What Determines the Longevity of Tooth Enamel?

Did you know that your tooth enamel is the hardest substance in the human body, but it cannot regenerate? That’s right, you have all of the natural tooth enamel that you will ever have in your lifetime once your permanent teeth come in. But how is that possible? It all comes down to the microscopic structure of the protective layer of the tooth. Continue reading to learn more about your teeth’s enamel and what you can do to protect it in the future.

How Is the Enamel So Long Lasting?

The long life of your enamel is thanks to its microscopic structure. It is made up of “enamel rods.” These consist of hydroxyapatite crystals that can be visualized as a result of modern technological advancements. These crystals are perfectly misaligned in a way that allows you to chew without causing the enamel to crack. This structure of enamel is what makes it the strongest part of the entire body, including your bones.

How Do You Protect Your Tooth Enamel?

Even though your enamel is extremely strong, the oral cavity is a hostile environment. Your teeth’s protective layer can become damaged over time. Fortunately, there are several ways you can preserve its integrity and make it last even longer:

• Fluoride: This natural mineral is known for strengthening tooth enamel and repairing early stages of tooth decay. It can also make your teeth more resistant to harmful acids in the mouth. Make sure that you are using a toothpaste and mouthwash that contains fluoride, therefore protecting your teeth.

• Brush carefully: If you brush too vigorously, you can damage your tooth enamel. Be sure to always use a soft bristled toothbrush and use short, gentle strokes for the most effective clean. If you just consumed something acidic, wait about an hour before brushing to avoid damage.

• Calcium: This mineral is effective at countering the acids in the mouth that cause tooth decay. It is also known for strengthening both your bones and teeth. Make sure to include calcium-rich foods in your diet. This includes cheese, milk, and other dairy products.

• Limit sugary foods: Foods and beverages that are high in sugar can put your tooth enamel in harms way. It’s best to save these things for occasion in order to preserve the integrity of your enamel.

• See your dentist: If you want to keep your teeth strong, seeing your dentist for cleanings and checkups is an important step. They can spot signs of cavities or teeth grinding before they cause significant damage to your tooth enamel.

As strong as your enamel is, you still should be taking steps to make it last. After all, it is the only natural tooth enamel you will ever have!
