Ozone gas may ease pain after wisdom tooth surgery
NCT ID NCT06802354
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed Phase 3 trial tested whether applying gaseous ozone to the extraction site after impacted wisdom tooth surgery can reduce common complications like pain, swelling, and difficulty opening the mouth. Twenty adults with similar wisdom tooth impactions received either ozone or a sham treatment for 30 seconds. Researchers measured pain, swelling, and healing over a week, and also tracked quality of life. The goal is to see if ozone can make recovery smoother.

- What this could lead to
- If it works, this could offer a simple, low-cost way to reduce pain and swelling after wisdom tooth surgery.
