Mouth odor can come from several areas. If it has been a while since your last cleaning it may be time. If you are not flossing you could be building up bacteria that cause bad breath. Your tongue harbors bacteria and should be brushed along with your teeth. You may have some old leaking dental work that needs to be changed. Retained tonsils, sinus problems, allergies, esophageal reflux, diabetes, alcohol, coffee, some foods, fasting, and dehydration can all cause bad breath.
If you have persistent mouth odor after following the advice above, you may contact the Fitzgerald Dental Center of Dallas to schedule a dental appointment for a check up and cleaning. We will attempt to determine the cause, and a solution to your mouth odor.
