Dear Lybrate user, Bad breath
may be a warning sign of gum disease due to plaque and tartar build-up. Kindly visit your dentist
a check up done for any cavities
or gap between teeth where food can get stuck. With the help of professional scaling and polishing your condition will improve. You should maintain good oral hygiene by brushing your teeth twice daily, use of mouthwash twice daily, clean the back of your tongue using a tongue cleaner. If the condition still doesn't improve then kindly visit a physician for stomach problems.
