According to the Crest Pro-Health website, tooth pain that occurs when eating sweets is a common symptom of lost tooth enamel, a condition that commonly occurs in individuals who consume excessive acidic beverages and foods as well as in individuals who brush their teeth too hard. When the top layer of enamel is worn down, tooth sensitivity and pain are common when consuming sweets and cold or hot beverages.
WebMD explains that tooth enamel erosion occurs when plaque changes food starches into acids that erode the tooth enamel and cause sensitivity. Early enamel erosion causes mild pain and sensitivity, and late-stage erosion causes severe, jolting pain when eating sweets or drinking cold or hot beverages. Additional symptoms of enamel erosion include discoloration, indentation and cracks.
According to the Sensodyne website, 47 percent of people experience tooth pain when eating sugary foods. Employing healthy oral hygiene practices, using a soft toothbrush and minimizing consumption of acidic foods and beverages help prevent tooth sensitivity. Toothpastes and mouthwashes that contain extra fluoride work well to strengthen weakened enamel, and there are also toothpastes that are specially formulated with potassium nitrate that helps to protect the tooth nerves. Toothpastes that contain strontium acetate replace calcium in the teeth and protect the underlying nerves and tubules from future pain.
