If a reversal is carried out within 10 years of your vasectomy, the success rate is about 55%. This falls to 25% if your reversal is carried out more than 10 years after your vasectomy. Even if a surgeon manages to join up the vas deferens tubes again, pregnancy may still not be possible.
A RealAge answered. The primary cause of tooth erosion is acid in citrus fruits and other foods. Stomach acid is also a factor, so people who have acid reflux and those who vomit repeatedly because of eating disorders are susceptible to tooth erosion. Sometimes, chlorine and other chemicals can cause erosion.
Excessive exposure to fluoride causes a defect of the tooth enamel known as dental fluorosis. In its most severe form, dental fluorosis is a seriously disfiguring condition, marked by brown and black staining of the teeth, often with extensive pitting, chipping, and crumbling of the enamel.6(2):128-32. âExtremely heavy intake of water with a fluoride content of about 0.5 ppm during the early years of tooth development has produced severe to mild fluorosis of the teeth in the family members affected by hereditary pituitary diabetes insipidus.â.
