Dental Veneers are cosmetic dental prosthetics that are meant to cover the teeth. It is not exactly a prosthetic, in the sense that it replaces something that was lost (as in the case of dentures, dental bridges and dental implants.).
According to Wrong Diagnosis, one of the causes of mucus stools in children is bacterial overgrowth. Normally there is a certain amount of bacteria in the digestive tract. This is healthy and assists in digestion. But if it grows out of control, then it can contribute to mucus in the stool.
A large increase in the amount of mucus in your child's feces may point to illness, however, especially if it is accompanied by loose stool or blood. The combination of watery stool and mucus may indicate a viral infection or medical problem with the intestines.
