QUESTION: How long does it take for bacteria to start reacting to the food residue that is left on your teeth after you eat?
ANSWER: The California Dental Association informs us that is only takes 5 minutes for bacteria to begin digesting that food residue, breaking it down and forming acid that will begin to destroy the enamel on the surface of your teeth. Once the acid breaks through the enamel, the minerals inside your teeth will be dissolved and cavities will form.

ANSWER: No!!! The cavity will continue to grow bigger and deeper, unless it is repaired by a dentist. According to the California Dental Association:
"Tooth decay is an infection that will not heal without treatment. Children with cavities eat poorly, stop smiling and don't learn properly."
