Bad breath is usually caused by poor oral hygiene habits, infections that occur in the mouth, unhealthy habits, such as smoking and alcohol intake, and foods that you eat. Other culprits include dry mouth, respiratory tract infections, systemic diseases such as diabetes, kidney, liver and lung disease and gastrointestinal issues, which may include acid reflux and other stomach digestion problems.
In general, the best way to prevent bad breath is to brush and floss every day. But there are also other techniques to freshen your breath, which your dentist or doctor can discuss with you. Always make sure you’re practicing great oral care habits. Brushing twice a day and flossing daily will help to control plaque development and use of a tongue scraper will help control odour causing bacteria that form on the tongue. Use of floss is important to keep the spaces in between your teeth clean. Regular dental visits twice a year for a check-up and professional cleaning are also excellent steps.
