Bad breath, also known as halitosis, can be an embarrassing problem.
1. Poor Oral Hygiene
- Plaque Buildup: When you don't brush and floss regularly, plaque (a sticky film of bacteria) accumulates on your teeth and gums.
3 These bacteria produce foul-smelling compounds.4 - Food Particles: Food particles can get trapped between your teeth, on your tongue, and around your gums.
5 If not removed, they decompose and contribute to bad breath.6 - Tongue Coating: The uneven surface of your tongue, especially the back, can trap bacteria and food debris, leading to bad breath.

2. Dry Mouth
- Reduced Saliva Production: Saliva helps cleanse your mouth by washing away food particles and bacteria.
8 When your mouth is dry (xerostomia), it can't perform this function effectively, leading to bad breath.9 - Causes of Dry Mouth: Dry mouth can be caused by certain medications, medical conditions (like Sjögren's syndrome), dehydration, or mouth breathing.

3. Gum Disease
- Gingivitis and Periodontitis: Gum disease (ranging from gingivitis to periodontitis) is an infection of the gums that can cause bad breath.
11 Bacteria accumulate in the pockets between your teeth and gums, producing a foul odor.12
4. Diet
- Strong-Smelling Foods: Eating foods like garlic, onions, and certain spices can temporarily cause bad breath.
13 These foods release sulfur compounds that are absorbed into your bloodstream and exhaled through your lungs. - Low-Carb Diets: Some low-carb diets can lead to bad breath due to the metabolic processes involved in burning fat for energy.

5. Medical Conditions
- Sinus Infections: Sinus infections can cause postnasal drip, where mucus drains down the back of your throat.
15 This mucus can be a breeding ground for bacteria, leading to bad breath.16 - Tonsil Stones: Tonsil stones are small, calcified deposits that form in the tonsil crevices.
17 They can trap bacteria and food particles, causing bad breath.18 - Gastrointestinal Issues: In some cases, gastrointestinal problems like acid reflux or GERD can contribute to bad breath.

6. Tobacco Use
- Smoking and Chewing Tobacco: Tobacco products not only stain your teeth and increase your risk of gum disease but also contribute to bad breath.

7. Other Factors
- Dentures: Dentures that are not cleaned properly can harbor bacteria and food particles, causing bad breath.
21 - Oral Infections: Infections in the mouth, such as tooth decay or abscesses, can also lead to bad breath.
