MY CHILD HAS TWO ROWS OF TEETH
Q My six-year-old daughter has started losing her milk teeth. But before the tooth falls, her new tooth emerges behind the milk tooth. This happened with her lower left central and now it is happening with the lower right central too. Is this going to cause her problems?
AThis condition of the permanent teeth erupting behind the baby teeth is fairly common.
The permanent tooth normally erupts below the baby tooth and as it erupts, it resorbs the roots of the baby tooth, which becomes loose and eventually fall out. But in some cases, the permanent tooth erupts behind the baby tooth and thus the root of the baby tooth are not resorbed, giving the appearance of two rows of teeth. Check if the baby tooth is shaky and encourage your child to wiggle it until it comes off. If the tooth is firm, you may have to get it removed.
Usually the permanent tooth moves forward, due to tongue pressure, into the correct place. If there is crowding, this might not happen and orthodontic treatment may be needed.
