Listerine Total Care Enamel Guard is formulated to defend tooth enamel against acid erosion and the plaque bacteria, which cause caries, in three distinctly different ways; its high fluoride content remineralises and hardens enamel, its essential oils are highly active against pathogens that attack enamel and as a mouthwash it can reach all enamel surfaces more easily than a toothpaste.
Several studies [1, 2, 3] have shown that an optimum short term salivary pH level, which can be achieved by use of Listerine Total Care Enamel Guard, maximises fluoride uptake and mineral exchange.
The pH level then returns rapidly to a level well above that for acid erosion to take place.
The mouthwash contains 225 ppm fluoride which has been proven to increase fluoride levels above those for brushing with a fluoridated toothpaste alone. [4,5]
In fact, although Enamel Guard contains half the fluoride level of Sensodyne ProNamel evidence6 shows that it provides the equivalent enamel strengthening benefit.
Further studies have shown that dental plaque may constitute a barrier to fluoride uptake [7 ,8] so managing the plaque biofilm is key to helping maximise fluoride uptake and reducing the risk of caries.
It’s important therefore to understand that Enamel Guard contains essential oils which have been proven to penetrate the biofilm effectively and help kill more plaque bacteria than any other daily use mouthwash.[9,10]
A six-month study by Sharma et al  showed that the adjunctive use of Listerine produces an incremental six-month plaque reduction of 51.9% when compared to brushing and flossing alone. Listerine also acts very quickly killing key acid-producing oral pathogens (S.mutans, P.intermedia, F.nucleatum) found in plaque biofilm in 30 seconds .
Unlike a fluoridated toothpaste, Listerine Total Care Enamel Guard’s hydrodynamic ability enables it to reach all five exposed tooth surfaces including inter-proximal regions.
With the potential to provide all round protection for enamel, Listerine Total Care Enamel Guard is a logical adjunct to the oral hygiene regimen offering protection against acid erosion and the plaque bacteria which cause caries.
