Hi
With your query, bad breath could be of many reasons either due to systemic diseases or local/dental factors. IN order to start with the treatment one have to rule out the cause to start with treatment. Since you have mentioned with no systemic health related issues it would be better you visit your dentist and get his opinion regarding the same after thorough examination of your teeth and oral structures and start with the treatment till t hen you can use mouthwashes for temporary relief.Hope this helps you.

Thanks for your query, i have gone through your query. The bad breath could be because of the deposits over the teeth causing gum infection or it can be because of the pus discharge from the gums or respiratory tract infection. consult a oral physician and get yourself examined to rule out the above said conditions. Get your teeth cleaned once and use mouth washes to rinse your mouth. i hope my answer will help you, take care.
