Briefly described: the stuff is very friendly, ensures long-lasting freshness and a balanced oral flora. Can also be used in verletztem- or sensitive gums - in this case, I find it even more effective than the "hard" Klopper as chlorhexidine etc., the only "chafe" the oral cavity but this unfold no long-term effect. Why is 'Meridol' So only the second best? Because 'Meridol Halitois' is well tolerated and effective, but milder (after) taste, and therefore more pleasant on the tongue.
