Tooth sensitivity is defined as discomfort in one or multiple teeth triggered by cold, hot, sour, or sweet foods/drinks, and even from breathing in cool air. This pain is sudden, sharp, and shoots deep to the nerve endings of the tooth. Cold sensitive teeth occur when the nerves of the tooth become exposed, resulting from either receding gum lines of deterioration of tooth enamel.
Cold sensitive teeth can be caused by a variety of factors, both internally and externally. Internally, disease or tooth decay, plaque buildup, and gum disease can make your teeth more sensitive to cold. Externally, brushing too hard, overusing whitening products, ingesting food or drinks with high acidity, and tooth grinding can expose the nerves of the teeth and make them more sensitive to cold.
