However, improper oral hygiene is not the only cause of halitosis formation. This troublesome condition may also occur as a result of using dentures or braces. The hard-to-reach areas around these fillings are difficult to reach with a toothbrush or dental floss, which is why bacteria that cause bad breath thrive there. Other common causes of halitosis include: diabetes, kidney disease and thyroid disease, infections of the sinuses, throat or tonsils, dry mouth, improper eating habits (drinking large amounts of alcohol, smoking, starving oneself), taking certain medications (mainly antidepressants, painkillers and diuretics).
Keep your saliva flowing by eating healthy foods that make you chew. Carrots and apples need a lot of saliva. You can also chew sugar-free gum or suck on sugar-free candies. If you still don’t have enough saliva to keep your mouth moist, your dentist may suggest artificial saliva.

These keep the gums and teeth clean as well as the beta carotene in carrots can boost up oral hygiene. You can also remove a tonsil stone with the back of the toothbrush. With the non-bristle part of the toothbrush, gently free the tonsil stones from the throat. This also helps to remove the bacteria as well as prevent further stones from developing. Due to its acidic properties, apple cider vinegar works by breaking the stones into smaller pieces and finally rinsing them off completely. But first, remember to dilute with it water before gargling. Taking it raw can cause a burning sensation in the mouth and throat.
However, there is also the possibility, albeit less common, that it originates outside the oral cavity. It is essentially due to disorders of the respiratory tract, the digestive system, or kidney or liver pathologies.
