The rotten egg smell associated with sulfur burps comes from hydrogen sulfide gas. When bacteria in the mouth and digestive system break down food, new compounds form. Hydrogen sulfide is one of the byproducts of digestion.

How do you get rid of Sulphur breath?

The best way to neutralize sulfur gas is to use a zinc-ion based mouth rinse. However, really getting rid of halitosis means moving beyond simply neutralizing sulfur gas to blocking it from returning. For that, you'll need activated zinc-ions.

What do sulfur burps feel like?

Sulfur burps are burps that smell like rotten eggs. Most burps come from swallowed air that gets trapped in the esophagus and burped back out, without ever reaching the stomach. But some of the air you swallow goes through the esophagus into the stomach, where it mixes with digestive gases before being burped back up.
