Can Orthodontics Improve Speech Impediments?

September 7, 2023

Orthodontic treatment involves straightening teeth and correcting jaw alignment for a beautiful, functional, pain-free smile.

However, did you know orthodontics can play a role in improving speech difficulties related to teeth and jaw alignment issues?

Here’s how orthodontic treatment may help speech impediments and what you can expect from your treatment.

Lisps and Creating Specific Sounds

Certain speech impediments, such as lisps or difficulties pronouncing specific sounds, can be caused by misalignment of the teeth and jaws. To correctly pronounce words, the tongue needs to press against the teeth in a certain way, but when teeth are missing, crooked, or crowded, it can impact how the sound comes out.

In such cases, orthodontic treatment, whether through traditional metal braces or clear aligners, can improve speech by aligning the teeth and jaws into their proper positions. In children, Phase I orthodontic treatment combined with speech therapy can help correct speech impediments related to malocclusion, or an improper bite [1].

When the teeth are properly aligned, it can positively impact the positioning of the tongue and lips, allowing for better articulation and pronunciation of sounds. This, in turn, can lead to clearer speech and improved confidence when speaking.

Not All Speech Impediments Are Caused By Dental Issues

It’s important to note that not all speech impediments are solely caused by orthodontic issues.

Some speech difficulties may be due to physiological factors, such as developmental or genetic disorders, as well as hearing loss [2]. In such cases, orthodontic treatment alone might not fully address the underlying cause of the speech impediment.

Collaborative treatment with speech therapy or other interventions may be necessary for comprehensive improvement. Talk with your orthodontist if you are concerned about a speech impediment and wondering if braces or clear aligners will improve it.

Seeking the Right Care for You or Your Child

If you or your child is experiencing speech difficulties, it’s important to consult both an orthodontist and a speech-language pathologist (speech therapist) to determine the specific nature and cause of the speech impediment, as orthodontics alone may not correct the issue [3]. Your orthodontist and speech therapist can work together to develop a comprehensive treatment plan that addresses any orthodontic issues as well as speech impediments not directly related to malocclusion to achieve the best outcome.

Schedule a Consultation With Your Orthodontist

So while orthodontic treatment can improve speech impediments related to dental and jaw misalignments, it may not completely resolve all speech difficulties.

If you’re concerned about a speech impediment, schedule an appointment with your orthodontist today to find out if your teeth or bite could be at the root of the problem. Collaboration between orthodontists and speech-language pathologists can lead to a holistic approach to treating speech impediments, ensuring comprehensive care and improved speech outcomes.
