Part Shark, Part Human

Typically, when permanent teeth are coming in, they erupt directly beneath the baby teeth, causing those baby teeth to become loose and ultimately fall out. However, sometimes this is not the case, and the permanent teeth will erupt directly behind the baby teeth, and you will then find two rows of teeth in the mouth. This is sometimes referred to as “shark teeth” since sharks typically have two rows of teeth in their mouths.

Have no fear! This is a common condition and often occurs in the lower front teeth of children. This condition does not require immediate attention and does not cause an issue for the child, although it may seem as though it does. Whether a dentist needs to assist your child, or your child can wiggle it out themselves, the permanent teeth will begin to shift into a better position from the force of the tongue when eating and talking. Thankfully, the lip will prevent the teeth from moving too far forward.

Did you know?

Typically, sharks can have 15 rows of teeth on the top and bottom, but most only have about five rows. In some species, sharks have been known to have up to 50 rows of teeth: that’s 350 at one time! These types of sharks can average around 50,000 in their lifetime. However, shark teeth do not have roots, which make them weak, so they fall out easily. Unlike humans, a shark’s tooth can be replaced in a day!
