A hairline split in a tooth can appear without warning - perhaps after biting down on something firm, catching an elbow during a game, yet even mild pressure counts. Though small, such a fracture may trigger discomfort, cause sensitivity to hot or cold, meanwhile compromising the tooth's structure gradually. Getting help from someone trained in oral care soon afterward prevents escalation, halting damage before it runs deeper.
