Over the years I have gone to several different dentists for help with halitosis. I have always gone for two teeth cleanings a year and have brushed, flossed and rinsed twice a day. I have searched the internet and asked the dentists for recommendations. I've tryed Therabreath, Closystem, profresh and baking soda/peroxide. They seem to all work for a while and then do not. Profresh has probably worked the best, but not for long. All of these products say if they don't work that you have a gastroenterology problem.
Please give me some advise.
