If demineralization continues, a loss of enamel / hard tissue will occur. This loss of enamel creates an undermining of the outer surface and is called cavitation. It's almost like digging a tunnel underneath the ground. You are in the tunnel and have a small area of dirt / ground above you. Yes, if someone walks on the ground above the tunnel, the tunnel colapses. That's what happens in a cavity. The outer shell of enamel will colapse and a hole becomes evident.
One of the most common ways to check or verify areas of decay is through the use of an explorer. Using the tine
of the explorer, the enamel surface will be checked for areas of stickiness (enamel softness).
