When there are cracks on the enamel surface of the teeth, they may become sensitive to hot and cold. This also happens if the root structure of the teeth is exposed. Some reasons behind this condition are recession of gums, teeth grinding, excessive consumption of carbonated and aerated beverages, and overuse of agents that claim to whiten one’s teeth. To prevent the teeth from being overly sensitive to hot and cold, one must make sure to avoid using brushes that have hard bristles. Brushing in an overaggressive manner is also harmful. Using brushes with soft bristles, and gently cleaning the teeth is ideal.
