I can't emphasize how important this is.
If you do have it and don't know, could be a reason a girl didn't take your calls.
and if you do, I highly recommend the Dr Katz line. Therabreath toothpaste and mouth rinse.
I used to have halitosis, ($hit breath) haven't had it in years thanks to this product.
one of the reasons I dropped a recent plate...she had terrible breath upstairs and downstairs.
