My 3 year- old son has a bad breath. But he brushes his teeth 3x a day. He said his head is aching but no fever. Why does he have a bad breath?
Dental Cleaning. When we brush and floss our teeth several times a day their are areas we will miss. Plaque accumulation with bacterial action results in gum irritation and a sulfur-like compound that results in bad odor. Professional dental cleaning is needed average twice per year. Bad odor can also result from certain foods, gastric or digestive conditions or certain illnesses. Head ache is probably unrelated.
