This alternative product may be questionable, and never heard of using it for for oral thrush treatment, and would wait for a proper diagnosis by the doctor, especially after surgery, if it is thrush, and not something else. Thrush can be caused by dry mouth, medication like antibiotics, poor immune system, nutrition, etc, and is usually treated with diflucan (flucomizole), clotrimizole, nystatin rinses, salt water rinses. Some use probiotics, and avoiding sugar, alcohol, yeast and princessed food products, which feed thrush, but contact the doctor. If you ever think the doctor should be called, it is usually warranted. Good luck.
