In a healthy person, the deposits will remain clean. If there is a strange color and odor, it can be an early sign of a problem with the lungs and the respiratory tract, kidneys, intestines or hormones.

Moreover, this test can reveal whether you have a bad breath, a problem that many people are unaware of. Simply smell the saliva. If there is a smell reminiscent of ammonia, you may have a problem with the kidneys. If it has a fruity odor, it can be a metabolic disorder, or ketoacidosis.
In any case, do not panic right away, odor does not necessarily mean a disease of the internal organs. It could be a problem with your teeth, cavities or broken teeth.
