How can I tell if I have bad breath?

Lots of small signs can show that you have bad breath. Have you noticed people stepping away from you when you start to talk? Do people turn their cheek when you kiss them goodbye?

If you think you might have bad breath, there is a simple test that you can do. Just lick the inside of your wrist and sniff – if the smell is bad, you can be fairly sure that your breath is too.

Or, ask a very good friend to be absolutely honest with you; but do make sure they are a true friend.
