What are SHARK TEETH and should I be worried?



SHARK TEETH is a term used to describe the situation when the permanent adult teeth are coming up behind the baby teeth before they have fallen out, resulting in two rows of teeth. This usually occurs between the ages of 5-7 years old.

Commonly seen on the lower incisors (bottom front teeth) but can also happen when the upper incisors or primary molars grow in.



How are baby teeth replaced?


As the adult teeth erupt out of the gums it will encourage the roots of the baby teeth to dissolve.

With SHARK TEETH, the roots have not dissolved quickly enough resulting in two rows of teeth.

Typically, it is only a matter of time before the adult teeth naturally replace it hence, in most cases no treatment is necessary.

Encourage your child to wiggle the baby tooth daily (with their finger or tongue) to loosen it to avoid it causing discomfort to your child when eating.

In some cases, you may notice the adult teeth are almost at the same height as the baby teeth and there is still limited movement in the baby teeth or they may become sore, irritable and inflamed. When this happens, you should bring your child in to have it checked at the dentist where they may need a little help to have the baby tooth extracted.


What happens when the baby tooth falls out?


When a baby tooth falls out, the adult tooth will move into the empty spot with the help of the tongue that will push it into place. It can take a few weeks or even a few months to move into position.
