New mouthguard design put to the test in small study
NCT ID NCT04056559
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tested new adaptable mouthguards in 14 healthy adults aged 18 to 35. Researchers checked how the mouthguards affected breathing, comfort, and jaw muscle activity during exercise. The goal was to see if the prototypes work well, not to treat any disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Adaptable mouthguards (device)
- What this could lead to
- If successful, this could lead to better-designed mouthguards that are more comfortable and less disruptive to breathing during exercise.
- What could go wrong
- This is a very small, early-stage study with only 14 healthy young adults. Results may not apply to athletes or people with dental issues. The mouthguards are prototypes and may not perform as expected in real-world use.
