Bad breath is not only embarrassing; it can indicate that something isn’t right. Bad breath in the morning, while dieting, or accompanying a cold is quite normal and can be addressed with proper oral hygiene, brushing or scraping your tongue, mouth rinses, and Xylitol chewing gum. If your bad breath persists throughout the day or is chronic, it could be caused by a gum or tooth infection, or an improperly fitted oral appliance, and should be addressed as soon as possible. Chronic bad breath could also indicate health conditions such as liver conditions, Diabetes, or chronic sinus infections, so if we don’t find an oral infection and your bad breath persists, please talk to your doctor.
