The diagnosis of niacin deficiency is based on the diet history and symptoms. Measuring a by-product of niacin in urine can help establish the diagnosis, but this test is not always available. The diagnosis is confirmed if niacin relieves symptoms.
The survey of primary caregivers revealed that, for those children who had seen a dentist â and 34% had not â the average age at the initial visit was 2.6 years. The American Academy of Pediatric Dentistry (AAPD) recommends that a child go to the dentist by age 1 or within six months after the first tooth erupts. Primary teeth typically begin growing in around 6 months of age.
(If your child still doesn't have any teeth by 15 to 18 months, schedule a visit with a pediatric dentist.) Teeth generally appear one at a time over a period of months, and often â but not always â in this order: First the bottom two middle teeth, then the top two middle ones, then the ones along the sides and back.
