Bad breath will lead you to cavity in your teeth because the germs will grow and you will shame to talk closest with any one.
The best way is to use toothpaste like:-
1.Himalaya Dental Cream
As its a branded toothpaste which contain mixture of ayurvedics like kapur ,Neem,Lavang, Babool etc. This will realy help you to prevent your bad breath as well as other problems of your mouth too.
2.Dabur Meswak Tooth Paste
It is also an ayurvedic Tooth Paste too. It helps in reducing tooth decay , fight plaque, preven Gum disease and bad breath.
New pesodent toothpaste is best for you.
I must suggest you to use liquid cleaner for your total mouth at night before bed that will reduce the bad breath germs and in morning you will feel fresh after brushing anyone of the above toothpaste.
BEST OF LUCK FROM,
