In this study, tooth bleaching was performed by using a helium‐based low temperature atmospheric‐pressure plasma jet (He‐APPJ) with saline solution to avoid ozone and hydrogen peroxide (H 2 O 2 ) harm. In this study, tooth samples were treated through three approaches, namely a helium flow with saline, H 2 O 2 gel, and He‐APPJ with saline. The bleaching efficacy of the He‐APPJ treatment was the highest among the three groups. Furthermore, scanning electron microscopy images showed that enamel treated with He‐APPJ was much less damaged than that treated with H 2 O 2 gel. In addition, ozone tests showed that APPJ produced little ozone (<0.35 ppm). In conclusion, He‐APPJ with saline solution achieves higher bleaching efficacy and is less harmful than methods that use H 2 O 2 gel.
