What Your Has Smelly

1. Poor dental hygiene. This is the most common cause of bad breath. When you don't brush and floss your teeth regularly, bacteria can build up and cause your breath to smell.

2. Dry mouth. Saliva helps to keep your mouth clean and free of bacteria. When you have dry mouth, your saliva production decreases, which can lead to bad breath.

3. Gum disease. Gum disease is a serious infection of the gums that can cause bleeding, swelling, and bad breath.

4. Tonsillitis. Tonsillitis is an infection of the tonsils, which are two small glands located at the back of your throat. When you have tonsillitis, your tonsils can become swollen and infected, which can cause bad breath.

5. Sinus infection. A sinus infection is an infection of the sinuses, which are four air-filled cavities located behind your forehead, eyes, and nose. When you have a sinus infection, your sinuses can become blocked and filled with mucus, which can lead to bad breath.

6. Acid reflux. Acid reflux occurs when stomach acid backs up into your esophagus. This can cause a burning sensation, regurgitation, and bad breath.

7. Certain foods. Some foods, such as garlic, onions, and coffee, can cause bad breath.

8. Smoking. Smoking cigarettes, cigars, or pipes can damage your teeth and gums, and it can also lead to bad breath.

9. Medical conditions. Some medical conditions, such as diabetes, kidney disease, and liver disease, can cause bad breath.

If you have bad breath, it's important to see your doctor or dentist to determine the cause. Treatment for bad breath will depend on the underlying cause.
