My best friend has a probem because sometimes he has a bad breath. He told me that he’s doing everything to prevent it. He brushed his teeth 2 times a day and using mouth wash 5 times a day. He always bring altoids peppermint and keep on eating more than 10 altoids in one day(not a box,10 circles). But still he has bad breath. Will his girlfriend have bad breath too if they keep on kissing each other? What should he do to avoid bad breath?

Try SmartMouth. It can be purchased at drugstores. Works 24 hours
Wow! if brushing your teeth and eating peppermints won’t help I’ll suggest change his eating habit. He probably has halitosis
there can be buildup of bacteria on your tongue that can cause odor
try using a tongue scraper
if that doesnt work see a doctor/dentist
I’d go and see a Dr if I were him. The bad breath may be a symptom of some bodily disorder – something wrong in his throat or stomach.
try to rinse your mouth using peppermint tea. and be sure to drink lots of liquids, as a dry mouth intensifies bad breath.
To get rid of chronic bad breath, he has to have his teeth cleaned professionally every 6 months. It doesn’t cost that much. He also has to floss every day. Try using an electric toothbrush. It will dislodge the old food that gets trapped under the gum line. It gets stuck in there, it rots and it smells.
Finally, he has to brush his tongue. This is where most of the germs that cause bad breath hide.
