Listerine Stay White 500ml Pack

What is it
64% of adults in the UK are concerned about teeth discolouration. Listerine Stay White is specially formulated with zinc chloride to prevent tartar build up to fight staining. Used twice daily, Listerine Stay White is proven to:
Kills up to 97% of germs left behind after brushing
Reduces plaque by up to 56% more than brushing alone
Provides up to 24 hours of fresh breath protection
Kills germs above and below the gum line to keep gums healthy
Helps prevent tartar build up to help keep teeth naturally white
Staining and discolouration are slightly different. Discolouration is caused by a filling bleeding within the tooth, causing it to change colour; or by the nerve dying inside the tooth and bleeding into the root canal. Discolouration can also be the result of erosion and wear of the tooth.
Directions
Especially effective when used morning and evening after brushing.
Pour 20ml (4 x 5 ml teaspoonfuls) into a glass, rinse around teeth and gums for 30 seconds, then spit out.
