How to straighten crowded or crooked teeth

If you landed here because you searched “how to straighten teeth without braces” (or anything along those lines), you’ve come to the right place! SmileDirectClub uses clear aligners to give you a straighter smile without wires and brackets, and we’ll explain exactly how that works. We’re not talking how the SmileDirectClub process works, but how our aligners straighten crowded or crooked teeth.

How SmileDirectClub aligners actually straighten teeth

SmileDirectClub aligners progress over a matter of months. Each month, you will have a series of aligners that go from soft to medium and then to firm, applying appropriate and even pressure throughout your journey to gently and safely move your teeth.

A new smile in as little as 4–6 months

You change your aligners from one set to the next as outlined in the individualized treatment plan created from your impression kit or 3D image made at the start of your Smile JourneyTM.

When you receive your aligners, the bags are clearly labeled so you know which aligner to switch to next. We also text you a reminder to switch your aligners so you don’t get off track.

Stay on track and you’ll have a new smile in as little as 4–6 months.1

When you’re done, you’ll need retainers to help keep your teeth in position. They’re also necessary to maintain your Lifetime Smile GuaranteeTM, which will protect your smile for life.2

And just like that, you’ll join the more than 1.5 million Club members who’ve straightened their teeth with SmileDirectClub.
