Comment: I had a patient who used (gargled) Listerine mouth wash at least 3 times daily for over 20 years, and he developed tongue base squamous cell carcinoma. He had no other risk factors (ie smoking or alcohol). In my opinion, this cancer was definitely caused by the mouthwash. Too much of a good thing can sometimes be bad. He is doing well after surgery, radiation, and chemotherapy.
