I have read your problem,Looking to your Oral health,you are not maintaining well.This is not your fault ,because of less knowledge of oral hygiene
care. So go to the dentist
place,He or She will guide you about proper method of brushing (twice a day morning and night)and use antiseptic mouth wash once a day,in addition to this one should clean tongue with tongue cleaner twice a day while we are brushing.Take some good antibiotic, b -complex,antioxidants
,riboflavin(For 1 month) and use antiseptic mouth wash.
