Speaking with Invisalign

Like with any orthodontic treatment, there is an adjustment period with Invisalign during which patients will encounter certain difficulties as they become used to wearing their aligners. Here, our Ontario dentists provide some pointers on how to get acclimated to speaking with Invisalign Clear Aligners.

Almost any dental or orthodontic device has the potential to have an impact on your ability to communicate verbally. Orthodontic appliances that add extra thickness to the roof of your mouth or the backs of your front teeth are likely to create mild speech difficulties, and Invisalign aligners are a good example of such appliances.

Is Invisalign going to cause difficulty speaking?

Invisalign aligners are composed of thin, transparent plastic, which means that any influence they may have on your speech should be fairly minimal. However, some people may experience some difficulty speaking.

When your Invisalign aligners are first put on for treatment, you may notice a minor lisp in your speech, particularly when you produce "s" or "sh" sounds. This is normal during the treatment process.

Fortunately, this little lisp will most likely only be apparent to you, and not to anybody else with whom you are conversing, and it should progressively decrease as you become more accustomed to wearing aligners.

Are there ways to help reduce difficulty speaking?

If your Invisalign Clear Aligners are causing you trouble speaking, try following some of these tips:


Practice speaking with proper pronunciation in a private setting. Make an effort to over-enunciate and concentrate on the letters that are the most challenging for you, such as S's, T's, D's, and C's.

Read Aloud

Try reading aloud to yourself or to a loved one to see if it helps. Passages that you find particularly difficult should be repeated.

Record Yourself

Recording your practice sessions with a portable recorder or your phone is a good idea. This will help you to identify the sounds, words, and phrases that you are having the greatest trouble speaking.

Speak Slowly

Spend time thinking about what you're going to say and speak at a calm, relaxed pace.

Stand Up Straight

Proper airflow through the larynx (voice box) is made possible by good posture, which makes speaking easier.


The above suggestions can help you go back to your typical speaking ability in no time.

If your Invisalign aligners cause you to speak with a little lisp or speech impairment, try to remember that practice makes perfect. Or at least, practice makes better.

The quickest and most straightforward method of overcoming any difficulties is to continually practice the pronunciation and enunciation of the words with which you are having difficulty. Practicing challenging words will assist you in becoming used to your new clear aligners. You may also read aloud to yourself (or to others) while wearing your aligners or enjoy having discussions with family and friends that you can trust to help you become used to wearing them.

If you're worried you might have trouble speaking with your Invisalign Clear Aligners, contact our Ontario dentists to discuss your concerns.
