I have bad breath problem. Consulted with many dentists but to no avail. As per them I don't have any problem with my teeth or gums. My problem lies in my stomach. They advised me to consult with gastroenterologist. I brush twice daily, have used various kind of mouth wash but problem still remains the same. Because of this problem my self-confidence is decreasing. Please do help. This problem arise 3-4 years back. I didn't had any bad breath problem in my childhood.
