Do You Know Your Teeth? | Indianapolis Dentist

We all have them – in fact, we have two sets within our lifetimes. They help us eat, speak and plenty of other functions. But have you ever stopped to think, what exactly are these hard, white nuggets in our mouths? Believe it or not, but teeth are complicated structures. Let’s start from the outside and work our way in…

The visible surface of the tooth is known as enamel. Enamel is typically light yellow to white in color, but is semi translucent, so when you are looking at the color of your teeth, you are looking at both the enamel and underlying dentin.

Enamel covers the tooth above the gum line, below is covered in cementum. A yellowish substance, it contains less than half of the mineral content as enamel, making it much softer. However, cementum is to provide a surface to allow the periodontal ligaments in the gums to hold onto the tooth.

Below the enamel and cementum lies the dentin, both much softer than enamel and much less brittle. It’s also more prone to decay. Finally, within the dentin lies the tooth pulp. The pulp is soft tissue, filled with blood vessels and nerves that provide the tooth with oxygen, nutrients, and the ability to transmit ‘senses’ such as temperature, pain, and pressure.

While most people will only see the enamel surface of their teeth, you can see that there are lots of layers that make up a tooth, and all need proper dental care to maintain healthy teeth. By protecting the enamel with proper brushing, and treating cavities formed by decay before they damage the dentin or pulp, proper dental care will ensure a patient has healthy teeth – from pulp to enamel – well into old age.

Ever Wonder What a Tooth Is? | Indianapolis Dentist

We use them to eat, smile and speak, but have you ever stopped to think about what exactly your teeth are? Like, what exactly are these strong white teeth taking up space in your mouth? They may look basic, but teeth are actually complicated structures.

Enamel. The visible surface of the tooth is known as enamel. A hard, mineral surface, the enamel is typically light yellow to white in color, but is semi translucent, so the actual color of your tooth is determined by both the enamel and the underlying dentin. Made of a crystalized calcium phosphate known as hydroxyapatite, the enamel is both incredibly strong and incredibly brittle.

Cementum. While enamel covers to outside of the tooth above the gum line, below the gum line the surface of the tooth is covered in a substance known as cementum. A yellowish substance, it contains less than half of the mineral content as enamel, making it much softer. The primary purpose of cementum is to provide a surface to allow the periodontal ligaments in the gums to hold onto the tooth.

Dentin. Below the enamel and cementum lies the dentin. Dentin is a combination of mineralized hydroxyapatite, organic material and water, and is both much softer than enamel and much less brittle, making them more prone to decay and severe cavities.

Pulp. Finally, within the dentin lies the tooth pulp. The pulp is soft tissue, filled with blood vessels and nerves that provide the tooth with oxygen, nutrients, and the ability to transmit ‘senses’ such as temperature, pain, and pressure. The pulp also helps to form and repair dentin from within the tooth.
