Bad breath is a common problem caused by various factors, including food choices, smoking, and poor dental hygiene. Fortunately, you can do a few things to help manage bad breath at home. Improve your oral hygiene. Brushing twice a day and flossing once daily can help remove food particles and reduce the risk of bad breath. In addition, do not forget to brush or scrape your tongue to remove any plaque build-up. Diet modification. Avoid foods that are high in sulphur, such as garlic and onions. These can cause bad breath. Coffee and alcohol can also contribute to bad breath. Cutting back on these foods or avoiding them altogether can help improve the smell of your breath. Drink plenty of water. This will help flush out your mouth and remove any food particles that may be stuck between your teeth. It also keeps your mouth hydrated, preventing dry mouth. Stop smoking. Patients who smoke are left with chemical compounds in their mouth that interact with the saliva causing bad breath. Cessation of smoking can greatly reduce bad breath. Following these simple tips can help you control bad breath and enjoy fresh-smelling breaths all day long.
