Therabreath doesnt work at all and i bought alot of his products, waste of money. Dr.Katz is all sincere talk and no genuine action.
Breeze didnt work for my bad breath either. i got the breeze kit that included 2 different toothpaste, nasal spray, nasal saline spray, mouthrinse, etc.
profresh didnt work for me as well.
tri-oral was the best of all for me though it didnt cure my bb, but it is very trong so it makes your tongue feel numb with chemical taste.
i think Therabreath and Profresh was the least active product in treating my bad breath.
