There are a few ways that your teeth might be cracked. Teeth are rather strong, yet in extreme scenarios they can chip or crack once in a while. Teeth might even break off if the problems are right. A few of the ways that this can take place consists of attacking down on something incredibly hard, trauma to the tooth or face, cavities or decay that we can the tooth, having sensations that do not sustain the tooth enamel and a few even more. While this is usually not painful, if a large enough piece of your tooth breaks off you might experience pain, especially if the nerve is damaged or exposed.
