Bad breath is one of the most common problems that can hinder you from speaking confidently to others. It can be caused not only by poor oral hygiene, but also by many health problems. The main causes are:
Poor oral hygiene: The most important cause of bad breath is not brushing your teeth properly. Bacteria grow in the food debris stuck between your teeth and on your tongue, which releases odor-causing gases.
Dry Mouth: Saliva is what keeps your mouth moist and washes away bacteria. Reduced saliva production during sleep is the reason for bad breath when you wake up in the morning. Not drinking enough water also leads to this.
Diet: Eating onions, garlic, and certain spices can temporarily cause bad breath. This is because the components that mix with the blood when they are digested are released through the lungs.
Gum disease and tooth decay: Cavities, gingivitis, and bleeding gums are breeding grounds for bacteria. This can lead to chronic bad breath.
Other health problems: Bad breath is also a symptom of sinusitis, tonsillitis, gas problems, diabetes, and liver and kidney diseases.
