Dentine hypersensitivity is a sharp, sudden pain arising from the teeth when exposed to touch or hot and cold foods. If dental disease is not the cause of the pain, toothpastes containing potassium have been recommended to reduce tooth sensitivity. This review of trials found there was not enough evidence to show that potassium is effective in desensitising teeth. More research is needed.
