Chew your way to a new jawline? science puts hard gum to the test
NCT ID NCT07726511
First seen Jul 24, 2026 · Last updated Jul 24, 2026
Summary
This pilot study investigates whether regularly chewing a hard gum for four weeks can produce measurable changes in facial shape. Twenty healthy adults aged 20 to 40 will chew a standardized hard gum every other day, and researchers will use 3D facial imaging to track any shifts in soft-tissue contours. The goal is to see if a simple chewing exercise can alter facial morphology.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- hard gum chewing (Jawliner®)
- What this could lead to
- If chewing hard gum measurably alters facial soft tissues, it could point toward a simple, non-invasive way to influence facial appearance or muscle tone.
- What could go wrong
- This is a very small pilot study with only 20 participants, so results may not apply broadly. Chewing hard gum could also cause jaw soreness or temporomandibular joint discomfort.
