How Long Do I Need to Wear a Retainer After Invisalign Treatment?

Anna, you are asking a great question. Assuming you are beyond growth years (usually older then 18 years old) I'd like to encourage you to wear retainers 24/7 first 6 month after Invisalign finished active (moving teeth) stage. You invested your money and time to get straight teeth and a great smile. Let's keep them for life. I want you to be prepared to wear retainers at night  for the rest of your life. With your dental health in mind.

Teeth have the possibility of changing position throughout life. This is true whether or not there has been orthodontic treatment. So, for the best insurance that your new, beautiful smile will last for a lifetime, continue to use your retainer during sleeping hours - at least several nights a week.

I want my patients to wear there retainers for life. Wear them full time after treatment for at least 3 months and then nights only. If you detect tooth movement when they are out then go back to full time.
