4 Tips To Reduce Invisalign Lisp
Considering Invisalign to straighten your smile but worried about speaking with a lisp? Don’t worry—it’s completely normal to experience a slight lisp when you first start wearing aligners. The good news is that it’s temporary, and with a little practice, you’ll be speaking normally in no time. Here are four tips to help you reduce the lisp and adjust to your new aligners more quickly.
Practice Speaking as Soon as You Get Your Aligners
The best way to overcome any lisp caused by Invisalign is to start talking as soon as you receive your aligners. The more you speak, the quicker your mouth will get used to the sensation of wearing them. Try reading aloud, talking with friends, or even singing in the shower. The more you practice, the faster your mouth will adapt, and the lisp will fade away.
Don’t be shy—give yourself time to adjust, and you’ll be surprised at how quickly your speech improves. Just like with any new habit, repetition is key.
Be Consistent and Keep Your Aligners In
It’s tempting to remove your Invisalign trays during important conversations, but keeping them in as much as possible will help your mouth adjust more quickly. Removing your aligners frequently makes it harder to get used to the feel of them in your mouth, which can prolong the lisp.
Consistency is important—not only for your speech but also for your overall Invisalign progress. The more you wear your aligners, the quicker you’ll see results and the sooner you’ll feel comfortable speaking with them.

Switch to New Aligners at Night
Each time you switch to a new set of Invisalign aligners, you may notice a slight increase in discomfort or lisping. A simple trick to minimize this is to switch to your new aligners at night. This way, your mouth has several hours to adjust while you sleep, and by the time you wake up, the initial adjustment period will have passed.
This tip helps ease the transition between sets and reduces any noticeable lisping during the day.
Stay Hydrated
Dry mouth can make your lips stick to the aligners, which can worsen the lisp. To avoid this, make sure to drink plenty of water throughout the day. Staying hydrated helps your mouth stay moist, which in turn makes it easier to speak clearly with your aligners in. This tip is especially important in hot weather, when dehydration is more common.
A well-hydrated mouth not only helps with speech but also keeps your aligners and mouth clean, contributing to better oral health during your Invisalign treatment.
