Symptoms Of Cavities

Pain When Biting Down

Pain when biting down can be another symptom of a cavity. This is caused because the nerve is less protected by enamel and the dentin layers of the tooth. The cavity causes pain in the tooth and the nerve when it is used for chewing food. Pain while biting down can also indicate an infection that may be caused by a cavity in the gum. While this symptom can indicate a cavity, it can also indicate physical damage that may have occurred. For example, a cracked or broken tooth is physical damage. This symptom should receive medical attention as soon as possible.
