Hi I have gone through your complaints. This can be a condition called halitosis
. Care should be taken from the starting of day with careful brushing for at least 4 to 5 min. Use a better paste for brushing and do it just before sleep also in the night. After consuming any food you need to gargle your mouth for at least 1 min daily. Just check whether you have any caries tooth or bleeding gums
. Check for any gingivitis
. If it is still not getting controlled you need to use mouth washes like rexidine mouth wash.
Thank you. Good day.
