How your teeth rot
How Does Tooth Decay Happen?
You can’t actually see what’s happening, but the process of tooth decay transitions from minor annoyance to major health issue very quickly. How does tooth decay happen? Two primary substances are to blame: sugar and bacteria. Whenever sugary and sticky foods are consumed, the bacteria on your teeth (usually in the form of sticky plaque) uses that sugar as “food” to produce acid.
After a steady dose of these so-called “acid attacks,” the tooth’s enamel starts to wear away. At first, you may notice small discolorations. Soon afterward, those tiny chinks in your tooth’s armor develop into small holes and blemishes called cavities. The plaque and cavities allow more acid to enter the tooth’s soft, vulnerable interior. Once the enemy (acid and bacteria) advance beyond the gates (enamel), it’s only a matter of time before the tooth starts to rot from the inside out.
