Luckily Premier Family Dental has a course of action to take to actually prevent tonsil stones from showing up in the first place. We recommend that every morning and night you use mouthwash. Also try to avoid foods like popcorn, sesame seeds, and spinach. These have a high chance of leaving food particles stuck in your tonsils. Thus eventually forming tonsil stones.
Managing respiratory-related bad breath involves treating the underlying respiratory condition. This may involve taking prescribed medications, using nasal sprays or rinses to clear out mucus, or practicing good respiratory hygiene by covering your mouth and nose when coughing or sneezing.

When to See a Doctor for Halitosis: Serious Underlying Causes and Treatment Options
Always make an appointment with a medical professional at the first signs of illness, as breath that smells like ammonia will not subside until the underlying cause is treated. Until then, brushing and flossing daily, and cleaning your tongue can help fight the buildup of bacteria in the mouth. As well, drinking lots of water, avoiding tobacco products, and chewing sugar-free gum can mask any unpleasant odours.
