German magazine "Baby & Family" reported that bad breath in children has several causes, such as tooth decay, tonsillitis, esophageal reflux and diseases of the lining of the oral or throat mucosa such as lip herpes and oral ulcers.
The magazine on the family and children added that bad breath may also warn the child of diabetes, especially if the smell looks like the smell of fresh green apple.
Therefore, you should consult a doctor to determine the true cause of bad breath in children.
To prevent bad breath, the child should wash his teeth twice a day with a child toothpaste that contains fluoride.
