Good oral hygiene was important to us
The orthodontist recommended removable aligners, so we went with them because they seemed to be the most practical, clean and aesthetically pleasing option.
And I think it's easier for kids to take care of their teeth with aligners. Food is more likely to get stuck if they have fixed brackets and wires on their teeth. And aligners definitely look nicer.
But it was important to me that the aligners were just as effective as fixed braces, otherwise we wouldn’t have gone with them.
