Definition
Enamel is the hard, outer layer of teeth, primarily composed of minerals, that protects the underlying dentin. It is the hardest substance in the human body but contains no living cells, meaning it cannot naturally regenerate once damaged.
Why it matters (in Poovi’s context)
Enamel is crucial for protecting teeth from wear, decay, and sensitivity. Its regeneration is a significant medical breakthrough for dental health.
