What Is Tooth Enamel And Why Is It Important?

A radiant smile is a powerful asset, capable of leaving a lasting impression. At the forefront of maintaining oral health lies a remarkable component called tooth enamel. Often referred to as the "guardian" of our teeth, the enamel is a hard, mineralized substance that covers the outer layer of our teeth.

Tooth enamel is the hardest substance in the human body, even tougher than bone. It covers the visible part of the tooth, known as the crown, and acts as a shield for the underlying dentin and pulp, which house sensitive nerves and blood vessels. Composed predominantly of minerals, primarily hydroxyapatite crystals, the enamel is responsible for preserving the structural integrity of teeth and ensuring their longevity.

The importance of tooth enamel cannot be overstated. Beyond its protective role, enamel also contributes to the aesthetics of our smiles. Its translucent nature allows the underlying dentin, which is naturally yellowish, to shine through, giving teeth their characteristic pearly white appearance. Maintaining tooth enamel's integrity is essential for a radiant smile and overall oral well-being.

Have you ever wondered about What is the main function of enamel??and why is enamel important for your teeth? In this article, we will discuss all the details about what is tooth Enamel, its function and What does tooth enamel do?



Enamel’s main function is to protect your teeth from any damage, like chewing or biting, clenching, and grinding. At the same time, the enamel is a durable protectant for teeth that is susceptible to chipping and breaking. It also protects teeth from the possibility of pain due to temperatures and chemicals. When it erodes, you may be more sensitive to cold or hot foods or drinks, as well as sweets, as they travel through the cracks in your enamel to the nerves.  

Once enamel is lost, it cannot regenerate, leaving the tooth vulnerable to decay and sensitivity. Therefore, adopting preventive measures to preserve and protect tooth enamel is crucial.



Enamel is composed of around 90% minerals, with calcium and phosphorus being the primary components. These minerals combine to create rigid crystalline structures. Proteins constitute approximately 1% of enamel, while the remaining 4% is composed of water. Importantly, Tooth enamel does not have nerve or blood supply within it.

Is enamel stronger than bone?

Enamel is harder than bone and is considered the hardest substance in the human body. However, bone is more flexible and resilient than enamel.
