Product Overview
Listerine Advanced Defence Gum Treatment Mouthwash 500ml offers targeted gum care with an invisible protective shield to help combat plaque bacteria, reduce signs of gingivitis and promote healthier gums.
Description
Listerine Advanced Defence Gum Treatment Mouthwash 500ml is a clinically proven therapeutic oral rinse designed to help treat gum disease (gingivitis) and support overall gum health. Its specialised formula creates an invisible protective shield that helps prevent plaque-causing bacteria from attaching to teeth and gums, allowing gums to begin to repair and return to a healthier state. When used as part of your daily oral care routine, this mouthwash can reduce signs of gum bleeding and inflammation, contributing to stronger, fresher-feeling gums.
This mouthwash is formulated with Ethyl Lauroyl Arginate (LAE), an antibacterial ingredient shown to help disrupt plaque and support gum healing.
