August the 6th is Fresh Breath Day. It is a day when we can think about our breath and how it affects our life and relationships. Bad breath is one of life’s most personal problems. It can make or break a romantic relationship and have an impact on how you do business. Indeed, it can be so personal that even our best friend will not tell us we have bad breath. Would you tell someone that they had smelly breath? On Fresh Breath Day, read up on how you can make sure you have fresh-smelling breath. For many people it’s a simple case of good dental hygiene 1 habits and a healthy lifestyle. Drinking too much alcohol, smoking cigarettes and not brushing your teeth regularly will all make your breath smell.


Around 25 per cent of the population has chronic 2 bad breath, often called halitosis. The older we become, the more likely we are to have it. Bad breath is caused by as many as 600 different types of bacteria. These are found on the gums, cheeks and tongue. Many of us try to hide bad breath with things like mouthwash and breath sprays. These are only short-term solutions. Fresh breath comes from keeping your mouth healthy. This means regular dental check-ups to have your teeth cleaned, flossing, and using a water-jet cleaner every day to remove food stuck between your teeth or under your gums. You also need to scrape your tongue every day. Fifty per cent of bacteria is found on the tongue.
