If I remember correctly easy child's wisdom teeth came in when he was 17.5 We were at the dentist last week and they showed me the xrays. The wisdom teeth are right there. Look the same as the other teeth, but they told me it hasn't broke the gum yet. Top look like they are coming in striaght, but they could make a turn. Bottom ones are sideways...facing his last teeth. It is going to go right into the side of his last tooth. Does anyone remember or have experience with this? Can these teeth lay dormant for a long time? 6 months or more. A year?
