Are you thinking about getting Invisalign? No doubt, you are looking forward to enjoying straighter teeth and discreet treatment. However, it is important to note that the clear aligners will completely cover your teeth. Naturally, you might wonder if that will affect the way you speak. This blog post explains some points that you should keep in mind as you embark on your orthodontic journey.

How Common Are Speech Changes with Invisalign?

Speech is the result of complex interactions between the teeth, tongue, and other important structures. Fortunately, Invisalign aligners fit closely over your teeth, so they should not have a huge impact on the mechanics of how you speak. A frequently cited study from Nedwed even reported that 93% of patients noticed no significant speech difference with Invisalign. Most people who do notice a change hear a slight difference at first, which then improves as the mouth adapts to the aligners.

What You May Notice When You Speak

The most common speech change with Invisalign is a mild lisp. Sounds such as “s” and “z” may seem softer or less precise during the first days of treatment. You may also notice that you speak a little more slowly as you learn where to place your tongue. These changes usually fade with time and practice.

How You Can Adjust Faster

If your speech sounds and feels different at first, a few simple habits may help you adapt more quickly:

  • Practice out loud. Read a page from a book, repeat difficult words, and talk throughout your day. This helps your tongue learn the new shape of your teeth.
  • Give yourself time. Some people adjust within days, while others need a few weeks. Consistent wear often helps you adapt sooner.
  • Call your dentist if the problem lasts. A tray that does not fit well may affect speech longer than expected. Dr. Thomas can identify the problem and help you find a solution.

Invisalign’s potential impact on your speech is just one factor to consider as you think about your orthodontic treatment options. Many people find that this is a minor issue that is easy to deal with!
