Answer

I do not see how blood in his urine could have anything to do with his mouth. Blood in urine is usually indicative of a urinary infection (most likely bladder or urethra). You didn't indicate what symptoms were present in his mouth. You may have a mother on your hands that is angry about your relationship with your fiancee and is using him to get revenge. However, it is important to put the child's health first. With this in mind, I would recommend taking the boy to a doctor for a check up to determine if he does in fact have an infection in his mouth. If he does, the doctor can give him medicine to take care of him. If not, you will be able to tell his mother he was checked and given a clean bill of health. The doctor's office can also do a urine test to determine if he has blood in his urine. Both symptoms can be checked with one visit.
