Summary

This study tested whether a low-level laser applied after removing baby teeth could help children ages 5-8 feel less pain and heal faster. Each child had two teeth pulled: one side got the laser, the other got a sham treatment. Pain and wound healing were checked on days 3 and 7. The goal is to find a non-drug option for managing dental pain in kids.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
low-level laser therapy (LLLT)
What this could lead to
If it works, this could offer a simple, drug-free way to reduce pain and speed healing after tooth extraction in children.
What could go wrong
This is a very small, completed trial with only 18 children. Results may not apply to all kids or other types of dental procedures.
