Botox or aromatherapy? new study pits two treatments against sleep grinding
NCT ID NCT06674733
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study compared two treatments for sleep bruxism (teeth grinding): botox injections and marjoram oil aromatherapy. Thirty adults with sleep bruxism were split into two groups, receiving either botox or marjoram oil. Researchers measured changes in jaw muscle thickness, pain, and sleep quality over three months to see which approach worked better.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- botulinum toxin-A (Botox) and marjoram oil
- What this could lead to
- If successful, this could point toward a non-surgical treatment option for sleep bruxism, potentially easing jaw pain and improving sleep quality.
- What could go wrong
- This is a small, early study with only 30 participants, so results may not apply to everyone. Botox injections carry risks like muscle weakness, and marjoram oil's effectiveness is not well proven.
