My Doctor is Making Me Wait 3 Weeks Instead of 2 in Between New Trays.... Why is That?

I understand that you feel like your teeth move fast, most people feel the same.  Its not the movement that your orthodontist is concerned with.  Its the stabilization of that movement before moving them more.

Ask him why he wants you to change aligners every three weeks rather than two. I'm sure he can give you a reasonable explanation. 

I am sure he can show you the computer simulation of your teeth movement if you ask.  I don't normally show this to my patients unless asked.

Best,

Dr. Alper

Some times there might be a reason to wear the aligners more than two weeks:

1. The patient may not be wearing the aligners as instructed.

2. The aligners are not tracking as they should.

3. There is difficult movement.

All else being equal two weeks should be sufficient.

The Doctor can easily show you your tooth movement on his computer

While the teeth may seem to have moved within days of wearing a new aligner, complete movement often takes the entire 2 weeks (some have tried to move their case along and change aligners every 7 days.  Don't).  A 3 week course may mean that your teeth are not tracking as expected.

Express your concerns, I am sure that your doctor can explain it all and show you your case on the computer.
