For most people the day to day problem of bad breath is caused by bacteria, especially on the tongue, but also on the
gums. Treatment involves brushing of the
tongue or, more effective, scraping of the
tongue several times a day. Tongue scrapers come as an individual item, but also as an attachment to the common tooth brush. One should also brush the gums.
It has been reported that a chemical, stannous fluoride, can prevent cavities and reduce bad breath odor.
