I have embarassing bad breath, what can i do?

Depends: Bad breath can come from one of three places. Certainly plaque build up and periodontal disease is one. The others are sinuses and stomach problems. What to do depends on the cause. If it is from your gums and plaque, have a good celaning at your dentist. Treat any disease such as periodontal disease or cavities and have great home care.

You can also be checked for tonsil stones and be referred to an ENT if needed.
