Speaking with Invisalign

When considering Invisalign for your orthodontic treatment, you might wonder what impact the aligners might have on your ability to speak. Here, our Delta dentists offer their top tips for getting used to speaking while wearing your Invisalign aligners.


Pretty much any dental or orthodontic appliance has the potential to affect your speech, especially those that add extra thickness to the roof of your mouth, or to back of your front teeth where Invisalign aligners sit.

Is Invisalign likely to cause speech impediments?

The great news is that Invisalign aligners are unlikely to cause speech impediments because the aligners are made from very thin plastic. This makes any impact they may have on your speech relatively minor.

It is, however, important to note that when you first have your Invisalign brace system placed for treatment, you may notice a slight lisp to your speech. The lisp will probably be most obvious when you make “s” or “sh” sounds.

This slight lisp will most likely only be noticeable to you, not to anyone else, and should fade as you get used wearing to your aligners.

Studies have shown that 93% of Invisalign patients reported no difficulties with speech while wearing their aligners. So, overall you probably don’t need to worry. 

What are some tips to reduce a speech impediment, if I have one, while wearing Invisalign?

If you do notice that your Invisalign aligners cause you to speak with a slight lisp or speech impediment, just remember: practice makes perfect.

One of the best ways to overcome any problems is by repeatedly practicing the pronunciation and enunciation of the words you are struggling with. This repeated practice will also help you to get used to your new dental appliance. Try reading out loud to yourself (or to others), chatting to your pets, or just having conversations with friends or family members that you trust.
