Bad breath is a very common problem and there are many different causes. Persistent bad breath is usually caused by the smelly gases released by the bacteria that coat your teeth and gums.
However, strong foods like garlic and onions can add to the problem. Smoking is also one of the main causes of bad breath, along with certain illnesses such as nasal and stomach conditions.
Bits of food that get caught between the teeth and on the tongue will rot and can sometimes cause an unpleasant smell. So correct and regular brushing is very important to keep your breath smelling fresh.
The bacteria on our teeth and gums (plaque) also cause gum disease and dental decay. If you see your dentist regularly this will not only help prevent bad breath but will also let the dentist look for and treat these problems.
The most common cause of bad breath is the build-up of bacteria in the mouth. These bacteria coat the teeth, gums, and tongue, and release unpleasant-smelling gases. Other common contributors include strong-smelling foods (like garlic and onions), smoking, dry mouth, and certain illnesses affecting the nose, throat, or digestive system.
Yes, inadequate brushing and flossing allows food particles to remain in the mouth, which promotes bacterial growth. This can lead to plaque build-up, gum disease, and tooth decay - all of which can cause persistent bad breath.
Certain foods such as garlic, onions, spices, and some types of fish contain strong-smelling compounds that can be carried in the bloodstream and exhaled through the lungs. This can lead to temporary bad breath, even after brushing.
Not always. While the majority of cases originate in the mouth, bad breath can sometimes be linked to sinus infections, tonsillitis, acid reflux, diabetes, or liver and kidney problems. If your dentist finds no dental cause, you may be referred to your GP for further investigation.
It can be difficult to detect on your own. One method is to lick the inside of your wrist, let it dry, and smell it. Another is to ask a trusted friend or family member. Your dentist can also assess the cause and extent of any oral odour during a routine examination.
Yes, smoking is a major cause of bad breath. It dries out the mouth, promotes gum disease, and leaves a lingering odour that is difficult to remove. Quitting smoking is one of the most effective ways to improve your breath and overall oral health.
Maintaining good oral hygiene is key. This includes brushing your teeth twice a day with fluoride toothpaste, flossing daily, and cleaning your tongue. Drinking plenty of water and avoiding tobacco can also help. Regular dental check-ups and professional cleans are important to keep your mouth healthy and breath fresh.
Yes, mouthwashes, sugar-free chewing gums, and sprays can offer temporary relief. However, they often mask the symptoms rather than treat the underlying cause. A thorough dental examination can help identify and address the root of the problem.
Yes. In most cases, bad breath can be significantly improved or eliminated by addressing the cause. Whether it's gum disease, dry mouth, or diet-related, your dental team can guide you with tailored advice and treatment options.
