I have been flossing since a young age and have only one filling for vegetarians is not so important but meat eaters definitely should,you can not always tell you have bad breath and people may not want to tell you. here is what to do,floss between every tooth especially the back ones if floss string smells rotten so will your breath.
Flossings a waste of time, just brush your teeth twice a day and chew some mint flavored chewing gum throught the day and you'll be fine
You can have your teeth cleaned by a qualified dentist once in six months or at least once a year. That will take care of your oral hygiene provided you brush your teeth properly twice a day.
No, this is horrible advice and absolutely no one should be listening to this statement. It is very important to get in between your teeth and get them cleaned all around. Just using a toothbrush misses a ton of space between your teeth and below the gum line. Chewing gum helps mask the odor, but if you flossed regularly you wouldn't need it.
