Tooth Development

You’d be surprised at the time your body puts into developing your smile!

  • Although they won’t pop through until your baby is closer to six months old, teeth begin forming in the second trimester of pregnancy.

  • Once they do begin showing, you can expect to see parallel growth, meaning, teeth on the left will grow synchronously with the same teeth on the right.

  • Permanent teeth take longer to grow than primary teeth. While most permanent teeth begin to show at around six years of age, it can be five years before they’ve all come through.

  • The top or crown of the tooth forms and emerges first. Even if it’s broken through the gum the root of the tooth may still be developing underneath.


Parts of The Tooth

Teeth are composed of four different types of material, each of which serves a different but important purpose.

  • Enamel – Enamel covers the entire surface of the tooth that protects it from damage and wear. Enamel is harder than bone and made up of phosphorus and calcium.

  • Dentin – Dentin the layer beneath enamel. Dentin looks very similar to bone. It is less resilient than enamel, and at risk for decay should the enamel wear away.

  • Cementum – Cementum covers the tooth’s root. Cementum is yellow and covered by the gums. Should you not brush and care for your teeth properly gums can recede exposing cementum to harmful bacteria.

  • Pulp – The pulp of the tooth contains the nerves that send your teeth helpful signals.


Types of Teeth

There are five different types of teeth, each aiding in chewing food in a different way.

  • Incisors – You have eight incisors (four on top, four on bottom) in the front of your mouth. These are the teeth that help you take bites of food.

  • Canines – Your four canines are your sharpest teeth. They are intended to rip and tear pieces of food off.

  • Premolars – Premolars are used for grinding the food down to a more easily digestible substance. You have eight premolars, four on either side of your mouth.

  • Molars – Molars, like premolars, are used for grinding food and chewing.

  • Third Molars – Or wisdom teeth.These are the last teeth to develop. Some people wind up not having them at all. They often cause crowding in the mouth and are removed.
