Two nights ago I asked Keegan to open his mouth so I could check if he had given his teeth a good brush before bed. I was surprised to spy an adult tooth emerging from his gum from behind his baby teeth down the bottom.
According to numerous internet sources, it is a very common condition called "shark's teeth". Some children around six years old develop two rows of teeth when the permanent teeth come through before the baby teeth have fallen out. The new teeth will push forward on the baby teeth, usually causing them to fall out within a few weeks. The adult tooth then moves naturally into place.
We will encourage Keegan to wobble his two bottom teeth to loosen them and help them to fall out soon. I'm hoping he won't need a special trip to the dentist.
