Invisalign Basics

What is Invisalign?

Invisalign is a convenient, hygenic and almost invisible orthodontic treatment that utilises clear, plastic aligners to realign and straighten teeth.

How does Invisalign work?

The Invisalign system works using a series of almost invisible aligners that are custom designed and fabricated by your Invisalign provider.

Sets of aligners are worn for a fortnight before you change over to a new set which shifts your teeth incrementally each time.

When you get to your last set of aligners according to your treatment plan, your teeth should all be in their final desired positions.

What types of Invisalign clear aligners are available?

  •  Invisalign First: Designed for kids aged 7-11 years to treat and improve a range of developing teeth straightening issues.
  • Invisalign Teen: For active, younger teens who still have erupting teeth and lower jaw advancement issues.
  • Invisalign Express (i7)/Invisalign Lite: For adults with minor teeth alignment issues. Ideal solution for minor front tooth corrections over a 3 to 7 month period.
  • Invisalign Full: A comprehensive 12 to 18 month treatment plan specifically designed for adults who require mild to moderate orthodontic ttreatment.

Minor pressure sensations commonly occur as your teeth readjust to the new set of aligners. These sensations should subside after a few days.

Can pregnant women receive Invisalign treatment?

Yes, pregnant women can receive Invisalign treatment because the aligners are 100% bio-safe and can be worn throughout pregnancy. The biggest issue with pregnant women undergoing teeth alignment treatment of any type are pregnancy hormones which may loosen their teeth due to ligament laxity.

Can I use chewing gum or smoke while wearing Invisalign clear aligners?

If you need to do either habit, remove your aligners first and replace as soon as possible. Any unnecessary time spent not wearing your aligners may impact on the success of your Invisalign treatment. Wearing your aligners for 20-22 hours a day minimum is a requirement.
