Looking at the answers so far; they’re good answers but some still seem a little technical for ELI5. Think of it like a car. If your car gets a little dent because something hit it, it shouldn’t dent more on its own. If there is rust on the car, it’ll slowly eat away at that area until it’s taken care of properly. The rust is like a cavity and the dent is a tooth chip.
