Not directly—but the bacteria that cause cavities can spread throughout your mouth. If decay-causing bacteria aren't removed with good brushing, flossing, and regular dental cleanings, they can build up on nearby teeth and increase the risk of new cavities developing.
A cavity itself doesn't "jump" from one tooth to another like an infection, but the conditions that caused the first cavity can affect surrounding teeth. That's why treating cavities early is important. Small cavities are often easier and less expensive to repair than larger ones.
