Teeth are made up of three layers of varying densities

  • Enamel- a hard protective outer layer
  • Dentine – a second protective layer covering the nerve of the tooth
  • Pulp – also called the nerve, is the soft middle part of the tooth that has a blood supply and nerve endings.

Everybody gets two sets of teeth in their lifetime. Your first set is called milk teeth. It begins to sprout when you are 6 months old. By the time you are two and half, all 20 have grown in. By the time you turn 6, your milk teeth begin to fall out. This is because your permanent set is on its way.

Since your jaw grows alongs with the rest of your body, you have place to accommodate the 32 teeth in your permanent set.

Even though your milk teeth are only temporary, it is important to care for them, because the healthier and stronger your milk teeth are, the better it will be for your permanent set.
