Common reasons for ongoing bad breath
Persistent bad breath can have many causes, including dental plaque, gum disease, dry mouth, oral infections or other medical factors. A flavored supplement may mask odor temporarily without addressing the underlying cause.
What to do first
- Maintain regular brushing and interdental cleaning.
- Discuss tongue cleaning with your dentist if appropriate.
- Drink adequate water and check for dry mouth.
- Seek a dental assessment if bad breath persists.
What about claims that probiotics fix breath?
Some probiotic strains have been studied for oral outcomes, but it is not established from the sources reviewed that ProDentim reliably resolves halitosis. Avoid relying on testimonials as proof of effectiveness.
