Halitosis, or bad breath, can be cured with treatment of the underlying causes. Bad breath, or halitosis, is characterized by an unpleasant odor of the mouth. Causes of bad breath include food, tobacco products, poor dental hygiene, health problems, dry mouth, oral infections, dental problems, or medications.
Clean your tongue: If you still experience bad breath after brushing, there could be food residue on your tongue. Try a tongue scraper (an inexpensive tool found in drugstores) or try brushing your tongue with your toothbrush to solve this issue and prevent bacteria buildup.
Possible causes of halitosis
Food. The breakdown of food particles in and around your teeth can increase bacteria and cause a foul odor
Tobacco products. Smoking causes its own unpleasant mouth odor
Poor dental hygiene
Infections in your mouth
Gum disease can also contribute to foul-smelling breath. It's caused by neglecting oral hygiene. Neglecting your oral health also leads to an overgrowth of bad bacteria in the mouth, which can cause the odor on your breath.
If you're not brushing or flossing effectively, food particles can get stuck in crevices on the surface on the tongue, between the teeth, or along our gum tissue. The bacteria in your mouth will break down those food particles, which releases the lovely bad breath come morning time.
Drink plenty of water throughout the day to refresh your breath. Water is less likely than other beverages to upset your stomach or weaken your LES. It also helps wash away bacteria that can lead to bad breath.
