Why Invisalign®

Invisalign® treatment uses a series of clear plastic removable orthodontic aligners to gently move your teeth in small increments. For the best results, Invisalign® clear aligners are to be worn 20 to 22 hours a day. Each aligner is slightly different, you’ll wear a set of aligners for one to two weeks or as prescribed by your dentist, before moving onto the next set.

Advantages of Invisalign® are:

  • Nearly invisible
  • Removable
  • Less discomfort
  • Clearer timelines
  • Better oral health

Invisalign® uses advanced 3D software technology, that allows you to see the end results of your treatment before you even begin. An orthodontist or Invisalign® trained dentist will be able to advise whether Invisalign treatment is right for you. 

With Invisalign®, no one ever has to know!
