When you look at your teeth, you may see a smooth and glossy surface that you get daily use of. You bite, chew, speak, and smile with them, but they can do this because of the many layers that make up the structure. Each one plays a specific role that helps your grin be strong. Here’s more about each part of a tooth that can help you better understand why you should take great care of your oral health.
Strong and Sturdy Enamel
The outermost layer you see is your enamel. It’s what you brush and floss every day, but its main job is to protect the structures underneath from damage, bacteria, and temperature changes. In fact, it’s actually the strongest substance your body makes, more so than bone!
However, this doesn’t mean it’s invincible. It can erode because of attacks from bacteria or acidic foods, but it can’t regenerate itself. You can remineralize it, just be sure to use a fluoride toothpaste.
Sensitive Dentin
The dentin is right underneath the enamel, but it makes up most of a tooth’s overall structure. It has tiny channels that lead down to the nerve, meaning it’s especially helpful with feeling things like temperature.
Without it, your teeth wouldn’t be able to feel the difference between cold and hot foods. When dentin is exposed, you may experience sensitivity and you are also at a higher risk of cavities.
Protective Cementum
Your tooth roots aren’t covered by enamel, but rather by cementum. It’s mainly underneath your gumline, but it helps anchor your teeth into your jawbone. While it’s naturally softer than the layers mentioned above, it’s generally not an issue, as it also has the soft tissues of your mouth protecting it. Your gums can recede to expose it, so it’s important you do your part in avoiding this from happening by proper oral hygiene and routine visits to your dentist.
Living Inner Pulp
The innermost part of your tooth is the pulp. It’s a living tissue that has nerves and blood vessels. It helps keep the entire structure alive by delivering vital nutrients and sensation. It’s the most sensitive, so any damage or exposure can lead to discomfort. It can become infected because of a crack, but it can be removed to save your tooth.
In the end, your teeth are much more than just your enamel! Each part of it plays an essential role in keeping it strong and reliable. By taking good care of your oral health, you can ensure your smile stays the best it deserves to be.
