The length of your treatment will depend on your specific needs and will be determined by your Invisalign-trained dentist. The average treatment for an adult is about 12 to 18 months and for teenagers, treatment length may vary depending on each individual case and will need to be determined by the dentist.

You should wear each aligner for 20 to 22 hours a day during your treatment for best results and a timely outcome.

You will visit your Invisalign-trained dentist for a check-up approximately every 6-8 weeks to see how your treatment is progressing. During your check-ups, your Invisalign-trained dentist will check that the aligners are fitting well and make any adjustments if necessary.

You'll be provided with enough aligners to last between visits to your dentist (usually 3-4 sets at a time). Your dentist will review your progress every 6-8 weeks and new aligners will be given to you at these appointments. It's best to speak to your dentist about how many aligners you will be provided with between visits.

In most cases, one aligner case is included in your patient starter kit.

You will usually change your aligners every 2 weeks. However, please follow your Invisalign-trained dentist's specific instructions regarding when you need to change your aligners as this may vary between patients.

Results with the Invisalign System usually start showing a few months after starting treatment.
