Mixing 1 part of water with 1 part hydrogen peroxide (3%) makes an effective bad breath remedy. This cleanses the mouth and kills the bacteria that cause bad odor. There is another way to use hydrogen peroxide as bad breath remedy particularly if sinus infection is the reason for foul odor. 5 to 10 drops of the same mixture can be dropped to each nostril. Second, the air you breathe is not similar with the air you release when you talk. This is because bad breath causing bacteria originate from the posterior part of the tongue and only pushed forward once you speak. Thus you can never tell if you have bad breath or not only by smelling your own breath. As an alternative to commercial toothpaste, you can use more effective and less expensive toothpaste you can easily make. Just mix 3 parts baking soda with 1 part salt; put it on your toothbrush and brush your teeth like you normally do. Soon, you have a whiter teeth and fresher breath. 3. Use dental floss. This happens when a foreign object is stuck and infects in your child's nose. This creates discharge that is often odorous. 4. Poor oral hygiene practice. Children love to eat but hate to clean their teeth. This results to food particles being stuck in between their teeth. Sweets that contain sugar and dairy products that contain protein, which by the way are two of the most popular types of foods your child want to eat, are broken down by bacteria residing inside their mouth, which produce VSCs. While antibiotics are good options, they are seldom used in curing bad breath. This is largely because the sulfur-producing oral bacteria could in time, get immune with the effects of the antibiotics. Thus, you would only move from one does to another without truly alleviating the condition. Thus, you must go after long term cures. So if you want to stop bad breath, then avoid particular foods and drinks. Quit smoking, stop drinking coffee and soda, and avoid foods that can cause you that foul smell such as cabbage, onion, and garlic. Switch to tea. Eat fruits and vegetables that contain natural fiber. Also, you can make your own toothpaste and mouthwash.
