When the fourth dimension is right, our bodies have special cells that slowly eat away the roots of the teeth. As the roots get shorter, the teeth start to become loose. Finally, most of the root disappears and the tooth falls out!
Non long after, a new adult tooth will start to peek through the gap left by the baby tooth.
Adult teeth tin can look a flake funny at the start – they are usually a flake yellower, tin have bumps and grooves and are of class much bigger. They as well have much longer roots. Adult teeth are made this way so that they are strong enough to terminal our entire lives. You'll be chewing food for many, many decades to come up. That'south a lot of food to chew through!
The right teeth for the right chore
People become two sets of teeth because this is what works all-time for the way nosotros consume and grow.
Animals are simply the same – they accept teeth that lucifer the way they eat and grow. Rats like to use their front teeth to nibble and gnaw at food and so have forepart teeth that keep growing. Alligators can make new teeth whenever they need and sharks have rows of teeth that they replace all the time. They become a lot more sets of teeth than united states.
But people only accept ii sets of teeth and then we have to do our best to look after them by brushing twice a 24-hour interval with toothpaste and avoiding sweet drinks and snacks.
