Introduction

Bad breath, or halitosis, can result from various factors. Here are some common causes:

1. Poor Oral Hygiene

Not brushing and flossing regularly allows bacteria to accumulate in the mouth, causing odor. (Mayo Clinic)

2. Food and Drink

Strong-smelling foods like garlic and onions, as well as coffee and alcohol, can contribute to bad breath. (WebMD)

3. Dry Mouth

Saliva helps cleanse the mouth. Reduced saliva flow, often due to medication or mouth breathing, can lead to bad breath. (Colgate)

4. Tobacco Use

Smoking and chewing tobacco can leave chemicals that contribute to bad breath and increase the risk of gum disease. (MouthHealthy)

5. Health Conditions

Underlying medical conditions such as gum disease, respiratory infections, or digestive disorders can cause bad breath. (Healthline)

Conclusion

Identifying the cause of bad breath can help in finding appropriate treatments. Maintaining good oral hygiene and addressing underlying health issues can often alleviate bad breath.
