Invisalign is an orthodontic system that uses clear plastic aligners which gently move teeth into predetermined positions. The aligners fit very tightly over the teeth and are virtually invisible. Each set of aligners is worn for two weeks before it is exchanged for a fresh set that will progressively move the teeth.
Treatment continues until the teeth are straightened and can take anywhere from a few months to 18 months or more. Most people will need to wear their Invisalign aligners for at least a year.
Invisalign is suitable for many adults and for some older teenagers who are prepared to wear the aligners regularly, as compliance is very important to success.
Invisalign does produce a system specifically for teenagers and there are several other systems that can be used, some of which will only take a few months to correct minor or more cosmetic orthodontic problems.
