At a glance
Summary
This mouthwash contains beneficial ingredients like xylitol, which helps reduce cavity-causing bacteria, and sodium bicarbonate, which acts as a gentle abrasive. However, it also includes sucralose and PEG-40 hydrogenated castor oil, which are less desirable due to potential health concerns. The absence of alcohol is a positive aspect, but the presence of multiple additives slightly lowers its overall rating.
