But if the adult tooth erupts somewhere else — usually behind the baby tooth — both adult and baby tooth can be present at the same time, with one behind the other.
This is effect is also referred to as shark teeth since sharks have two rows of teeth.
This usually looks concerning but it’s very common and rarely becomes a problem.
If the baby tooth is moving or loose and the adult teeth are coming in, I would wait and see if the baby teeth come out.
If the baby teeth are not loose and both baby and adult teeth are at the same height, then I’d recommend scheduling an appointment with your family dentist or a pediatric oral surgeon to discuss whether the teeth need to be removed, however, the dentist will likely want to observe them at first to wait to see what happens.
I wouldn’t worry but do check the height of the teeth to see if they’re wiggly or not to determine whether you schedule an appointment sooner rather than later.
Hope that helps!
