Question

results in bad breath, bleeding of gums and indigestion

Answer 1

90% of bad breath comes from proteins broken down in your mouth. When bad breath is caused by oral problems, it usually smells like rotten eggs. This is caused by the breakdown of cysteine at the front of the tongue or on the gums. It’s a sign of poor oral hygiene.

More rarely, dental bad breath can be a fecal odor like odor from the gums or the top of the tongue. This is caused by imbalances within the mouth or from protein breakdown on the gum tissue or tongue.

If you have bad breath, your first step is a dental exam and good oral hygiene. However, the mouth-body connection means that other bad breath smells can tell you about problems elsewhere in your body.
