The million-dollar question you may be asking: do retainers straighten teeth like other orthodontics? The short answer is no. They don't apply the steady force over time needed to make major changes to your teeth' position. Instead, they simply hold your teeth in place.

Can you use retainers to straighten teeth?

Does wearing an old retainer to straighten teeth work? As it turns out, yes, it can. Retainers don't just keep your teeth in place, after all. Because they are custom made, they can also help improve any minor oral issues you might find years after having your braces removed.

Can retainers straighten teeth without braces?

Removable retainers:

Invisalign offers teeth straightening without braces by using a set of clear retainers instead. These retainers are almost invisible and can be removed for eating, drinking and socialising, making them popular with people in the spotlight.
