Having bad breath is always one of those embarrassing situations we never want to find ourselves in. But what exactly causes the unpleasant odours?
While many of us think it's simply down to smelly foods that we consume, there are plenty of other reasons why we could be experiencing bad breath.
Foods that make your breath smell: Cosmetic bad breath is the most common cause, superficial bad breath that can usually be eliminated by using sugar-free chewing gum, tooth brushing or mouthwash. 'Highly smelling foods, such as onion and garlic, and drinks such as coffee, all cause cosmetic bad breath,' says Karen Coates, Dental Advisor at the Oral Health Foundation. 'And of course smoking is a big cause of stinky breath.'
Poor oral hygiene: But the biggest cause of bad breath is bacteria in your mouth, caused by insufficient tooth brushing. 'Food, debris and plaque can get stuck in your around the teeth which will eventually break down causing bad breath gases,' Karen tells us. 'The gases produced by the array of nasty bacteria living in your mouth feed off leftover food and sugars and release the bad smell,' adds Dr Miguel Stanley. 'That's why flossing is incredibly important.'
Dehydration: Often overlooked, dehydration is another big reason your breath smells. 'Being dehydrated means that you do not produce as much saliva as usual,' Karen tells us. 'Saliva is the mouths natural way of fighting bacteria as it has antibacterial properties. Without it means that the bacteria, which cause bad breath, can grow rapidly.' So ensure you're drinking enough water a day to curtail smelly breath too.
What health problems are associated with bad breath? Dr Stanley stresses that not all bad breath problems are an indicator of bad teeth. 'If you have sweet, fruity smelling breath for example, it could mean you have diabetes, while ammonia smelling breath could mean kidney issues,' he tells us. It's important to rule out any oral health problems from your dentist before seeking other medical advice. If bad breath persists when you are certain you have no dental issues, Dr Stanley recommends visiting an ear, nose and throat specialist to see if you have any sinus problems, and also with a gastroenterologist to make sure everything is okay with the digestive tract.
