Tooth enamel — not bone — is the hardest substance in the human body:
Tooth enamel, the outer layer of your teeth, holds the title of the hardest substance in the human body — even harder than bone. However, its strength faces a formidable challenge: your mouth is a thriving ecosystem teeming with over 300 species of bacteria in dental plaque alone.
Despite enamel’s remarkable durability, it can’t withstand the relentless assault of these bacteria without proper care.
Tooth decay, commonly referred to as cavities, develops when plaque builds up on the surface of the teeth.
This sticky biofilm harbors bacteria that produce acids as they digest sugars, gradually eroding enamel and leading to decay. Without intervention, this process can compromise the structural integrity of your teeth, underscoring the importance of good oral hygiene to protect your smile
