There are bad habits you need to correct immediately to avoid increasing harmful bacteria that lead to bad breath, such as: skipping meals, cutting down on carbohydrates, eating onions or garlic...
Drink alcohol
Alcohol causes a decrease in healthy bacteria and an increase in bacteria that cause tooth decay and gum disease. These harmful bacteria produce sulfur compounds that cause bad breath.
Alcohol also dries out your mouth. Saliva not only keeps your teeth moist, it also helps remove plaque and bacteria from the surface of your teeth. Drink plenty of water throughout the day (about 8 glasses) to stimulate saliva production, which helps clean your mouth naturally. In addition to alcohol, caffeinated drinks and spicy foods can also cause this condition.
skip meals
Skipping meals can cause bad breath because your mouth doesn’t produce enough saliva to clean up food particles and control sulfur compounds. Without enough saliva, bacteria will multiply more and make bad breath worse.
Eat a ketogenic diet
Ketogenic is a high-fat, adequate-protein, low-carbohydrate diet used in medicine to treat epilepsy. When you cut carbohydrates and increase protein, your body starts burning fat for energy. This process creates compounds called ketones, which cause bad breath. In this case, chewing sugar-free gum also helps improve the condition.
Ketone breath often smells like acetone—the same chemical used in nail polish remover. However, it can also have a fruity odor.
Eat smelly food
Spices, garlic, onions, and pickles cause bad breath. The pungent smell of these foods can disappear after an hour or two of brushing your teeth properly. If your breath smells after eating onions, drinking green tea may be a suggestion. Green tea contains polyphenol compounds that can destroy sulfur compounds, reducing bad breath. Pineapple, apple, orange, cucumber, and cherry help eliminate bad breath, and their high vitamin C content reduces the risk of gingivitis. They stimulate saliva production to clean the mouth and remove trapped food particles.
