Invisalign is becoming a popular treatment because it’s more discreet and comfortable than traditional braces. They are removable, so you can continue enjoying your regular diet without any worries! However, there is one thing that many people don’t expect, which is how their speech will initially change. It’s nothing major, but here’s what you should know and how you can get back to talking confidently again.

How Will Invisalign Change How I Speak?

In order for Invisalign to work effectively, you will need to wear thin, plastic trays for 20 to 22 hours every day. They apply pressure on your smile, shifting it into a healthier alignment. Regardless of how small they are, they do take up just a bit of room in your mouth. Your tongue may not be used to this, so you might feel like you’re bumping into them.

When this happens, you might develop a slight lisp. “S” and “z” sounds often come out as “th.” While this can be embarrassing at first, remember that it’s only temporary. It will take time for you to get used to your aligners, but it should happen the more you wear them. Generally, you can expect it to take a couple of weeks, but be patient with yourself.

What Should I Do to Get Used to My Invisalign Quicker?

Although your speech will have a minor and temporary change, there are some tips you can follow to get adjusted to your Invisalign sooner. Here are some simple ones that can help bring back your confidence when talking:

In the end, just be sure to give yourself some grace. Getting used to Invisalign will take time, so be sure to give yourself plenty of it. Eventually, you will develop your own routine that works for you. That way, you can start enjoying your journey to a straight smile you love.
