I use the Regular Listerene mouthwash after being directed by my dentist.
It comes in a 250 ml bottle which costs around Rs.105
It has a really potent cleansing activity and my mouth feels fresh for a long period of time. It has a good bactericidal action and does not cause odour in my mouth.
Flavour is actually mint like and is really refreshing in the morning.
After using it twice daily over a period of 2 months my oral problems and gingivitis reduced drastically and I'm still using it.
On the whole Listerene mouth wash is not only a potent mouthwash but is also helpful in relieving gum problems and odour in breath.
