Your child regarding healthy habits of eating and cleaning. What you have to do is to advise him to take care of his mouth and teeth in an appropriate way. Ice creams, chocolates, candies, junk food and sweets are a center of attention for children. This food generates germs in their mouth and due to bacterial activities in mouth, nose and teeth, children face the problem of bad breath.
Most children will experience morning bad breath. This is because when sleeping saliva is not produced anymore and the muscles of the mouth are relaxed. As children sleep a lot they are developing areas inside their mouth that end up as saliva free, more particularly oxygen free. These areas are perfect for housing anaerobic bacteria that cause bad breath with producing waste products that are actually made out of very smelly volatile sulfur compounds (also known as VSCs), which usually smell like rotten eggs.
Respiratory problems: Bad breath results from mucous discharge from runny nose, secretions dripping down to the throat and on to the tongue. The secretions are excellent site for odor causing bacteria, which produce sulfur compounds. Sinus infections also cause halitosis. Asthma is another cause for bad breath. Enlarged adenoids may lead to mouth breathing in asthmatic patients causing bad breath.
Dry mouth: Decreased flow of saliva results in dry mouth. Saliva is essential for cleansing the teeth and mouth and destroying oral microorganisms. Mouth breathing also causes dry mouth, which in turn causes Halitosis.
Allergy, cold, temperature, etc. can also cause bad breath. Some children have the habit of trapping some food particles at the backside of their teeth. If this food remains in their mouth for a considerable period, it creates a ground for bacteria to play their toxic role. Make sure that your child does brush his teeth before going to sleep. When our body is suffering with any disease or allergy, our mouth turns out to be dry and in a dry mouth suit bacteria very much.
The habit of oral hygiene needs to be instilled in children while they are growing up. It's fairly well established that children are not necessarily fastidious in keeping their teeth and mouths clean, and the presence of old food may provide a good breeding ground for the bacteria that cause decomposition and smelly breath. Children should always be encouraged and taught to maintain the highest standards of oral hygiene, as this is a habit that they will carry with them through their lives.
Maintain oral hygiene by regularly brushing and flossing your teeth. Since halitosis occurs at the back of the tongue, clean the surface of the tongue daily with a soft bristled brush. Mouthwash is useful. Children should drink lot of sugar free fluids to avoid dry mouth.
