Hello! You need to get your professional dental cleaning done once in 6 months. Always remember if hard deposits ( tartar) are present in your oral cavity then even if you brush 5 times in a day it won't help. Please visit Your dentist and they would guide you after proper dental consultation ! Remember not to keep popping medicines for any problem! Get a proper diagnosis and treatment !

Poor oral hygiene is not the only cause for halitosis it may be due to prolong medication or drug therapy, long Fasting, upper respiratory tract infection, gastrointestinal disorders and many other reasons.. If ur oral hygiene is good and u already visited dentist.. then u need to take physician opinion also..
