Everything You Want to Know

How long does treatment take?

Most treatments last between 6 to 18 months, depending on your case.

Is Invisalign painful?

You may feel slight pressure when starting a new set of aligners, but it’s generally very comfortable.

How often do I wear the trays?

For best results, wear them 20–22 hours per day—removing only to eat, drink, and clean.

Can I eat and drink with them on?

Only water is safe with aligners on. Remove them before eating or drinking anything else to prevent damage or staining.

How do I clean Invisalign aligners?

Use a soft toothbrush and clear liquid soap or special cleaning crystals. Rinse thoroughly and avoid using toothpaste, which can be abrasive.
