How Quickly Do Patients Usually Begin Seeing Results with Invisalign Express?

 Invisalign takes a modern approach to straightening teeth, using a custom-made series of aligners created for you and only . With any Invisalign category the teeth move gradually and gently to the movement desired. Whithin a week you can see minor changes every time you ghange to the next aligner.Choosing to straighten your teeth is a big decision that affects not only your appearance, but your lifestyle as well.

Invisalign is slower then conventional braces.  However that is not necessarily a negative, because with slower movement you have a lot less unwanted tooth movement.  However, with that said you should see some movement after about 10-12 weeks.

Each aligners only moves the teeth a very small amount. Actually seeing results may vary from patient to patient but some see result happen after only a couple of trays while others need to be shown the before picture to see results .

Your teeth will start moving instantly, and you'll know it since they will also be a little sensitive. However, I do agree that it generally will take a couple of trays to start noticing results.

Since the movement is so small with each aligner (usually 0.2 mm) it may be hard to percieve movement.  Many people report noticing movement at the 3rd or 4th aligner, but "mileage can vary".
