Food particles often remain trapped between the mouth’s soft tissues and dentures. The patient may not even realize the presence of debris until the dentures are removed for cleaning. Thus, it is advisable to remove the same before sleeping and opt for an antibacterial mouthwash gargle.
Halitosis is common in people who have tonsil stones. That’s because the bacteria that produce volatile sulfur compounds thrive in the crevices of your throat, where food, mucus, and other bacteria have already built up.

Causes of halitosis can originate either inside or outside your mouth. A person with poor oral hygiene maintenance has a higher chance of halitosis than who regularly brushes. Common causes include gingivitis, periodontitis, dental caries, excessive plaque accumulation on teeth and tongue, pericoronitis, or oral ulcers. Food substances having a strong, pungent smell are another common cause. Frequent smoking, alcohol, or caffeine intake results in temporary bad breath. Any diseases or medications that cause dryness of the oral cavity are another contributing factor. Outside the oral cavity, inflammation of the tonsils or sinuses is another important factor that affects the quality of breath. Gastric diseases, especially gastroesophageal reflux, are another cause of halitosis.
Halitosis can be caused by a variety of factors. Poor oral hygiene is one of the most common causes. When we don't brush and floss regularly, bacteria build up in our mouths, leading to the production of foul-smelling gases. Gum disease, also known as periodontal disease, is another common cause of bad breath. The bacteria that cause gum disease release toxins that can contribute to halitosis.
