Do Braces or Aligners Affect How You Speak?

If you’re considering orthodontic treatment, you might be wondering whether braces or aligners will change the way you speak. It’s a fair question—and one we hear often at our Dee Why practice.

The short answer? Some people notice a mild, temporary change at first, but then speech settles back to normal pretty quickly.

Why Your Speech Might Change Initially

Braces and aligners slightly alter the “map” inside your mouth—where your tongue naturally rests, how air flows when you talk, and how your lips and cheeks move to form words. That’s most noticeable with sibilant sounds like “s,” “z,” “sh,” and “ch.” Your tongue is incredibly adaptable, though, and it doesn’t take long for it to adjust to the new landscape.

Think of it like breaking in a new pair of shoes. They might feel a bit unusual at first, but within days you forget they’re even there.

Common Myths About Orthodontics and Speech

“Braces permanently change your voice.” False. Your voice—its pitch and tone—doesn’t permanently change from orthodontic appliances. What you’re really hearing is a temporary adjustment in pronunciation, not a fundamental shift in your vocal quality.

“You won’t be understood.” Early lisps are typically mild and short-lived. Most people around you won’t even notice after the first few days. You might be hyper-aware of the change, but chances are your mates at the surf club or colleagues at work won’t pick up on it at all.

“Aligners never affect speech.” They can, briefly—usually very minor and gone within days. Because aligners add a thin layer over your teeth, your tongue needs a moment to recalibrate. But honestly? The adjustment period is often shorter than with traditional braces.
