to 23 hours a day for the best results. They can be easily removed for eating, drinking, brushing, and for cleaning in between your teeth. You need to have all your adult teeth before you can have this treatment.
