Hi,
Thanks for asking the query,
Bad breath usually occurs due to poor
oral hygiene, plague and calculus deposition, GIT problems, respiratory problems, sinusitis,
mouth breathing, faulty restoration causing plague and calculus deposition.
I would suggest you to go for symptomatic treatment of complete mouth scaling and polishing.
Use
chlorhexidine mouthwash gargles twice daily.
Brush tooth twice daily with a soft bristle toothbrush.
Develop a habit of using dental floss and interdental cleaners.
Also get your blood sugar level checked.
Take a complete balanced diet, drink plenty of fluids.
Clean the tongue with a tongue cleaner.
Hope this helps out.
Regards..
