What's exactly the difference between the two? :confused:

Aligners put teeth into place (like braces), retainers hold their position after they've been moved orthodontically.

Well, I've had braces in my teens and still have the retainers which I used afterwards for a few months but my cousin just had Invisalign and they looked practically the same.:confused: She's now gutted to have spent nearly £5000 to have it done here in the UK.

They look the same but have different purposes.

Thanks for clarifying flossie.:)

Not a problem.:p Have a good night.

With invisalign you have different trays every 2 weeks to make your teeth straight but they take years to do.

With retainers they are just a mould of your straight teeth to hold them in position and you wear them at night.
