Almost everyone experiences bad breath once in a while but for some people, bad breath (halitosis) is a daily problem. Halitosis affects one in four people, but many of them may not be aware of their own smelly breath and may only come to learn about it from a relative, friend, or co-worker.
Bad oral hygiene
According to Dr Thomas Munyao Junior, a paediatric and orthodontic dentist, poor oral hygiene is a common cause of halitosis.
