Thanks for asking the query,Bad breath
occurs due to plenty of reasons like poor oral hygiene
, plague and calculus deposition, GIT disturbances, Sinusitis
, tongue coatings, decayed tooth, oral pathological conditions.
I would suggest you to visit to a Dentist
and get a checkup done.
Go for complete mouth scaling and polishing every six months.
Develop a habit of brushing teeth twice daily, use interdental toothbrush, floss.
Use antiseptic mouthwash rinses twice daily.
Maintain a very good oral hygiene.
If there are any decayed tooth then get it restored.
Avoid alcohol consumption, smoking.
Hope this helps out,
