Top 5 Surprising Causes of Bad Breath

Welcome to Ansh Dental’s informative blog, where we strive to provide you with the latest insights and valuable knowledge to help you maintain optimal oral health. In this article, we delve into the intriguing world of bad breath, uncovering the top five surprising causes that may be contributing to this common oral concern. Bad breath, medically known as halitosis, can be an embarrassing issue that affects our confidence and interpersonal relationships. However, Dr Shoeb Shaikh and Dr Anisa Shaikh will help you here in exploring the unexpected culprits behind this condition.  We, at Ansh Dental Clinic, aim to equip you with the understanding you need to tackle bad breath head-on and restore freshness to your breath. Let’s embark on this enlightening journey together and discover the surprising causes that could be lurking in your daily routine.

1. Dry Mouth

One surprising cause of bad breath is dry mouth, also known as xerostomia. Saliva helps cleanse the mouth and remove bacteria, but a lack of saliva can lead to bacterial overgrowth and unpleasant odors. Certain medications, mouth breathing, and underlying medical conditions can cause dry mouth. Stay hydrated and consider using saliva-enhancing products or speaking with a healthcare professional for treatment options. Moisturizing Mouthwash: Use alcohol-free, moisturizing mouthwashes specifically designed for dry mouth. These products can help lubricate the oral tissues and provide temporary relief from dryness. Saliva Stimulants: Chewing sugar-free gum or sucking on sugar-free candies can help stimulate saliva production and provide temporary relief from dry mouth symptoms. Avoiding Irritants: Stay away from tobacco, alcohol, and caffeine, as they can further contribute to dry mouth. These substances can be drying to oral tissues and exacerbate the condition.

2. Sinus and Respiratory Infections

Respiratory infections, such as sinusitis or bronchitis, can contribute to bad breath. The mucus produced during these infections can have a foul odor, which can be transferred to the mouth. Treating the underlying infection and maintaining good oral hygiene can help alleviate bad breath caused by these conditions.

3. Gastrointestinal Issues

Digestive issues, such as acid reflux or gastrointestinal disorders, can cause bad breath. Acid reflux allows stomach acids to flow back into the esophagus, leading to an unpleasant taste and odor in the mouth. Treating the underlying gastrointestinal issues, managing diet and lifestyle choices, and practicing good oral hygiene can help combat bad breath caused by these conditions.

4. Certain Foods and Drinks

It may come as no surprise that consuming certain foods and drinks can cause temporary bad breath. Garlic, onions, coffee, and alcohol are just a few examples. Dr Shoeb Shaikh suggests brushing your teeth, using mouthwash, or chewing sugar-free gum can help mask the odor temporarily. However, it’s important to note that these odors tend to dissipate as the food or drink is digested and eliminated from the body.

5. Stress and Anxiety

Stress and anxiety can also contribute to bad breath. When we feel stressed or anxious, our mouths tend to become dry due to increased breathing and reduced saliva production. This dry environment creates an ideal breeding ground for bacteria, resulting in bad breath. Managing stress through relaxation techniques, staying hydrated, and practicing good oral hygiene can help alleviate this symptom.

In addition to addressing the specific causes mentioned above, Dr. Anisa Shaikh, also maintaining a consistent oral hygiene routine is vital for combating bad breath. This includes brushing your teeth at least twice a day, cleaning your tongue, flossing daily, and using mouthwash. Regular dental check-ups are crucial to identify any underlying oral health issues that may contribute to bad breath. 

It’s important to note that if bad breath persists despite addressing these potential causes and maintaining good oral hygiene, consulting with a dentist or healthcare professional is recommended for further evaluation and guidance.


While poor oral hygiene is a common cause of bad breath, it’s important to consider these surprising factors that can also contribute to this condition. Dry mouth, sinus, and respiratory infections, gastrointestinal issues, certain foods and drinks, and stress and anxiety can all play a role in the unpleasant odor. Identifying the underlying cause is essential for effective treatment.

Maintaining good oral hygiene, visiting a dentist regularly, managing underlying medical conditions, and making certain lifestyle changes can help reduce and prevent bad breath. If the issue persists despite efforts to improve oral hygiene and address potential causes, it is recommended to consult with us at Ansh Dental Clinic for further evaluation and treatment options.
