Strontium acetate hemihydrate is a compound used in some toothpastes to desensitize teeth to extremes of hot and cold, sweets, acids, or contact. Desensitizing toothpastes are specifically designed to block the exposed areas in teeth, which are the source of sensitivity. Tooth sensitivity, or "dentinal hypersensitivity" is one of the most common dental complaints. Almost one in four adults suffers from this problem, which can begin in a person’s twenties.
