Is it OK for the Invisalign tray not to fit the first time?

“Is it OK for the Invisalign tray not to fit the first time?”

When you start comprehensive orthodontic therapy and decide on Invisalign over traditional braces, you will certainly have a variety of questions about wearing the clear aligners. At Moshiri Orthodontics, our patients who are starting their Invisalign treatment will be provided with instructions on how to wear, clean and take care of their trays. They also receive an handout reviewing all the instructions given at their appointment.

One of the questions that is often asked is it OK for the Invisalign tray not to fit the first time? Dr. Maz Moshiri has explains. “Invisalign is made of a series of trays that go on your teeth. They are made of plastic and are created by using your initial moulds and a 3D computer system to create all the steps till your teeth will be perfectly aligned.

Since there is some time between the moulds and the moment you get your Invisalign trays, it is possible for the trays to be a bit “tight”. I think this would best describe the feeling you have when putting the first aligner on or when changing with the next set. They are “tight”.

The entire system relies on the fact your teeth need to move to a desired direction. In order to achieve this, each aligner should push or rotate the tooth and it needs to not be a perfect fit for the current situation, but to force the tooth some more.

After wearing your trays for some time, you’ll notice the current set fits nicely. At the end of the first set you’ll be able to take out the trays very fast. The next set will be a bit tricky to put and after few days it’s getting easier again. By doing this, each set gets your teeth moving to the desired situation.

So, getting back to the question at hand. It’s normal for the first aligner to not fit perfectly or appear to not be able to be put on your teeth. No matter what might arise, we are here to help you with the first set and we can solve any issues that might arise,” say Dr. Maz Moshiri, a St. Louis orthodontist who provides beautiful smiles in the St. Louis and St. Charles area.
