What you're looking at is a cross-section of a human tooth — one of nature's most remarkable engineering achievements.
The outermost layer, enamel, is the hardest substance in the human body. Composed of about 96% mineral, it protects the tooth from daily wear, chewing forces, and acidic challenges.
Beneath the enamel lies dentin, a living tissue filled with thousands of microscopic tubules. These tiny channels transmit sensations such as heat, cold, and pain toward the center of the tooth.
At the core is the pulp — a living chamber containing blood vessels and nerves that nourish the tooth and keep it responsive throughout life.
The tooth is anchored to the jaw by its root, covered by cementum and connected to the surrounding bone through the periodontal ligament, a specialized tissue that acts like a shock absorber during chewing.
Strong as stone, yet alive and sensitive, every tooth is a masterpiece of biological design. Beyond helping us eat, teeth support speech, facial structure, and overall quality of life.
