How do i get rid of bad breath due to tonsil stones? permanently?

Remove the tonsils. The stones are hardened accumulations of food debris in cavities that developed in your tonsils. As long as your tonsils have this abnormality, stones and their effects will persist.

Tonsillectomy will remove your oversized cryptic tonsils, eliminating the "home" for bacteria and food debris, a common cause of bad breath. See an ENT. Most common causes of bad breath is sulfur producing bacteria collecting between teeth where toothbrush can't reach, or on surface of tongue. See a Dentist. Please make appointments with both practitioners.

Tonsils are like a receptacle in the throat that hang down and collect debris from food as well as bacteria. Remove this tissue you don't need and your bad breath will be eliminated also. If you don't want the bad breath to return than you must practice good oral health, brushing, flossing and a healthy diet.
