How can i get my six year old help for her bad breath?

See DR: There are many different causes of halitosis, or bad breath. You will need to see your dr to sort through some of these. They include dental issues, such as gingivitis, sinus problems, tonsillitis, oral infections, and certain stomach problems. Occasionally, no source is identified, and local management is recommended-mouthwash, frequent brushing, and scented, sugarless gums.

Diet: After a dental exam reveals no bacterial infections, then the most likely cause may be food allergy, especially lactose intolerance. Try going off milk & cheese, and add probiotics to the diet.
