Hello.
I certainly understand your concern.
Check with your dentist for any cavities, spaces between your teeth,impacted wisdom teeth,gums if everything is fine then,Check your gut health if that's fine ,then meet an ENT specialist for sinusitis and bronchitis.
Rule out the cause and you will get better results.
If your constantly using mouth wash it will make your oral cavity more dry,and that ll lead to bad breath.
