The Chilean Journal of Pediatrics published a study on how cavities can be a contagious disease.
According to the study, this condition has been determined to be a communicable disease, which is usually spread from one person to another through the saliva that is expelled from sneezing, in which the bacterium Streptococcus Mutans (SM) plays a fundamental role in its transmission, a microorganism that is specifically associated to this pathology.
This bacterium is generally found in the gums, teeth, saliva, tongue, mucous membranes and in the spaces between the teeth. It is more common in children, the elderly and in immunocompromised people.
According to the CES University Journal of Dentistry in Medellín, Colombia, this bacteria originates from changes to the natural balance of microflora in plaque. These changes can be caused by local environmental conditions and by the effects of new microorganisms being introduced.
A necessary balance
People need microorganisms for the body in general to function properly. Some bacteria such as SM should be controlled with good oral and interdental hygiene by using a toothbrush, floss, toothpaste and mouthwash.
