Halitosis treatment could be done once you know the exact cause of the condition. If you are into bad habits like smoking and drinking alcohol, you might want to stop those bad habits. Good oral hygiene would eventually take away bad breath. If bad breath persists after having done good oral hygiene and breaking bad habits, you might want to see a hygienist for a better look at what could cause your Halitosis. Some causes could be medically connected and the doctor could be the one that can help you out.
