Orthodontics & Speech: How Braces, Expanders & Aligners Affect Talking

Many patients—especially kids, teens and professionals—wonder:

• “Will braces make me talk funny?”
• “Will a palate expander make it hard to say certain words?”
• “Will Invisalign affect my speech in meetings or at school?”

At Othman Orthodontics in Lombard and Orland Park, IL, we talk about speech at nearly every consultation. The good news: most speech changes are temporary and improve with practice and time.

In this guide, we’ll explain:

• How different appliances (braces, expanders, aligners, lingual braces) can affect speech
• How long speech changes usually last
• Tips to adapt more quickly

Braces & Speech

Traditional braces—whether metal braces with colors or clear braces—are attached to the front surfaces of your teeth.

Will Braces Change My Speech?

Most patients notice little to no lasting change in speech from regular braces. You might experience:

• Very slight differences in the first few days as your lips and cheeks adjust.
• Mild difficulty pronouncing some sounds if braces create extra bulk or initial soreness.

For the majority of patients, speech returns to normal quickly—often within days—once your mouth adjusts to the new hardware.

Palatal Expanders & Speech

Palatal expanders sit on the roof of the mouth (palate). Because of their position, they can affect how the tongue moves and touches the palate to form certain sounds.

Common Speech Changes With Expanders

Especially in the first week or two, kids and teens may notice:

• Changes in “s,” “sh,” “ch” and “j” sounds.
• Slight lisping or “thicker” sounding speech.
• More saliva or extra swallowing as they adapt.

This is normal and usually improves as your child’s tongue learns how to work around the expander.

Helping Kids Adapt

• Encourage reading aloud for 5–10 minutes a day.
• Practice tricky words or sentences together.
• Reassure your child that this is temporary and part of the process.

Invisalign & Speech

Invisalign and Invisalign Teen use clear aligners that fit closely over teeth.

Will Invisalign Make Me Lisp?

Some patients notice:

• Slight lisping or change in “s” sounds when wearing the first set of aligners.
• Speech feels different for the first day or two of each new tray.

In most cases, this is mild and temporary. As you wear your aligners consistently, your tongue quickly adapts and speech sounds normal again.

Tips for Adapting to Invisalign

• Wear aligners as directed—taking them out more can slow adaptation.
• Practice speaking, reading and even singing with aligners in.
• Give yourself a day or two of “practice” time before important presentations if you’re starting a new set.

Lingual & Incognito™ Braces & Speech

Lingual braces and Incognito™ braces sit behind the teeth, closer to the tongue.

Speech Changes With Lingual Braces

Because the braces share space with the tongue, it’s common to experience:

• More noticeable speech changes at first than with regular braces.
• Difficulty with “s,” “t,” “d” and “l” sounds initially.
• Some tongue soreness as it adapts to the new surfaces.

With practice and time, most patients see significant improvement and often return to nearly normal speech.

Adapting Faster With Lingual Braces

• Read aloud daily—this trains your tongue and brain to adjust.
• Speak slowly and clearly when possible at first.
• Use orthodontic wax to smooth out any rough spots that bother the tongue.

Will Orthodontics Fix Speech Problems?

Orthodontic treatment is not primarily a speech therapy, but in some cases:

• Correcting open bites or severe overjets can improve certain sound productions.
• Aligning teeth can help the tongue find more natural positions.

If there are significant speech concerns, we may recommend working with a speech-language pathologist in addition to orthodontic care. Together, we can coordinate treatment to support both function and esthetics.

How Long Do Speech Changes Last?

While it varies from person to person, a general pattern is:

• Braces: minimal to mild changes for a few days, then normal speech.
• Expanders: a more noticeable adjustment period, often 1–2 weeks, with steady improvement.
• Invisalign: mild lisp for some patients for a few days with each new set, improving quickly.
• Lingual/Incognito: more significant initial changes, improving over weeks with practice.

The key is consistent wear (for aligners), patience, and practice speaking.

Tips for Parents & Adults Worried About Speech

• Plan big changes (like getting an expander or lingual braces) at times without major performances or presentations, if possible.
• Practice reading aloud daily to speed up adaptation.
• Communicate with teachers or employers if you expect a temporary adjustment period.
